Installation:
In order to correctly and safely install your ACS 'Track Studs it is important that you follow these instructions.
Verify that the original thread pitch of your bolts or studs matches the thread pitch of those you have purchased for installation. Failure to do this can result in permanent damage to your hubs.
Remove the original nuts or bolts and remove the wheels. Clean the threads in the hub with brake cleaner and then dry them completely. Use compressed air to blow out shavings and dirt.
Apply a small amount of medium strength thread locker to the short end of the stud to be installed. If your studs do not have a hex machined into them proceed to next step. Otherwise insert allen key and hand tighten the stud into the hub.
Screw two nuts onto the outer end of the new "Track Stud" and lock them together using two open or box end wrenches. Final tightening is accomplished by using a wrench on the outermost nut, rotating both nuts and the stud together. Studs should initially be tightened to approximately 15-20 ft/lbs. Make sure the unthreaded shoulder of the stud bottoms against the hub. Note if it did not bottom then you may need to chase the hub threads with a thread tap. (eg. 1.5mm)
After stud is securely fastened, remove outmost nut without loosening the stud. This is done by using the inner nut to hold the stud from rotating while using a 2nd wrench on the outher nut. After finishing installation, mount wheels and torque nuts to 80 ft/lbs. or factory recommended settings.
Test drive car. After first test drive recheck all studs as some may loosen due to manufacturing tolerances. If so, remove, re-apply thread locker and re-torque. Note: If any studs should ever loosen at an event. Do not be overly concerned. As long as the loose studs are hand tightened and fully engaged, the torquing of the wheel nut is enough to make even a loose stud & nut assembly perfectly safe for track use. It is advisable however that once back in your garage or shop, the studs are seated firmly using the procedure outlined in the steps above.
Do's and Dont's
Do not force your lug nuts or studs in with a wrench. They should initially be able to be turned by hand.
Never apply "antiseize" to the stud's thread which seats into the hub.
Keep the studs & nuts clean and dry or they may develop a light surface rust which many find cosmetically unappealing. To cure this, a very light coating of WD40 or similar may be applied to the tip and then wiped down before applying the lug nuts.
NEVER use acid based wheel cleaners on "Track-Studs" as it will immediately rust the hardware. We recommend "Greased Lightning", "Simple Green" or similar to clean your wheels and brakes.
