The RACEOPT 1:8 GT Progressive Dynamic Spring - High Response brings a stepped spring rate that helps drivers control weight transfer and maintain traction through corners. The T3.2~3.4 profile balances initial compliance with a firmer ramp under heavy compression.
These springs are suited to drivers who want more consistent contact patch pressure and clearer feedback at the wheel. The progressive layout reduces sudden load shifts that can unsettle the chassis.
Targeted at 1:8 scale GT models, the springs fit common shock assemblies and are easy to install, letting you test settings and return to track action quickly.
