• Brakes: Dinan front and rear brake sets with drilled or slotted rotors, a PARAGON 6-piston front kit, brake pads and HEL braided lines.
• Suspension: AST, Öhlins and MOTON coilovers, AST and Dinan springs, SPL end links and rear arm bushings, and a HARDRACE front lower arm bush.
• Exhaust: Scorpion cat-back systems, centre sections, rear mufflers and de-cat pipes, plus a Dinan axle-back.
• Fuel system: Radium fuel rails, pump hangers, surge tank and filter kits, and Injector Dynamics XDS injectors.
• Engine and driveline: an aFe cold air intake, Dinan air filter and strut braces, KOYORAD radiator, GSC valve guides for the S54 and a Wavetrac rear diff.

• Right-hand drive: some parts are made for left-hand drive cars only, such as Radium's E46 M3 catch can kit. Australian cars are right-hand drive, so check for "LHD Only" in the title.
• Coupe or convertible: most parts fit both, but some fuel and body parts exclude the convertible. Check the title.
• M3 or regular 3 Series: the M3 has its own engine, brakes and front suspension. Pick parts that name the M3 or the S54.
• Age and past work: these cars are now 20 years old. Check bushes and mounts for wear, and confirm what previous owners have fitted before ordering matching parts.

Have a qualified workshop fit suspension, brake, fuel and engine parts. Get a wheel alignment after any suspension change, and bleed and road-test the brakes after brake work. Fuel and engine upgrades usually need a tune to suit, so ask us if you're unsure.
