RedShift B-SPEC and C-SPEC Comp1W coilovers are the same race-bred RedShift Comp1W coilovers our customers have been winning with for years, built with sealed, serialized dampers so every competitor runs the required damper specification. Every kit includes front camber plates and RedShift standard springs; Swift springs in the same metric rates are an option. Our lb/in spring supplier, Hyperco, is going out of business, and we are researching other SAE-rate spring brands for a new supplier. Each kit is priced the same as our RedShift P1 Performance coilovers for that car, all of them are part of our 10% off Comp1W sale, and in-stock kits ship in about 2 weeks.

C-SPEC is the sealed spec coilover for SCCA's C-SPEC class; part numbers follow the spec-line format, for example A-18-CSPEC. B-SPEC kits are built for B-Spec cars (Fit, Yaris, Versa, Mini, Mazda2, Rio, Accent, Fiesta, Sonic, iA); part numbers look like A-28-BSPEC. RedShift B-SPEC coilovers are not yet legal for the SCCA B-Spec class - RedShift has proposed to the SCCA that they be allowed, and we hope the proposal is approved soon. Rebuilds on any B-SPEC or C-SPEC damper are $100 labor per damper (parts extra), with a 3-day turnaround.

RedShift customers have won many national championships over the years, including the reigning Gridlife Club SC champion - two years running on RedShift Comp1W coilovers. We know front-wheel-drive cars.
