Whiteline Rear Subframe Mount Bushing for 2008-2014 Subaru WRX STI Base (GR/GV)

Whiteline built the Rear Subframe Mount Bushing for the 2008-2014 Subaru WRX STI Base. It goes on the rear of the vehicle. Order it as part number KDT907. The chassis code on the listing is GR/GV. You receive 8 bushings and 4 tubes. Whiteline”s note for this fit: Positive Traction Kit: Locks Subframe To Body. The listing names the Base trim.

The rear subframe is the cradle that the rear suspension arms bolt to, and the car is attached to it through rubber mounts that are soft on purpose. That softness lets the subframe shift under hard cornering or acceleration, which dulls the feel of the rear end. A firmer bushing set holds the subframe in position, so the rear responds more directly to steering and throttle. This is a positive traction style kit, designed to lock the subframe to the body.

Expect a difficult job of about 4 hours. An alignment is required after installation. Other Whiteline parts we list for the WRX STI: Adjustable Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Heavy Duty 20mm Rear Sway Bar.
