StopTech Stainless Steel Braided Brake Lines provide a quicker; firmer; more consistent pedal response by maintaining consistent brake pressure. Additionally; stainless steel lines provide precision brake modulation; especially during threshold braking. The improvement in pedal feel is more dramatic on older vehicles where the factory rubber line may have softened and swelled due to age. A variety of end fittings are available to meet application needs. All fittings are engineered for proper fit and durability. All necessary brackets and fasteners are included with each line kit. PTFE inner liner is resistant to expansion under pressure. Stainless steel woven braid provides support and resistance to impacts and abrasion. Clear PVC cover protects against chaffing. Strain relief devices reinforce end fittings 1999 - 1999 BMW 323is, 1999 - 1999 BMW 328is, 1999 - 2000 BMW 323i, 1999 - 2000 BMW 328i, 2000 - 2000 BMW 323Ci, 2000 - 2000 BMW 328Ci, 2001 - 2006 BMW 325Ci, 2001 - 2006 BMW 325i, 2001 - 2006 BMW 325xi, 2001 - 2006 BMW 330Ci, 2001 - 2006 BMW 330i, 2001 - 2006 BMW M3, 2001 - 2015 BMW 320i, 2003 - 2008 BMW Z4, 2013 - 2015 BMW 320i xDrive
