• Gearbox or axle code: Many listings are matched to a specific gearbox, such as VW/Audi 020, 02A, 02J, 02M, 02Q, DQ250 (02E), 0A6 (MQ500), 01E, 01R or DL800, or Porsche PDK. BMW listings are matched to the 188 or 188K/215K axle. Confirm your code before ordering.
• Chassis code: Check your chassis, for example Golf Mk4–Mk7, Audi 8L/8P/8V or 8N/8J/8S, BMW E8X/E9X, Evo CZ4A or GR Yaris GXPA16.
• Front, rear, 2WD or AWD: AWD models may have separate front and rear units. The GR Yaris/GR Corolla, for example, has front and rear LSDs listed separately.
• Ring gear details: DQ250 DSG LSDs are listed for 20T or 25T ring gears. Some BMW units are specified for a 3.08+ ratio with a welded ring gear. Ring gear bolt kits are listed by thread size (M10, M12 or M14).
• Variant conditions: The Cusco Evo 7–9 LSD is listed for non-AYC models. The Cusco quick change 10" rear LSD is listed for 35 spline axles.

Installation by a professional is recommended. Setting up a differential means setting carrier bearing preload and ring gear backlash correctly. Depending on your gearbox, you may need a bearing kit, a shim kit (for example the 13-piece 0.65–1.25mm Wavetrac kit for 02Q/02M), an install kit or new ring gear bolts. Use the gear oil specified by the vehicle or differential manufacturer.

What does 1.5-way mean on a Cusco LSD?
A 1.5-way LSD locks more strongly under acceleration and more lightly on deceleration.

Do I need extra parts with a Wavetrac LSD?
That depends on your gearbox. Wavetrac offers matching bearing, shim, install and ARP bolt kits for many applications, so check the listings for your gearbox code.

Which DQ250 DSG LSD suits my car?
DQ250 units are listed for 2WD or AWD front and for 20T or 25T ring gears. Confirm your chassis and ring gear before ordering.

Will the Cusco Evo 7–9 LSD fit an AYC car?
No. That listing is for non-AYC Lancer Evolution 7–9 models.
