• Shared parts: many suspension parts are listed for the 1, 2, 3 and 4 Series (F2X/F3X). Check that the title covers the F20.
• Adaptive dampers: cars with adaptive (EDC) dampers need a matching coilover kit or Öhlins' EDC cancellation kit.

Have a qualified workshop fit suspension, brake, cooling and engine parts. Get a wheel alignment after any suspension change and bleed and road-test the brakes after brake work. Intake, turbo and exhaust upgrades often need a tune to suit; ask us if you're unsure.
