The zero-offset butterfly valve is subjected to exhaust drive pressure equally on both halves of the valve

while also using both convection within the engine compartment and physical shielding to eliminate harmful levels of heat from ever reaching the actuator

This rear kit can be used only with "true" style one-piece rear coilovers

This kit works fine with F-Series steering rack but orten customers are willing to use fully hydraulic steering rack instead of electric version

then the car will drive even better with lowered ride height
