'Race Studs 101'
| It is essential that you select the correct size nut or stud for your application. If you are unsure of what you need please consult an expert familiar with your application and the components you have on your car. The following are some of the dimensions and parameters that you need to understand about your specific application before you purchase wheel fasteners from ACS.
Seat: Taper, Radius or Flat.
Radiused or Ball seats are, as the name suggests, ground on a specific radius suitable only for wheels with that exact same radius seat. This type of seat is common on OE German wheels. Mercedes often use a 12mm radius seat, VW/Audi use a 13mm seat and Porsche uses a 14mm radius seat.
