The Whiteline Transmission Member Bushings replace the soft rubber bushings with stronger Urethane bushings, reducing the amount of flex in the transmission support. They are placed between the lateral and the horizontal support of the transmission and eliminate the flex that is caused by having the soft rubber units in place. Improvements will be felt in shifting, and throttle input response.

IMPROVE GRIP, HANDLING & PERFORMANCE.

Cornering loads are spread more evenly across the tires delivering more grip and, frankly, that’s what it’s all about. You also get improved tire wear as your tires stay flatter and more upright. Comfort improves because your car sits flatter through bends meaning less movement inside the vehicle.

Replaced old ones with new. These are much better quality and install was pretty straightforward. Would recommend product.

Must have

Put these in along with group n trans mount in my driveway on ramps, not too bad and very happy with improved responsiveness, stiffer drivetrain, and improved shifter feel. The stock wrx trans mount is annoyingly soft, do yourself a favor and get these parts.

Chris,

Sounds like a solid upgrade—stiffer drivetrain and improved shifter feel make all the difference. Appreciate the detailed install tips and thank you for your 5 Star Review!! 🔥

Much smoother downshifts

Full disclosure, I've been upgrading the bushings for my driveline piece by piece. Because I've been adding them one by one and driving around for a bit before installing the next, it's given me a pretty good indication of the effectiveness of each one. I started with the Perrin Pitch mount right off the bat. No idea on what difference that made as I did it at like 150 miles on the odometer. I installed the rear differential inserts last weekend which helped make the back end feel more planted and reduced some of the "clunk" in the rear under hard shifting. My wife also noticed shifting was smoother. Not perfect, but smoother. Yesterday I installed the gearbox positive shift kit buy whiteline and I must say this one has been the most noticeable. I do (daily) a lot of spirited canyon driving and I'm constantly downshifting to hit that "perfect gear" into the turns. This product (in combination with the previously mentioned items) makes downshifting from 4th->3rd and 3rd->2nd feel almost as smooth as going from 6th to 5th or 5th to 4th. It the car jerks WAY less downshifting into those gears now, especially when rev matching. I highly recommend this, and the pitch mount as the FIRST things to do when tightening up your driveline. Amazing product and super easy to install. Monday, I'll be installing the Group N transmission mount to complete the setup. I'll write an update on that once I have it installed. Overall, I'm really pleased with the results. Especially in combination with the Cobb short shift plate, billet works ****, and brass shifter bushing... it's like a completely different beast. Everything is short, notchy, and feel much more solid and precision than before. Highly recommend all the previously mentioned products. In combination they make a world of difference.
