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.

ALTA Rear Control Arms are the ultimate upgrade for your MINI, replacing your rear lateral links with a solid and performance-focused design. These control arms enhance traction and handling while giving you precise control over camber and toe settings. The flexibility of ALTA control arms allows for fine-tuning without the hassle of removing and reinstalling the linkage. Simply adjust the lock nuts and twist the center section to achieve your desired settings.
These control arms are the perfect complement to other suspension products like springs, coilovers, or sway bars.
For a comprehensive rear end upgrade, consider purchasing two sets of control arms to replace both upper and lower control arms. This minimizes deflection from the OEM rubber bushings and reduces weight. Please note that on models with Xenon-style headlamps, some modifications to the leveling sensor mounting may be necessary. For additional details, consult your ALTA dealer or our Tech Department.
ALTA Rear Control Arms come with high-quality hardware, including corrosion-resistant spacers and Grade 8 adjustment nuts.

The OE thrust plate is more than just a belly panel that covers your oil pan; it plays a crucial role in chassis rigidity, impact safety, and handling dynamics. BMW emphasizes that a vehicle should not be driven or moved without the thrust panel in place due to its importance.
Inspired by BMW's upgrade of the front bumper carrier on the E46 M3 from aluminum to Kevlar during their LCI update, we have made a similar enhancement to the thrust plate with our RKP Carbon Front Thrust Panel.
Product Details:
Multi-layered for optimal rigidity and durability 20% stiffer and 50% lighter than the OE panel Reflective exhaust heat shielding included Replaces the large, heavy aluminum OE panel

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.
