GKTech Rear Kinematics Kit for BMW F8X M2/M3/M4
$189.00
The GKTech F8X M2/M3/M4 Kinematics kit is a unique rear suspension geometry solution for BMW M2, M3, and M4 models.
Lowering your vehicle negatively effects roll center, bump steer and the toe curve. That is where the GK Kinematics Kit is beneficial, improving the roll center and camber geometry to more track focused values for a lowered vehicle.
This change does slightly flatten the rear toe curve, making it less aggressive. However, by pairing the Kinematics Kit and our bump steer adjustable toe arms, you can lower the toe arm position using the supplied spacers to correct the toe curve or even a more aggressive one, ensuring more predictable handling and drivability.
This can be seen in the comparison graphs in the product photos!
Kinematics Kit
This kit has been engineered through 3D scanning/ modeling and repositions the toe arm pickup points to restore optimal geometry while maintaining OEM-like handling feel.
Features:
Increased negative camber for more aggressive alignment options
Reduced roll moment arm for minimized body roll
Adjustable bump steer and roll center correction through eccentric design
Spherical bearings reduce bush deflection and provide smooth suspension travel
CNC Machined 6061-T6 aluminum body
COM10T PTFE-lined self-lubricating spherical bearings for longevity
Adjustable Toe Arms
The bump steer adjustable toe arms allow adjustment of rear toe and bump steer to adjust the vehicles rear toe, as well as complement the geometry changes introduced by the Kinematics Kit.
Features:
High-quality 5/8" Teflon-lined pillow ball rod ends for direct steering feedback
28mm OD, 3mm wall 4130 chromoly construction with CNC-machined ends
TIG welded and e-coated for a durable finish
Adjustable bump steer correction up to 4mm using included shims
CAD-designed and FEA-tested

FAQs
Will this fit my car?We can only confirm fitment for the vehicles listed above under "vehicle compatibility". If your car is not listed there, then we don't know if it will fit.
Do you make these to suit other cars?
We only sell the parts listed on our website. If it's not listed on our website, then we don't sell it. Sorry.
How long is the warranty on these arms?
All GKTECH suspension arms come with a lifetime warranty against manufacturing defects and the Teflon lined rose joints come with a 1 year replacement warranty.
We stock spare bearings so even after the 12 months is up we can still help with replacements, worse case scenario they're a 5/8" rose joint and are readily available through your local autoshop.
Are these suspension arms legal for use on street cars?
We recommend that you contact your local RTA for clarification/confirmation. Whether you use a suspension arm with a rose joint on public roads is at your discretion.
Are there any special tools required?
No, a spanner set will do the job which
