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 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.

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.

Upgrade your Mini's suspension with ALTA Adjustable Front Endlinks for the R55, R56, R57, R58, and R59 models. These endlinks allow for precise adjustment, optimizing your vehicle's handling and performance. Crafted with durability in mind, they offer enhanced stability and control, especially during aggressive driving. Installation is straightforward, making it easy to achieve the perfect setup for your Mini.
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

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.

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.
Fitment:
Fits the following Meyle and Lemforder arms with 21-22MM Hex.

After much anticipation, we are pleased to release our lowering spring kit for the BMW M3 G80 platform! Taking our experience from our highly popular F80 springs, the goal with this offering was to lower the M3 by a tasteful amount while keeping ride quality the same or better than stock. After multiple prototypes and valuable user feedback, we believe that we met our goal.
Our lowering springs are specifically designed to utilize the factory dampers. They are fully compatible with both standard as well as adaptive suspension. Each spring is made in the USA to our unique specifications for rates and geometries. The springs are made of high tensile chrome silicon and each unit is shot peened, pre-set, and 100% tested to ensure all the critical dimensions and rate/loads are within tolerance. The springs are then powder-coated with a stealth black finish for an OEM appearance.

When an E9X is lowered beyond the limits of just lowering springs, the rear wheels toe-in excessively. This excessive rear toe leads to premature wear, that many people attribute to an increase in negative camber. It has become a common belief that an extremely low vehicle will wear the tires wrong as a matter of consequence. It has become standard practice to go as low as you can and proceed to replace your tires every five to ten thousand miles. Whats more is that when the vehicle reaches a certain ride height, the factory arms become maxed out and there is no way to compensate and dial in the proper toe. You're left with an improperly aligned vehicle that is in effect worse off than it was with the stock suspension installed.
This is not only uneconomical but improper and unsafe. ECS Tuning is proud to offer a solution for this problem in the form of Rogue Engineering E9X adjustable rear toe arms. These arms allow for greater toe adjustment on vehicles that have been lowered with a coilover suspension. With the toe set properly the tires can contact the road properly this maximizes grip and minimizes wear.
