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. 
If you are looking for a wider range of camber adjustability in the rear of you car, the IRP Adjustable rear lower control arm is exactly what you need! Built to be much stronger than stock, these rear control arms feature inner monoball bushings and are built of steel, reducing the weight as well. These are perfect for a lowered car or for a track car that needs a greater level of rear adjustment.

Looking to stiffen up your rear shock mount without going for a solid rear mount? The Polyurethane Rear Performance Strut Mount from IRP will give you the stiffer reinforcement without giving you the typical noise, vibration, and harshness that come with traditional performance strut mounts. The polyurethane also helps with preventing rear shock blowouts, a common problem for stock BMW rear mounts that are paired with stiffer than stock suspension.
The bearing sleeve and poly bushing are built to work with all stock style shocks such as Bilstein and H&R coilover and suspension kits.

The BMW F8X M2 M3 M4 Chassis Bracing is designed to enhance the rigidity and stability of the chassis, providing improved handling and performance for your BMW. Turner Motorsport offers this high-quality brace to support better driving dynamics and reduced flex during aggressive driving.
**For vehicles with coilover front suspension**
When looking to dial in your steering geometry and alignment for reduced tire where and/or better track handling, the stock suspension is quite limited. To fix this, you can install Camber/Caster plates such as these plates from IRP. Camber/Caster plates allow for adjustment of the top position of the shock's mounting position. These slight adjustments have a huge impact on the stance of the of the wheel when driving straight down the road and when turning into a corner. With simple adjustments, you can increase the grip of the tires in hard turns, improve tread life, or even just make an alignment correction for a vehicle with a lowered ride height.
The IRP Camber Caster plates are made of an aircraft grade aluminum body, for strength and low weight, with an adjustable mounting plate that utilizes a steel monoball mounting point. This makes the plate resistant to corrosion and prevents deformation even with the stiffest shocks and springs.

The main mounting bolt for the differential in the E36 is susceptible to shearing off during extreme driving conditions. This can cause internal damage to your diff, leaving you stranded at the track or on the side of the road. Active Autowerke's differential support bracket eliminates this issue forever in under an hour installation.

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.
325-365mm adjustment range.
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.

Rubber boots for longevity and durability.
Combat increased tire wear and frequent replacements caused by limited adjustability with these patented solutions. For over forty years, K-MAC has been pioneering fully-adjustable suspension components, allowing for precise camber adjustments and toe angle corrections, resulting in a true "full four-wheel alignment."
Upgrade your Mini's front top strut mounts with the K-MAC ultimate design. These mounts offer separate Camber and Caster adjustment, ensuring precise alignment even under load. Made from high-grade aircraft aluminum, they are durable and lightweight. With K-MAC's patented system, adjustments are quick and easy, allowing you to switch between Street and Race settings in just 30 seconds. The design also features heavy-duty centers encased in elastomer for extended life and minimal stack height.
Want the best performance option in shock tower mounts? IRP has created their pillow-ball rear shock mounts for just this need. These rear shock mounts are designed for use on the track and racing. This set of mounts will help your rear shocks perform the best they can in all conditions. The advantage to using a mount with spherical bearing is that it allows the shock to freely move off axis without side loading the shock shaft like rubber or polyurethane mounts do. Side loading a shock increases stiction and wear which decreases its efficiency. Because these are mounts without an isolator (rubber or polyurethane) to dampen road noise and vibrations we do not recommend them for street cars.
The bearing sleeve and poly bushing are built to work with all stock style shocks such as Bilstein and H&R coilover and suspension kits.
