Welcome to Yellow-Speed Racing
Yellow Speed coilovers are produced to a high quality standard with strict quality controls and are backed by extensive research. Our shocks have been found underneath from high performance street cars to full race cars, like the D1 coilovers designed specifically w/ custom shock valving and spring rates on Sylvia S15, Supra JZA80 and IS250 racing cars in 2011 Gran Turismo D1 Grand Prix Series (Round 3 in AUTOPOLIS, Japan). Please kindly check the photos below taken from the event.
