Are you still using those factory aluminum lug nuts that are prone to cracking, stripping, and seizing up? Save the hassle and switch to these steel nuts which are required for most organized track/race events.

Rennline's competition wheel studs offer customers the ability to get rid of those bulky factory lug bolts that make those quick tire changes so cumbersome. These studs are constructed of heat treated grade 8 steel to exceed the requirements outlined by SAE standards. These come standard with a Black Zinc coating which is far superior to the Black Oxide coating found on many other studs in the marketplace. Studs have been certified to meet ISO 898-1 class 10.9 requirements. These particular studs are an m14x1.5 thread commonly found on Porsche, Audi, and several other makes, and are available in 35mm, 45mm and 60mm lengths of useable thread. Sold as a complete kit with 20 studs and 20 nuts

Please note the 60mm studs are LONG. For OEM wheels, most aftermarket wheels and even with most spacers 45mm will be long enough. Please measure and confirm you need this long of a stud before ordering the 60mm kit. The 35mm studs will be long enough if you have up to a 7mm spacer. 7mm and above please buy the 45mm studs. The 60mm studs are only necessary if you are running a spacer wider than 15mm.

• 15mm of threads on hub side
• 8mm of unthreaded shoulder for brake rotor
• 35mm, 45mm or 60mm of threaded stud from shoulder
