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!

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.

**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.

Features:

  • Decreased understeer
  • Decreases outside edge tire wear
  • Aircraft Grade Aluminum Construction
  • Steel Monoball and Mounting Sleeves

Reinforces the strut towers against deformation while adding valuable triangulation to the front end for sharper, more predictable handling. Designed to prevent “mushrooming” and other distortion caused by rough roads or stiff suspension setups, these plates help maintain consistent suspension geometry by reducing unwanted chassis flex. The result? A more stable, confidence-inspiring front end under load. Strut tower plates are engineered to sit perfectly flush against the towers. If they don’t, it’s a sign the towers have experienced some deformation. In minor cases, this can often be corrected using a block of wood and a hammer to carefully restore the mounting surface.

An integral part on E46 M3 is the rear chassis "V-Brace" (BMW # 33312229899) found on all 2001-06 Convertibles and Coupe (including the CSL). This brace attaches to the outward points of the rear chassis and to the area near the rear subframe carrier. Since some of these vehicles are now over 20 years old, we have been seeing more and more of these start to rust away. We began studying the OEM part, curious as to why they were starting to rust away. We found that the two arms of the "V" are made from 38mm x 12mm (1.5" x 0.5") hollow square steel tubing, pressed ends and welded to a junction plate joining them with welds holding the arms at a specific angle. Since the arms are hollow, it helps keep the overall weight down, but does little to prevent corrosion since it is difficult to paint/coat a hollow tube. A Google search turned up very little other than used ones on eBay and new ones that turned out to be in short supply from the BMW dealer (not surprising since the car is over 20 years old). Determined to make something better, we began our engineering and R&D process. Goals of our Design; Modular design, since packaging and shipping something this large would probably be too expensive Costs would dictate material and manufacturing methods Lighter weight would be a secondary (or tertiary) goal, but also keeping in mind costs Corrosion resistant, so it would not rust from the inside out, like the OEM version After weighing the material, manufacturing and cost options, we decided to go with a fully CNC'd ACQ 6061-T6 aluminum assembly. The concept is to machine two identical arms (one part number) and have them joined with a "junction plate". The arms would be secured to the plate with Grade 8.8 grade hardware and the entire assembly would include replacement Grade 10.9 hardware to replace the original OEM hardware (which is probably original). Details of our Design; CNC'd 6061-T6 construction, secured with Grade 8.8 socket head cap screws. Included are replacement Grade 10.9 hardware to fit in the factory locations. About 4 lbs. fully assembled weight (vs. 6.25 lbs for OEM), about a 35% weight savings Anodized gray finish Modular design allows for one arm to be removed in case of exhaust removal requirement. Included in the Kit Two (2) arms of the brace assembly (they are idential) One (1) junction plate One (1) red spacer (this goes BETWEEN the brace and the chassis!) Two (2) blue spacers (these goes BETWEEN the brace and the chassis!) Four (4), M10 socket head cap screws Three (3), M10 flanged hex head bolts It is recommended that the holes used to mount the V-brace onto the car be cleaned before installation by running an M10x1.5 tap to clean each of the holes.

Location: Front
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.

This item fits the following BMWs:
1997-2003  E39 BMW  525i 528i 530i 540i (for cars with EDC)

Location: Front
Type: Street/Track, Stage 2
Bearing: PTFE-lined pillow-ball with thin polyurethane bushing

The Stage 2 KMAC plates are a mixed street/track camber/caster plate meant to be used in a variety of suspensions. 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. Bearing inserts and adapters included. The Stage 2 camber plates are shorter than a factory mount so may not be suitable for cars will little suspension travel. These are designed mainly for adding negative camber for improved handling and not for camber correction back to stock settings (see Stage 1 kit). 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.

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.

Fits the following BMW chassis:
E36 BMW All Submodels except for 318ti
E46 BMW All Submodels
E30 BMW All Submodels
