Core RC Hi Response TC Spring 2.5 - Blue

The Core RC Hi Response TC Spring 2.5 - Blue (SCH-CR843) is a linear-rate option developed by Schumacher engineers and top-level drivers for sharp, predictable handling. Designed for 1/10th touring and FWD platforms, the Hi Response concept uses fewer coils and a thinner wire to cut mass and boost suspension reaction.

Compared to typical alternatives, the Hi Response springs offer over a 40% weight saving, measured at approximately 5.2g per set of four, helping the chassis respond more quickly to track inputs and improving overall feel.
