ECS Stainless Caliper Guide Bolt - 54mm Length - E53 E6X E82 E9X Z4
The caliper sliding bolts are one of the most overlooked wear items in your braking system. Subjected to constant motion and often without adequate lubrication the guide bolts see a lot of wear and tear. Factory BMW caliper guide bolts are very expensive from the dealer - these 304 stainless steel bolts are less than half the price and provide outstanding resistance to corrosion and wear. They are manufacturered with tighter tolerances than the factory bolts too.
Price is per bolt unless noted (2 required per caliper).
