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.
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.

BMW E31 Upper Rear Wishbone Ball Joint Bushing (Pair) provides an efficient and affordable solution for replacing the ball joint bushings in the upper rear control arm of your BMW E31. Unlike the costly full control arm replacement offered by BMW, this bushing set offers high-quality performance at a fraction of the price.
This bushing pair features a well-engineered rubber boot that has been designed to sit flush with the metal surface of the bushing, allowing for easy installation using standard press tools or a socket. The innovative design eliminates the need for a custom press tool and helps prevent damage to the boot during installation.
Made from durable polyurethane rubber, these bushings are built to withstand the elements and provide long-lasting performance. With OEM-level precision, they ensure a perfect fit and hassle-free, plug-and-play installation on the BMW E31.
**For vehicles with stock style springs**
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.

BMW E31 Rear Traction Rod is a high-quality replacement for the discontinued original rear traction rods on the BMW E31. The original rear traction rods suffered from durability issues due to the transparent boot material, which couldn’t withstand exposure to the elements. This issue was also seen with the ball joint bushings that used the same material. The new rear traction rods utilize durable polyurethane rubber, designed to stand up to the harshest elements and provide long-lasting performance.
Designed from scratch with the highest-quality materials, this rear traction rod is built to handle the weight and demands of the E31 chassis. It is engineered to match OEM dimensions exactly, ensuring a straightforward installation with no need for modifications. After extensive testing on multiple E31 models over thousands of miles, this rear traction rod has proven to deliver superior durability and performance.

BMW E31 Lower Ball Joint Bushing is an essential upgrade for ensuring the long-term performance of your BMW’s suspension system. The original ball joint bushings supplied by BMW, specifically the Lemforder bushings, often suffer from premature cracking due to their weak, transparent plastic boots. This deterioration allows dirt and grime to infiltrate, ultimately damaging the bushings and affecting your vehicle's suspension. The new bushing solution uses advanced polyurethane rubber, known for its ability to resist wear and tear from the elements, providing lasting durability.
Engineered with precision, the BMW E31 Lower Ball Joint Bushing is designed specifically to fit the E31 platform, ensuring it handles the vehicle's weight without compromise. The bushing features OEM dimensions for seamless installation, making it a plug-and-play replacement that requires no additional modifications.
Swapping in E46 control arms into your E30 or E36 significantly increases negative camber by widening the track width and also gives you more clearance for more steering angle. Condor's CNC machined control arm brackets are made from solid steel and are fitted with a solid hex-shaped bushing. Designed for the street or the track, they hold the control arm steady and eliminate "shimmy" caused by stock bushings. They sharpen steering and improve overall driving feel. Comparable to the NLA Treehouse E36 & E30 Eyeball Arms.
Easiest install of any aftermarket solution
Allow clearance for E30 M50 Conversion exhaust
Street Approved, marginal increase in NVH
Easy Installation, no need for a press
CNC machined steel construction
Solid design without the maintenance of spherical bearings
Heavy-Duty replaceable UHMW insert. Don't be misinformed, UHMW is the best material for these inserts. Delrin is not self-lubricating and will crack and degrade over time.
Powder coated white for corrosion resistance
Improve caster with M3 offset geometry
Keep proper steering geometry under high loads
Made in the U.S.A.
Fitment:
E30 84-91 3 Series

Note that you will need to use E36 outer tie rods and E90 inner tie rods when installing in an E30 or E36
Be sure to measure your control arms to determine if you need 21mm or 23mm. Meyle makes a standard e46 control arm and a Heavy Duty control arm. Most HD arms have a hex that is larger in size (23mm). Lifetime Warranty

Swapping in E46 control arms into your E30 or E36 will significantly increase negative camber by widening the track width and will also give you more clearance for more steering angle. Condor's conversion bushings are machined from UHMW due to its high rigidity and low coefficient of friction allowing for minimal suspension bushing deflection (geometry change). They've designed them offset to re-center the wheel and give your e30/e36 the correct caster. They will include a stainless-steel insert that tightly presses over the hex pattern on the E46 control arms. You do not need to grind down your control arms or make any other modifications to your chassis. Please note that you will need to use E36 outer tie rods and E90 inner tie rods when installing in an E30 or E36.

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.
