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.
