I have 20 of Dorman part number 610-408, which are equivalent to OEM part 90113-SD2-005, the 96-98 Acura TL rear wheel studs. They are 48mm long, which is slightly longer than stock Civic/Integra studs, but not nearly as long as the really long ARP extended studs. Perfect for track use and OEM quality. You will receive 2 packs of 10 (as pictured below)

I bought these just to have in case, but ended up not needing them.

$40 shipped for 20 studs total
