Similar to Skunk2’s industry-leading Pro-C and Pro-SII Coilovers, Pro-ST Coilovers feature threaded shock bodies, Pro-ST Coilovers offer height adjustments independent of spring preload, which help maintain adequate suspension travel on lowered vehicles for improved performance without sacrificing comfort. Quick and precise ride-height adjustments can be made for dialing in corner balancing as well as for improved handling, responsiveness, and overall balance.
