Product Details
These RS-R Down Sus lowering springs fit the 2014-2015 Infiniti Q50 3.7L AWD (V37).
RS-R Down Sus lowering springs for the V37 Q50 lower the car, reduce body roll and sharpen turn-in. Each set is made for this car, so drop, spring rate and factory damper tune stay in balance.
Racing Studio-R built its first suspension in Osaka in 1972. Each set is progressive-rate, cold-wound and heat-treated in-house in Japan, then matched to the factory shock valving and ride-height target of the specific chassis it bolts onto. Backed by RS-R’s 3-year / 50,000 km fatigue warranty.
