If you have a lot of bite at your track, all the cool kids are lowering the their ride heights as low as possible. Also be cool and raise your gearbox up to keep your outdrives straighter for more power in the turns. Raise your front and rear transmission 1mm, 2mm, or 3mm with this shim kit and drop it down so low that people will ask where your spinners and neon are.

Includes a 1 and 2mm shim for both the front and rear.
