XRay XLP Spring-Set Progressive C 2.4–2.7 (2) XR308164

The XRay XLP Spring-Set Progressive C 2.4–2.7 (2) is a genuine XRay suspension spring pair designed for precise chassis balance and fine tuning. Supplied as two matched springs under part number XR308164, this set offers a progressive C-rate that begins at 2.4 and ramps to 2.7, helping to manage weight transfer through corners and over bumps.

Progressive-rate springs can refine initial response while maintaining support mid-corner, aiding traction on mixed-grip surfaces and improving compliance across kerbs. This balanced behaviour helps keep the car settled without sacrificing steering feel.
