The camber setting in your alignment is one of the most crucial aspects of your suspension and the overall driving experience. Unfortunately, most BMWs do not have a camber adjustment in the front and a limited adjustment in the rear. This can be frustrating because camber comes into play whenever you make changes to the suspension or when you want more negative camber for more grip and better handling. There are multiple reasons to adjust camber -

• You want more front end grip to reduce understeer and create a more balanced handling scenario,
•  You have lowered the car and need to reduce negative camber due to inside tire wear
•  You added wider tires or wheels and need extra clearance to bodywork,
•  Your car was in an accident or collision and the camber setting is now wrong. Note: there may be other factors to this situation and we recommend finding the root cause rather than a quick-fix.

We offer front fixed or adjustable camber plates or camber/caster plates, rear adjustable camber arms, and rear adjustable camber bushings from KMAC, Vorshlag, and also our own designs to fit your specific needs. In most cases, these adjustable camber kits are a direct replacement for the stock BMW part, enabling a seamless upgrade. Adjustable camber can be dialed-in using ordinary hand tools and most kits have reference marks for consistent and repeatable adjustments. No drilling, slotting, or welding required! Some kits perform specific functions and fit with specific types of suspensions (stock, stock-type, coil-over, etc). Give us a call if you need guidance in selecting the best camber plate option for your particular suspension or situation.

**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

Fits the following BMWs:
1999-2006 E46 BMW
