These brands are considered original equipment manufacturers (OEM) or at least OEM-quality suppliers, often matching the specs Audi uses on the assembly line.

Difference Between Genuine Parts and OEM Replacement Parts
- Genuine parts are made by the car manufacturer (Audi) or under their direct control, guaranteeing the exact specification, fit, and finish intended for the vehicle.
- OEM replacement parts are made by third-party manufacturers who supply parts that meet or closely match Audi’s specifications. They are generally made to the same standards but might differ slightly in material or finish.
- OEM parts are often less expensive than genuine Audi-branded parts but maintain reliability and compatibility.
- Non-OEM or aftermarket parts may vary widely in quality and performance; sticking to OEM or genuine keeps you safely on the road (and off the mechanic’s dance card).

So, if you want your Audi A3 to brake like it’s still new—choose Brembo or Bosch for the discs, paired with Brembo or TRW pads for excellent stopping power. If you want to save some cash without selling your car's soul, OEM parts from RIDEX or ATE are solid bets.
