Wheel hop or traction issues? We have the solution! Optimize your vehicle's instant center and improve forward traction by lowering the rear of the lower control arm 2", 2-3/4", or 3-1/4". These bolt-in brackets are CAD designed to accommodate factory lower control arms as well as all popular aftermarket styles. Robust flanges inside the brackets add reinforcement and ensure factory bushings bolt right in. Brackets installed can provide an average 0.10 second (or better) 60-foot reduction and an overall improvement in launch consistency. Brackets are constructed of 3/16" mild steel and CNC laser cut for precision tolerances. Relocation brackets are designed to work on both lowered and non-lowered vehicles and feature multiple settings to optimize vehicle handling and traction. Welding recommended on cars running drag radials or slicks and faster than 11 second ¼ mile time.
