Group N Hardened Bushings

STI hardened rubber bushings, either sold as a kit or individually, to improve handling, traction, and steering response. Rubber hardness is increased noticeably over stock parts (on all models including STI) but is within the limits for Group N use. Manufactured with the same quality and on the same production line as the OEM bushings.

Usually ships in 2 to 3 days.
