Ride Pro Matched 23mm big bore touring car springs
Ride introduce the Pro Matched short big bore springs for electric touring cars. With the current trend of using low-profile shock towers and shorter shock absorbers conventional 25mm springs are too long to achieve a proper ride height. Therefore Ride now have 23mm long offerings available with an inner diameter of 15mm and an outer diameter of 18mm. The colour-coded springs come with plastic spacer rings for a wobble-free fit, are individually checked and matched to guarantee an equal spring rate and fit a wide range of touring car chassis. Ride advises that owners of cars that use 20mm springs may have to with check ride height compatibility.
