My son-in-law made the front bumper and brush guard and did a really nice job. He also replaced the OEM shocks with Bilsteins. The OEM shocks had no rebound whatsoever and the Bilsteins have made a nice difference. I dropped the tire pressure from 35psi to 25psi and that made a difference too. Might try 20psi, we'll see. The motor has a stage 2 from Vivid Racing and it runs great. Definitely enjoying the Roxor.
