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.\u003cbr\u003e\u003cbr\u003eThis change does slightly flatten the rear toe curve, making it less aggressive. However, by pairing the Kinematics Kit and GKTech's 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.\u003cbr\u003e\u003cbr\u003eThis can be seen in the comparison graphs in the product photos!\u003c\/p\u003e\n\u003ch5\u003eKinematics Kit\u003c\/h5\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eIncreased negative camber for more aggressive alignment options\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eReduced roll moment arm for minimized body roll\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAdjustable bump steer and roll center correction through eccentric design\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSpherical bearings reduce bush deflection and provide smooth suspension travel\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCNC Machined 6061-T6 aluminum body\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCOM10T PTFE-lined self-lubricating spherical bearings for longevity\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eAdjustable Toe Arms\u003c\/h5\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eHigh-quality 5\/8\" Teflon-lined pillow ball rod ends for direct steering feedback\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e28mm OD, 3mm wall 4130 chromoly construction with CNC-machined ends\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTIG welded and e-coated for a durable finish\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAdjustable bump steer correction up to 4mm using included shims\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCAD-designed and FEA-tested\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eVehicle Compatibility\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eBMW F80 M3 \/ M3 Competition\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBMW F82 \/ F83 M4 \/ M4 Competition\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBMW F87 M2 \/ M2 Competition\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBMW G80 M3 \/ M3 Competition\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBMW G82 M4 \/ M4 Competition\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBoth the kinematics kit and suspension arms are sold as a pair.\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNote: The Kinematics Kit must be used with GKTech Adjustable Toe Arms (included in this package).\u003cbr\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1 x F8X M2\/M3\/M4 Eccentric Rear Knuckle Bearing (F8XX-RKBK)\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch3\u003eOptions\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eDid you want toe arms?
