The kit includes tuned, progressive-rate bump stops that maximize suspension travel on the lowered M5, eliminating the sudden \"bottoming out\" that commonly occurs when lowering a vehicle with springs alone. By allowing for full compression travel within the spring, the bump stops also optimize the effective spring rate — rewarding drivers with added mechanical grip, improved cornering power, and a more composed, comfortable ride compared to a spring set alone.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTuned Progressive-Rate Bump Stops:\u003c\/strong\u003e Purpose-built progressive-rate bump stops tuned specifically for the E39 M5 with Dinan lowering springs — not generic universal bump stops.
