Ground Control Race Camber/Caster Plates for your Z4M are a true race-bred design using decades of motorsport knowledge and experience. These plates feature independent adjustment of camber and caster, CNC-machined components, aircraft-grade bearings, and proper stack height for optimal suspension travel. Unlike their Street camber plates, these are a full solid design for the ultimate in performance and precision. Camber is adjustable over 27mm of range.
A Ground Control exclusive is the use of two separate bearings to manage load instead of the more typical single spherical. The strut shaft is supported by a proprietary spherical bearing. This supports the strut during side loads and range of motion only. The weight of the car is supported by another, separate needle bearing made specifically for Ground Control with an incredibly high axial rating of 12,100lbs. The two bearing layout greatly reduces the load and strain that a single bearing must support, which means less wear, longer life, quieter operation, and better performance.
Z4M Race Camber Plate features:
- No cutting or modification required for install or use
- CNC-machined aluminum plates
- Anodized or plated components for corrosion resistance
- Aircraft-grade, waterproof spherical and needle bearings
- Dual bearing layout has less load demands than a single bearing design
- Steel slider inserts
- Rebuildable if you need to replace a bearing or hardware
- Upper spring perch included
- Strut-specific hardware included

Ground Control has been engineering suspension mounts for competition use since 1980. Their camber plates are based on this rich history of custom suspensions for all types of driving - street, track, and mixed use. Each camber plate is a ground-up design for its intended use, not a compromise. Ground Control-branded parts have a limited lifetime warranty (bearings excluded). Bearings have a 1 year warranty.
Not recommended for street use. See the Ground Control Street Camber Plates which are similar but have a urethane bushing to absorb NVH.
