Ground Control Street Camber/Caster Plates for your F80 M3, F82 M4, and F87 M2 Competition are based on their race-proven designs but with special features to optimize them for street-use. This not a racing mount, loosely adapted for the street. Features and goals differ between Street and Race designs. Ground Control properly engineers each kit for its intended use - the Street design has up to 3.5° of negative camber so you can improve performance but also correct for lowered suspensions. A urethane bushing isolates the bearing to absorb noise, vibration, and harshness much better than a solid metal design. Both camber and caster can be adjusted independently to correct or dial in alignment settings. Ground Control parts are covered with a limited lifetime warranty.
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.

Select your spring size and shock type from the menus above. The correct bearings, spacers, and hardware will be built into the camber plate for you. Ground Control applications cover all common spring sizes and many popular stock and performance dampers. Please select your required spring size and bolt spec from the drop-downs. F8X M3s and M4's were originally built with 3-bolt strut towers (-1/'15). Cars built after 1/'15 were supplied with 5-bolt strut towers (including M2 Competition).Spring Sizes:
2.25", 60mm (2.3"), 2.5", or any spring that uses the stock upper spring plate including sport/lowering springs.Shock Type:
AST, Bilstein, H&R, KONI, KW, MCS, Moton, Ohlins, and Stock/OEM. If your damper is not in the list, please select "Other" and one of our reps will contact you.
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).
