Rather than combining mismatched aftermarket parts, Bilstein tunes the shock valving specifically to match the Eibach spring rate and reduced ride height, delivering tighter body control and reduced squat and dive.\u003c\/p\u003e\u003cp\u003eThe result is a car that sits about 1\"-1.5\" lower with noticeably less body roll and sharper handling, while staying close to factory ride comfort. It's a fit-and-forget kit - install once and both components work together as designed. Backed by Bilstein's 2-year warranty and Eibach's 5-year spring warranty.\u003c\/p\u003e\u003cmeta name=\"description\" content=\"Enhance your BMW Z4 E89 with the Bilstein B12 Pro-Kit.
