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.
Fits the following BMW chassis:
E36 BMW All Submodels except for 318ti
E46 BMW All Submodels
E30 BMW All Submodels
E36 Z3 BMW All Submodels

**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.

A strut tower brace adds additional reinforcement to the front strut towers, tying them together for extra rigidity. This makes the whole structure stronger with less chassis flex. Handling and steering feel are improved with better turn-in and input with no downsides.
The IRP adjustable strut brace bar is a high quality brace that is constructed of 100% steel for guaranteed reinforcement and prevention of flex. The brace bar is painted black to ensure corrosion protection and to add to the looks of the engine bay.
Easily installed with basic hand tools.
Fits the following BMW chassis:

M7 Strut Reinforcement Plates 53-510101 are the ultimate solution for MINI owners facing the common issue of strut tower mushrooming caused by heavy impacts from shocks and low aspect ratio tires. Over time, MINI's shock towers can develop a convex shape, disrupting suspension alignment and leading to a noticeable pull to one side. The M7 Strut Reinforcement Plates (SRPs) address this problem by reinforcing the sheet metal and shock top plate, creating a durable surface that resists bending, even during hard impacts.
Designed specifically for the R50 Base Model Cooper, the R52 Convertible, and the R53 Cooper S, these SRPs are an essential upgrade for any MINI enthusiast. Constructed from CNC machined billet aluminum and black anodized for durability, the 1/2" (13mm) thick plates cover the entire surface of the strut tower, distributing loads evenly and providing peace of mind.
Whether you drive your MINI daily or push it to the limits on the track, M7 Strut Reinforcement Plates offer a cost-effective preventative measure against expensive suspension repairs. Easy to install in less than 20 minutes, the SRPs use the stock nuts for mounting and come with instructions that also guide you through fixing existing mushrooming.
If you are concerned about strut tower mushrooming and looking for improved handling, the M7 Strut Tower Brace (STB) is the solution. This is the ONLY strut tower brace on the market that features anti-mushrooming technology.
Repeatedly, we've heard the same complaint: strut towers mushroom after heavy impacts from shocks and low aspect ratio tires. Initially, the shock towers take on a barely visible convex shape, but if compared to the original sheet metal, you'll find the horizontal plane has moved as much as 3/8" upwards, making alignment nearly impossible.
This issue often shows up as a slight pull to the left or right, depending on which strut tower is affected. The M7 Strut Tower Brace's end mounting plates solve this problem by sandwiching the sheet metal and shock top plate, creating a reinforced surface that won't bend, even during hard impacts.
The M7 STB features 1/2" (13mm) thick end plates that add extra strength to the strut towers, preventing mushrooming and potentially costly repairs. The cross brace significantly improves handling by adding torsional stiffness to the front body structure, helping keep your tires planted and pointed in the direction you want to go, especially during hard turns. Machined from billet aluminum and matte black powder coated, the M7 Strut Tower Brace boasts a durable black finish that looks great and won't chip or oxidize.
We have customers who won't drive their new MINI off the lot without one and dealers that sell every new MINI with either the M7 Strut Reinforcement Plates or the M7 Strut Tower Brace.
Concerned about clearance? No worries. The M7 STB profile is designed to clear both stock and aftermarket cold air intakes and ECUs. Its modular design allows easy access to the oil filter or any other accessories that might normally be blocked and require removal of the entire brace.
Installation is a snap (often taking less than 20 minutes)! No need for new nuts—the brace uses the three stock nuts on each side. Installation instructions are available online by clicking the "INSTALLATION" link on this page.
The M7 Strut Reinforcement Plates and the M7 Strut Tower Brace are two separate products that address strut tower mushrooming (you only need one or the other).
If your MINI is mainly a daily driver, the M7 Strut Reinforcement Plates are sufficient. If you have performance driving in mind, the M7 Strut Tower Brace is what you're looking for!

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
E36 92-98 3 series & Z3
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
