The Function-T Coilover is a highly customizable, nickel-boron plated steel coilover. Different from existing chrome plating products, it is much more anti-corrosive and practically eliminates the spring seat seizing to the adjustable brackets. Optional X-R Coil springs utilize the newfound performance of the Function-T. Both 6 and 30 levels of adjustment are available. Custom spring rates are available for your own custom Function coilovers. All strut type suspensions use a reverse-monotube design coilover.
