I can't give an honest review on this product alone because I installed the Perrin trans support my mount, the Perrin shifter bushing, Torque Solutions (racing) trans mount insert all together. Combining all of these in conjunction with the mtech shift springs and Motul fluid, the car feels like a million bucks. The shifts are incredibly solid. It puts the power to the ground so efficiently. It feels like I gains about 20 ft lbs and just the overall feel and experience is awesome. Vibration isn't that bad but definitely more than stock. Highly recommend these parts together.
