FAQ
Is Hipermax R good for the street?
It is HKS's track-oriented coilover with high spring rates and pillowball mounts, so expect a firm ride. For a softer street setup, ask us about HKS Hipermax S or the HM Touring spring kit.
Can the damping be adjusted?
Yes, in 30 levels.
How long does shipping take?
Delivery times vary by part because many items ship directly from the manufacturer or distributor. Message us before ordering and we'll confirm current lead time.
Can I return it?
Yes. Returns are accepted within 30 days of delivery. The customer pays return shipping, and a restocking fee of up to 20% may apply.
