Rebound adjustment controls the resistance as the damper extends after compression; it does not alter the spring rate. Ride height is adjusted through the spring platforms, so the two settings serve different purposes when establishing the car's setup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConfiguration differences\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eStreet\u003c\/strong\u003e configuration retains the original top mounts and separate rear spring and damper arrangement.
