Part #: 100 - 7716. This ARP Wheel Stud Kit is designed for Subaru WRX and STI models. With a high tensile strength of 190,000 psi, these heat - treated, Cadmium - plated 8740 chrome moly ARP wheel studs are a must - have for cars with aggressive - fitting wheels or those used in competitive racing. They can easily withstand huge acceleration shock loads (shear) and lateral forces (elongation). Each package comes with 5 studs, enough for one wheel. The specs are: .565' Knurl / 12mm x 1.25 / 3' long, and this listing is for the extended wheel stud length.
Using this ARP wheel stud kit is straightforward. First, make sure your car is parked on a flat and stable surface. Loosen the existing wheel nuts and remove the wheel. Then, replace the old wheel studs with the ones from this kit. Tighten the new studs properly, but don't over - tighten. When installing the wheel back, make sure it fits snugly. Note that each package only has 5 studs, so you'll need to buy multiple packages if you want to replace all the studs on your car. For maintenance, regularly check the tightness of the studs. If you notice any looseness or damage, replace the studs immediately. Keep the studs clean and dry to prevent rust and corrosion.
