Start with the goal
Sound, response, grip or a bigger power target. Tell us what you want from your M3 or M4 and let that guide the parts list.
Ask the fitment question
Share your model year, chassis, drivetrain, transmission and current modifications. Check compatibility before committing to a part.
Build it your way
Keep the catalog as your starting point, not a prescription. Choose the compromises that make sense for how you drive.
Before You Order
Which M3 and M4 is this page for?
This page is organized around the 2021+ G80 M3 and G82 M4 with the S58 engine. Check each product’s listed model years and chassis. Do not use this page as a fitment guide for older M3/M4 generations, the G83 convertible or other S58-powered models.
What should I check for RWD, xDrive or Competition fitment?
Check the exact drivetrain, transmission and trim requirements in the product listing. For suspension, also confirm electronic-damper compatibility and any required cancellation hardware. If the listing does not clearly cover your configuration, ask before ordering.
How do I choose brakes and suspension for my car?
Start with your brake package, including steel or carbon-ceramic rotors, front or rear axle and the intended use of the pad compound. For suspension, share your drivetrain, wheels, tires and target ride height. Have us review the part number if any fitment detail is unclear.
What should I check before power modules, tuning or downpipes?
Confirm ECU/software support, any unlock requirements, fuel choice and the complete hardware plan with your tuner. Do not assume a module replaces a calibration or supports your exact software. For downpipes, verify product fitment and the manufacturer’s documented emissions approvals for your vehicle and location before purchase.
