We have THREE completely different camber/caster plates for the e90.
We make three versions because it is a better solution than making one version fit every situation. Ground Control camber/caster plates do not compromise.
The street version is the only version to be used with street springs, and is designed with features that harmonize with more conservative springs.
Hybrid camber/caster plate are intended for race type springs, or aftermarket coilovers used primarily on the street.
The third camber/caster plate is a pure RACE plate, and is only intended for race cars with coilover springs. This has the largest range of adjustment, fastest adjustment, and is the thinnest plate. Solid metal bearings are also the most rigid.
Note: e90 plates have different geometry, street camber/caster plates cannot be interchanged, however the Ground Control RACE camber/caster plates have a large range of adjustment and are interchangeable
