Lowering a car on springs alone eats into bump travel, and the factory bump stop then becomes the first thing the suspension finds over a large compression. This kit swaps in progressive rate stops tuned specifically to Dinan's spring rates and lowered ride height, so the suspension works through its full compression stroke inside the spring instead of slamming into a hard stop. A progressive stop behaves like a rising rate secondary spring, which means it adds cornering support and mechanical grip rather than only cushioning an impact. The stops are molded from OE quality material and four come in the kit.
