The GKTECH S13 anti-squat reduction weld in kit has been designed for those with an S13 (or R32) rear subframe that want an increase in rear-end grip. Designed from a 3D scan with the addition of CMM data the brackets relocate the front pick up point for your rear lower control arm altering your suspension curves. Laser-cut, steel, and with simple step by step instructions makes modifying your subframe a heap easier than attempting to do it yourself without guidance.
S13/R32 rear subframes have a higher anti-squat value of 45%, changing the pitch of the rear lower control arm by relocating the front pick up near 2 inches lower you are replicating the geometry of an S14/S15 and changing the anti-squat value to 0%. This gives further traction through corner exit, bumps etc by allowing the car to squat (and actually use the suspension as intended). This is a common modification for anyone looking to get more forward bite on their S13 and we’ve now made it easier than ever.
In addition to reducing the anti-squat value, roll center is raised 20mm increasing roll stiffness, anti-lift is reduced from 80% to 20% assisting in braking by reducing wheel travel and preventing droop when hard braking. Bump steer is also reduced by 6mm at 100mm compression/rebound. In short, this is a MUST for S13/R32 owners looking for more traction.
