The Whiteline Flat Out Positive Shift Kit for the Subaru WRX and STI is an effective option to crisp up gear shifts. The Positive Shift kits include simple poly bushings that replace the soft OEM units, and the Motorsports version offers still a firmer bushing. This kit stiffens up the transmission mounting point that is underneath the transmission itself. The Whiteline Positive Shift Kit is great part to add to your STI at the same time you upgrade your transmission mount. The Whiteline Positive Shift kit installs easily with simple hand tools. All necessary hardware and instructions are included.
Def a must if you’re switching out your transmission mount...paired with Whiteline 22mm rear sway bar and Kart Boy end links car handles much tighter
Firms up ride, easy install. A must if you're already under your car.
Thank you Dane for suggesting these to me and making my driving experience better!
Amazing. The center of gravity for this car is even better with these installed. Solid part especially when compared to what was on it from oem
I replaced these while I was already under the car replacing the transmission mount. I dropped the entire T member section with the transmission mount and everything all still together. Took the T member section completely apart in a more comfortable position sitting next to the car and replaced these bushings at that time. The stock ones are quite wobbly and flexible and these ones are a lot firmer and cannot be flex'd nearly as much. Put the full T member back together next to the car, went under and bolted the group n transmission mount up, and then bolted the assembled T member up and torqued everything down... I read that the 12mm bolts are 26 ft lbs, 14mm are 45 ft lbs, and the 17mm are 80 ft lbs.
