Are you regularly on the track and pushing your F20/F21 M135i LCI or M140i to the limit? Then Speed Engineering have designed the right thing for you to cool your brake system! This kit also fits all M Sport LCI F20/F21 front bumpers.

Speed Engineering’s track kit is designed for the F20/F21 LCI (facelift version with M package bumper). Intended for regular track use, this brake cooling kit offers maximum cooling performance. They supply flow-optimized funnels that replace the original inlet funnels in the front bumper and the brake air duct, matching the supplied 51mm ducting hose. By channelling the airflow towards the centre of the brake disc to use the turbine effect, this kit cools the disc from the inside out for maximum braking performance and longevity.

Kit includes:

• 1x air duct inlet, left
• 1x air duct inlet, right
• 1x brake backing plate, left
• 1x brake backing plate, right
• 3m air ducting hose
• 4x hose clamps

IMPORTANT: The different models vary slightly in the wheel position, coupled with different chassis geometries, as well as wheel and tire combinations, it is impossible for us to cover all variants. In the worst case, the wheel could touch slightly when the steering wheel is fully turned (which should only be the case when parking), which cannot damage the tire.
