I started with the OB4 RTR. Added the CNC 17 tooth pulleys, rear diff bulkheads & brace, mid shaft blocks, & the Delrin CNC rear lower arms. The car is all but bullet proof at this point. Never had a problem with fit. 50 wt oil in the shocks. 100,000 wt /front diff, 50,000 wt/rear diff. I'm looking to find some stiffer competition, Mugens and Serpents. In our little parking lot group that sets up a track w/cones even other OB4s cant stay with mine, driving skills and set up right?
Is the OB4 a Mugen or Serpent? No. Though from my limited experience its very competative. I'll tell you guys how I do against this kid who has good skills & an Impluse, LOL.
