We use thrust sheets where possible on all of our custom coilover kits. Here is why:

Thrust sheets provide a variety of benefits to coilover systems. As a spring becomes compressed the coils attempt to distribute the energy by unwinding. This is called twisted force. The unwinding makes the spring rate irregular. By allowing the spring to smoothly rotate around the perch during compression, the spring rate will return to normal. Thrust sheets also help dampening and rebound of struts too. Thrust sheet?s bearing action allowing the rotation of a spring allow the load on the spring to be more evenly Distributed which reduces lateral shock shaft load. Increased lateral load on shock shafts cause a reduction in the struts ability to rely on valves for dampening force.



Have look at this write up with a TEIN to Swift conversion using Swift springs and thrust sheets:
