Before you order
- Match the year and body style: the years, and for exhausts the body style, are in each listing name; parts for one generation rarely fit another.
- Clutch kits: confirm whether the kit includes a flywheel or reuses yours, and plan for the clutch to be bedded in as the maker describes.
- Coilovers: ride height and damping are adjustable, so plan for an alignment after installation.
- Emissions rules: check your state’s rules before installing parts that change the exhaust.
