I recently purchased a 75mm Wheel Stud Conversion Kit from APEX Race Parts to go with my APEX ARC-8 wheels. I chose the kit with hex head studs and silver lug nuts.
This kit makes wheel changing much easier and allows you to use spacers without having to buy extended lug bolts.
As the weather has been getting warmer, I decided it was the perfect time to install them with my summer wheels. So, I documented the process to share!
Step #1 – Loosen all 5 lug bolts while the car is on the ground.
Step #2 – Jack up the car, take off lug bolts, remove the wheel.
Step #3 – Apply a drop or two of thread-locker onto the threads at the short end of the stud.
Step #4 – Screw in the stud until it is hand-tight. Repeat these two steps until all 5 bolts have been inserted.
Step #5 – I bought the hex head stud kit, which accepts a 5mm hex key. I slid my 5mm hex key into a 5mm socket and attached it to a torque wrench with an adapter. Set your torque wrench to 25 ft/lbs and tighten all 5 studs. (You will need to have a friend press down the brakes while you are tightening the front studs. The e-brake will hold the rears while you tighten them.)
Step #6 – Slide the wheel back on the studs. Make sure it is centered on the hub. Tighten the supplied lug nuts onto all 5 studs.
Step #7 – Lower the car onto the ground. Grab your torque wrench again and set it to 88 ft/lbs. If you did not use a spacer, you will need a deep 17mm socket. Tighten all 5 lug nuts.Step #8 – Repeat these steps on the other 3 corners and enjoy!
