Ikeya Formula Adjuster Rear Lower Arms (S13 / S14 / S15)

Corrects the rear roll center to line up with the front, curing the rear squat-and-collapse feeling under high G that stock arms give on a lowered car. Better arm angles restore usable stroke for smooth, controllable traction, and the adjuster lets you change rear track width for more mechanical grip.

Recommended with Ikeya Formula front lower arms and tie rod ends. If your car uses a rear subframe or knuckles from another model, contact us before ordering.

Sold as a left/right set.
