K2-Circuit Coilovers - 2004 - 2008 Acura TSX - Front 20k / Rear 16kApplications: 04 08 TSX Valve: K2 Race Valve This is our standard linear valve. Damper will get stiffer as the strut travels through its range of motion. This can give some harshness with very aggressive curbs. K2 DS1 Valve This is our semi digressive valve. We tried to find the happy balance between digressive and linear valving to give a balance of both worlds. Note: * Springs rates can be changed + 4K (up or down). * Recommended Spring Rates: F 20K
