For those wanting to tame the RLAARLO 917 for on-road fun, these inserts provide much needed stability in cornering and acceleration for the rear of the car. They are a tight fit, and once pressed in place, use an 1/8 drill bit to size the hole.
The toe-in greatly increases cornering stability and the anti squat gives the rear-end better traction on acceleration.
I also recommend moving the shocks inward at the top and outwards at the bottom. a 1/8 spacer can be added to the rear shock lower mounting point to move them outwards. Lastly, be sure the sway bars are equally loaded side-to-side. I love these cars, but they don't come set-up properly.
