Suspension Secrets Adjustable Camber & Caster Plates – BMW E90 / E92 M3

As standard, the BMW E92 / E90 M3 suffers from understeer. This is fundamentally due to a lack of camber at the front axle. Therefore, the only way to fully remove the understeer from the chassis is to increase the camber at the front axle.

Designed, developed and manufactured 100% in house by our team of engineers here at Suspension Secrets, we have created the solution to adding more front axle camber on your E92 / E90 M3 with our adjustable camber caster plates. Our camber plates offer multiple different positions to set the camber to, offering setups ideal anywhere from a daily used road car all the way to an all out track car and everything in between.

Our camber plates have also been designed to work directly with your stock suspension system as well as vehicle fitted with lowering springs and any coilover that is designed to work with the OEM top mounts such as a KW V3 coilover. These camber plates also maintain the same bump/droop ratio as the standard top mount and they also do not affect the ride height of the car. They are also supplied with an integrated operate spring platform to allow the spring assembly to rotate independently of the camber plate, similar to the OEM design to prevent any spring bind when in use to ensure you can increase your camber without any negative side effects. Our design also keeps the whole assembly together as a single unit, ensuring installation is as easy as possible.

Increasing the front axle camber reduces understeer by making the tyre work even more effectively through the corners. With the standard camber on the car, the tyre leans outward through the corners, causing the inside edges to lose contact with the road surface. This reduces grip and therefore, introduces understeer into the chassis. With the camber adjusted and set correctly with our camber plates, you are able to lean onto the full tyre through the corner, maximising grip and removing the understeer from the chassis. This not only increases grip but also improves tyre wear when the car is being driven hard.

Whilst developing the E92 M3 chassis our engineers noticed that by adding in a specific amount of caster into the front axle, it improved the steering response and feedback substantially, offering much more engaging and dynamic driving experience which also greatly increases the driver confidence, allowing you push even harder and have even ore fun. Not only does the additional caster improve steering feel, it also increases the dynamic camber gain of the front axle. This means that when you turn the wheels through the corner, the outside wheels gain even more camber for the car to lean onto, increasing cornering grip even further whilst not taking away from the braking traction capabilities of the car, making them an even more effective performance upgrade.
