Product details
EMPI's Xtra Long Wheel Studs, part 00-9496-0, are five M14-1.5 studs threaded on both ends with a 57 mm wheel side, for drums and rotors where a standard stud leaves too little thread for the lug nut. That is 27 mm more than EMPI's standard 30 mm stud and 22 mm more than its 35 mm long stud. Because they are studs, they stay clear of the brake parts inside the drum that an over-long lug bolt can hit.
A closed acorn nut can bottom on a stud this long before it seats against the wheel, so measure how far the stud stands out with the wheel and spacer bolted up. EMPI's long chrome 60-degree nuts (70-2862-0) take 1 3/4 inch of thread, and an open-ended nut is the other usual answer.

Fitment & Compatibility
The 10 mm rotor end threads into M14-1.5 lug-bolt holes, the stock size on 1968–1979 Beetles, 1968–1974 Karmann Ghias, and 1966–1973 Type 3s. Five studs fill one 5-lug hub; for 4-lug cars EMPI makes an extra-long 4-piece set, 00-9492-0.
Installation & Tuning Notes
Use thread locker on the rotor-side threads. After torquing, check that every nut is pulling the wheel tight rather than stopping on the end of the stud. EMPI makes that check the installer's job.
Common Questions
Why would I need studs this long?
Spacers and wheel adapters push the wheel outward, and a 30 mm stud may not reach far enough to give the nut full thread.
Can I use my regular acorn nuts?
Check first. If the stud is taller than the nut is deep, use a long or open-ended nut.
