Ikeya Formula Rear Knuckle Pillow Bushings (S13 / S14 / S15)

Worn or soft rear knuckle bushings cause lag in road feel and traction. Converting them to high-rigidity, high-quality pillow balls fixes this weak point.

Choose the version for your car with or without HICAS. Versions also differ for steel and aluminum knuckles — contact us if unsure.

Sold as a set for both sides.
