• Brake size: Mk7.5 GTIs came with 312mm or larger 340mm front brakes depending on model. Match rotors and pads to what is fitted.
• Mk7 or Mk7.5: engine and most chassis parts are shared, but some exhausts, such as the APR and Borla cat-backs, are listed for the Mk7.5 only.
• Front diff: some GTI models have a factory electronically controlled front diff. Check your model before choosing a Wavetrac and its fitting kits.

Have a qualified workshop fit suspension, brake, driveline and engine parts. Get a wheel alignment after any suspension change, and bleed and road-test the brakes after brake work. Intake, intercooler and downpipe upgrades work best with a tune, such as the COBB Accessport.
