Coming soon from Rêve D are three new UP series aluminium spring retainers for RWD drift cars chassis. Available as 0mm, +2mm and +4mm variants, the different height of the spring cups allows to adjust the position of the spring in relation to the shock body which has an influence on the lateral grip available with the +2mm and +4mm retainers increasing side bite without affecting overall traction. The cups also allow to use springs of different lengths which further helps to fine-tune traction available while the outer ring ensures the spring stays in place securely, preventing excessive vibration. The cups are machined from high-quality aluminium, they sport a black surface finish, machined silver edge details and white laser-engraved markings. Shipping of the spring retainers, that come as pairs, will start mid-April.
