Made in the USA These are the best rear shock mounts that we have found for the E30, E36, E46, Z3 & E85 Z4! Featuring CNC-machined billet aluminum mounting base with a replaceable urethane bushing (replacement bushings are just $15 and are changed in minutes!). These mounts are excellent for either street or track because of their low NVH (noise, vibration, and harshness). Plus, the superior design will far outlast the life of stock mounts - maybe even the car itself. You'll never think twice about your shock mounts again! These shock mounts are a direct replacement of the stock mounts so they fit all shocks with the BMW-standard 10mm shock shaft, including all factory and OEM shocks (Boge, Sachs, etc), H&R coil overs, Bilstein shocks and PSS, PSS9, PSS10 coil overs (except the B16 Ride Control Kit). This is sold as a package with new shock mount gaskets, washers, and Nyloc nuts.

Must re-use factory cupped washers!

These front adjustable camber/caster plates will replace your stock front upper strut bearing. The KMAC plates are a 'floating' design so camber and caster are adjusted together. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. Since these replace your stock strut bearings they are designed to work with a stock-type spring only. And when installed correctly will not significantly alter ride height. Adjustment is easily done by loosening the three nuts on top of the tower and sliding the camber plate into the position you want, then re-tighten the nuts. These mounts can be installed two ways - for camber correction or swapped side-side for increasing negative camber. Detailed instructions included.

Note: suspensions vary from manufacturer to manufacturer. Turner Motorsport cannot be responsible for fitment issues caused by non-stock or specialized coil-over suspensions. As with any race-derived component, additonal fabrication may be required.

Using a linear design (similar to OEM) with unique spring rates, Emmanuele Design's lowering springs are properly matched to the factory dampers, ensuring a ride quality that is slightly stiffer than stock, but predictable in nature. A progressive spring will typically be softer at light loads, then dramatically stiffen as compression increases. This makes it very hard to match dampening, and creates the bouncy feeling over light bumps. The linear design of these springs have a consistent rate as the spring sees higher load. On light bumps, it will allow the chassis to follow the road well (minimizing the bouncy feeling), while under heavy compression it will stiffen to prevent bottoming out. In our experience, this creates a much better overall ride quality. Compatible with adaptive suspension.

MMX Performance Lowering Springs for the BMW G42 230i strike the ideal balance between sharper handling and a more aggressive stance, all without compromising ride comfort. With a drop of approximately 20mm at the front and 15mm at the rear, the G42 gains a more planted feel, offering improved responsiveness, lighter dynamics, and noticeably crisper turn-in. Lowering the car’s centre of gravity makes a real difference to the way it drives. Body roll is noticeably reduced, turn-in feels sharper, and overall dynamics are greatly improved, all while retaining the comfort and refinement you’d expect from a BMW. Thanks to carefully chosen progressive spring rates, low-speed ride quality remains smooth and, in fact, actually feels more composed around town. But push on and the G42’s chassis comes alive: it feels lighter on its feet, more direct, and properly responsive through the corners. Just what the 230i needed. Visually, the difference is just as striking. The lower ride height gives the car a more aggressive, purposeful stance without being over-the-top. Go any lower or firmer than these, and you risk upsetting the balance, leading to a crashy, unsettled ride. That’s why MMX Springs are engineered specifically to work in harmony with both static and Adaptive M dampers. Features: 20mm front / 15mm rear drop for a sportier stance. Sharpened handling with reduced body roll. Smooth ride quality thanks to progressive spring rates. More responsive chassis feel at higher speeds. Compatible with adaptive & static dampers. No bouncing or crashing – perfectly matched spring rates Premium Metallic Grey finish Direct fit for BMW 230i G42

Rear adjustable camber and toe bushings for the E82/E9X non-M 3-series. These bushings allow you to adjust camber and toe beyond factory specs to either restore camber or add more. If you lowered your car and have too much camber these bushings can get you back to stock specs. On the flip side if you need more camber for the track or autocross, you can fine tune it with these too. These bushings press in and replace the existing rubber bushings. They are made from peformance urethane which will give more feedback and response to the driver. Sold as a set with a bushing extraction tool included.

OEM end links were designed to compliment standard ride height but when this is changed the car will now be pulling your anti-roll bar ends up, pushing it out of its operating window, and forcing the link to sit at a sharper angle. MMR Performance adjustable drop links are an essential upgrade to any lowered or performance car. When you lower your BMW without changing out your swaybar end links, a significant amount of preload is applied to the swaybar. This can negatively affect the handling characteristics of your vehicle and cause unwanted stress on a number of other suspension components. Features: Made from T6061 Aluminum Anodized in signature MMR Dark Anthracite Heavy-duty ball joints to ensure a long life span

Nearly every car manufactured in the modern era carries a dark secret – fully-adjustable suspension has been all but eliminated in the name of cost-cutting and assembly-line efficiency. What this means for you is increased tire wear and more frequent replacement, as a “full alignment” consists only of rudimentary toe-angle adjustment. For over forty years, K-MAC has been hard at work developing a solution to this problem with patented innovations in camber/caster plates and bushing kits, allowing easy adjustment and a true “full four-wheel alignment” to be performed by any competent shop. These bushings make camber adjustments possible for the first time, and improve the ability to complete toe angle adjustments. When used in conjunction with the K-MAC Camber and Toe kit and Rear Adjustable Trailing Arms allows full adjustability of the 5 multi-link rear arms and positive location. Bolt-on installation – insertion/extraction tube included! Easily adjusted on the car with basic hand tools Unique failsafe locking hardware – set & forget! High quality elastomer compound resists binding Hardened & nickel-chrome plated centers for maximum bushing life 2x the load area of stock bushings Spiral grease grooves

After much anticipation, we are pleased to release our lowering spring kit for the BMW M2 G87 platform! Taking our experience from our highly popular F-chassis offerings, the goal with this offering was to lower the M2 by a tasteful amount while keeping ride quality the same or better than stock. After multiple prototypes and valuable user feedback, we believe that we met our goal. 

Our lowering springs are specifically designed to utilize the factory dampers. They are fully compatible with both standard as well as adaptive suspension. Each spring is made in the USA to our unique specifications for rates and geometries. The springs are made of high tensile chrome silicon and each unit is shot peened, pre-set, and 100% tested to ensure all the critical dimensions and rate/loads are within tolerance. The springs are then powder-coated with a stealth black finish for an OEM appearance.

The MMX Performance adjustable drop links are a great choice for any lowered or hard-driven BMW to zero the pre-load on your anti-roll bar geometry. Plus, by replacing the stock rubber joints with motorsport-spec ball joint ends, you'll add valuable stiffness and precision to handling and steering dynamics.

The sway bar end link attaches the front anti-roll bar ends to the front damper. The OEM links were made the length they are for a reason, to complement the standard ride height.

When your ride height is altered, your vehicle's anti-roll bar ends are pulled up. With around 40mm of adjustable length, plus left and right threaded ends for easy length adjustment, the MMX adjustable sway bar end links allow you to adjust back to zero preload on your anti-roll bar - allowing it to operate exactly as it should once again.

Motorsport-spec ball joint ends using high-strength Teflon-lined steel means a much more direct response when turning into corners. By replacing the soft rubber bushing in the factory links with these motorsport-spec ball joints, cornering and steering responses are immediately sharpened. Importantly, rubber dust boots are fitted to protect the joints from road dirt and salt accumulation.

The lightweight CNC-machined T6-6061 aluminum bodies are anodized in our beautiful MMX gloss black coating to look good and stay looking good.

Features:

Manufactured in the UK from Aircraft grade T6-6061 aluminum billet.

Complete OE replacements

Anodized in signature MMX Gloss black.

Heavy-duty ball joints to ensure a long life span.

Direct replacement – can be used with either factory or Aftermarket rear anti-roll bar, and returned to standard at any time.

Designed with one aim in mind: to help achieve optimum suspension performance and geometric accuracy, and thus increase the effectiveness of your rear anti-roll bar.

Each heavy-duty, high-articulation rear end link attaches the rear anti-roll bar ends to the lower suspension arm. Replacing the failure-prone, weak plastic OEM links with our rigid billet aluminum links greatly reduces flex and allows a sharp, uncompromised transfer of suspension movement through to the sway bar.

As well as the link itself, extra stiffness and precision comes from replacing the flex-prone stock plastic ball joint with motorsport-spec ball joints. An especially valuable upgrade on older, higher mileage car.

Features:

Manufactured from Aircraft grade T6-6061 aluminum billet.

Complete OE replacements.

Our single-threaded ends make for easy length adjustment in-situ without having to detach and re-attach.

Each heavy-duty, high-articulation rear drop link.

Anodized in signature MMX Gloss black.

Heavy-duty ball joints to ensure a long life span.

Kit complete with everything you need.

Type: Street/Track, Stage 2
Upper spring perch: OEM-size, 60mm, and 2.5" included
Bearings: urethane OEM-type center bushing; lubricated radial thrust bearing on spring perch

KMAC camber/caster plates use a patented adjustment method designed for easy and rapid alignment adjustments. The KMAC design has a 'floating' inner camber plate, rather than slotted, to allow camber and caster to be adjusted together. To adjust, simply loosen the top three nuts on the strut tower and position the KMAC mount to match your desired alignment settings. The KMAC design allows more camber and caster adjustment because separate caster hardware is eliminated. While primarily designed to increase negative camber for track use these can also be used to fix alignment issues that cause uneven tire wear or unwanted handling behavior.

KMAC camber kits are the most complete kits on the market, with all of the common spring perch options and strut hardware included. The OEM size spring perch as well as 60mm and 2.5" spring isolators are included which makes it easy to upgrade from stock struts to coil overs without having to buy new camber plates. Or swap springs on your coil overs between 60mm and 2.5" without buying additional upper perches. Also included are the most common strut pin hardware - 14mm lower bearing adapters and 12x1.5, 12x1.75, and 14x1.5 top nuts. This takes the guesswork out of ordering the correct hardware for your strut type. The urethane main bushing is also replaceable and the camber plate parts are made from 7075-grade aluminum for a lifetime of camber plate use.

Fitment Note 1: replaces factory BMW strut mount with 3 mounting bolts (up to 12/2014 prodution). Not for cars with 5-bolt strut mounts.

Fitment Note 2: suspensions vary from manufacturer to manufacturer. The proper stacked height and clearances are required. K-MAC includes bearing adapters, spacers, and various top nuts but it is still the responsibility of the installer to ensure a correct and safe fitment.

Location: Front
Type: Street/Track, Stage 2
Bearings: main PTFE-lined pillow-ball bearing suspended in polyurethane; self-lubricating radial axial bearing/bushing in upper spring plate
Springs: includes OEM size upper spring perch, 60mm upper spring perch, and 2.5" upper spring perch

The Stage 3 KMAC plates are a mixed track and street camber/caster plate meant to be used in a variety of suspensions and setups. Since there is less bushing than on the Stage 1, more noise and vibration will reach the driver. The adjustment design is similar to the Stage 1 with a floating mount that sets camber and caster simultaneously. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. These plates can work on both coil over and stock-stype suspensions and upper spring perches are included for OEM springs, 60mm, and 2.5" coil over springs. The upper perch assembly incorporate a self-sliding radial bushing that allows the spring to spin during its travel instead of bind. This reduces tension on the spring and helps reduce noise and spring 'popping' noises. Bearing inserts, spacers for correct articulating angles, and 3 sizes of upper nut adapters included. The urethane bushings and bearings are replaceable if they wear out. These are designed mainly for adding negative camber for improved handling and not for camber correction back to stock settings (see Stage 1 kit). Basic instructions included but professional installation is required.

Note: suspensions vary from manufacturer to manufacturer. The proper stacked height and clearances are required. K-Mac includes bearing adapters, spacers, and various top nuts but it is still the responsibility of the installer to ensure a correct and safe fitment. As with any race-derived component, additonal fabrication may be required.

These front adjustable camber/caster plates will replace your stock front upper strut bearing. The KMAC plates are a 'floating' design so camber and caster are adjusted together. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. Since these replace your stock strut bearings they are designed to work with a stock-type spring only. And when installed correctly will not significantly alter ride height. Adjustment is easily done by loosening the three nuts on top of the tower and sliding the camber plate into the position you want, then re-tighten the nuts. These mounts can be installed two ways - for camber correction or swapped side-side for increasing negative camber. Detailed instructions included. This KMAC part number replaces BMW part number 31 33 1 139 437, the strut mount with the integrated upper spring plate.

Note: suspensions vary from manufacturer to manufacturer. Turner Motorsport cannot be responsible for fitment issues caused by non-stock or specialized coil-over suspensions. As with any race-derived component, additonal fabrication may be required.

Nearly every car manufactured in the modern era carries a dark secret – fully-adjustable suspension has been all but eliminated in the name of cost-cutting and assembly-line efficiency. What this means for you is increased tire wear and more frequent replacement, as a “full alignment” consists only of rudimentary toe-angle adjustment. For over forty years, K-MAC has been hard at work developing a solution to this problem with patented innovations in camber/caster plates and bushing kits, allowing easy adjustment and a true “full four-wheel alignment” to be performed by any competent shop. These bushings make camber adjustments possible for the first time, and improve the ability to complete toe angle adjustments. When used in conjunction with the K-MAC Camber and Toe kit and Rear Adjustable Trailing Arms allows full adjustability of the 5 multi-link rear arms and positive location. Bolt-on installation – insertion/extraction tube included! Easily adjusted on the car with basic hand tools Unique failsafe locking hardware – set & forget! High quality elastomer compound resists binding Hardened & nickel-chrome plated centers for maximum bushing life 2x the load area of stock bushings Spiral grease grooves

Type: Track, Stage 3
Bearing: PTFE-lined pillow-ball, no bushing

KMAC Stage 3 camber/caster plates are designed for track or race-only situations where comfort and noise are not the primary concerns. The Stage 3 camber plates use a pillowball bearing, solidly mounted within the camber plate for direct alignment of the strut shaft and no excess play or deflection. Stage 3 are designed to increase negative camber with their patented 'floating' adjustment that changes camber and caster together. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. Fitment is limited to race-only small diameter coil-over springs (not stock-type). Bearing inserts and adapters included. Detailed instructions included.

Note: suspensions vary from manufacturer to manufacturer. Turner Motorsport cannot be responsible for fitment issues caused by non-stock or specialized coil-over suspensions. As with any race-derived component, additonal fabrication may be required.

KMAC camber/caster plates use a patented adjustment method designed for easy and rapid alignment adjustments. The KMAC design has a 'floating' inner camber plate, rather than slotted, to allow camber and caster to be adjusted together. To adjust, simply loosen the top three nuts on the strut tower and position the KMAC mount to match your desired alignment settings. The KMAC design allows more camber and caster adjustment because separate caster hardware is eliminated. While primarily designed to increase negative camber for track use these can also be used to fix alignment issues that cause uneven tire wear or unwanted handling behavior.

Unlike conventional lowering springs, the MMR Height adjustable springs (HAS) for the current G80 M3, G82 M4 and G87 M2 gives you a fully customisable ride height adjustment. So, however you want your car to sit, our kit allows you to infinitely fine tune heights front and rear until you reach your ideal stance. By retaining the adaptive M dampers, this HAS solution is much more cost-effective than upgrading to coilover suspension, yet with the reassurance of keeping your high quality, sophisticated factory dampers in place. Best of both worlds. The method of height adjustment is exactly the same as on a coilover suspension setup. Four adjustable perches fit underneath the Sport Springs. With a simple turn up or down on the threaded platform to adjust ride height, you can tailor it until reaches your perfect height and rake. This generous sweep of adjustment provides a lowering range of 20-45mm on the front and 10-35mm at the rear (versus the factory ride height). The sport springs themselves, finished in beautiful MMR grey, are progressive rate springs, with rates carefully chosen to match with the damper characteristics of the factory M2, M3 & M4 G8x suspension. Features: A lowering range of 20-45mm on the front and 10-35mm at the rear. Retain adaptive M dampers. Fitment for RWD & X-Drive variants. Fitting is straightforward and installed with no modifications required. Easily returned to standard, should you ever wish. Specifically designed for the BMW G-Series platform. Kit complete with everything you need.
