Raising the rear wing of 1/10 scale Tekno vehicles like the EB410 and ET410 adds overall grip and makes the vehicle much more stable at high speeds. Doing so also improves jumping stability, along with stopping the wheels from hitting the wing during cornering. This shim raises the rear wing 5mm and comes with M3 screws to replace the stock ones. We recommend trying a stiffer rear spring when using this shim.
This shim is also available in a 7mm variant (VSR417)
