which front wheel studs do i need for LS1 brake conversion

[SatisTraction]

i have been searching for hours i know i need new ones but i am not sure what size i need and i am about to go on the 2 hour trip to a parts store :eek: sometimes living in the country is rough :lmao:

so the car is a 69 camaro and the brakes are 99 ls1. what studs?

12mm x 1.5 roughly 2.5" length.

Advance auto will have the factory size lugs in there computer (used to work there)

Just give them the year/make/model of the camaro and your set.

Your OE studs are Dorman 610-259. These are 7/16-20 RH thread, have a .475" knurl diameter, and are about 1.75" long.

If you just want some additional length, them make overlength versions for thick wheel centers that are 2.125" long, Dorman #610-157(.1).

I would suggest you upgrade to a larger diameter wheel stud front and back assuming the car has more than just LS1 brakes. My preference would be either the M12 or 1/2-20 ARP's, #100-7708 & #100-7704 respectively. Buy them through Summit and save yourself the drive. ;)

"Raybestos brand the part # is 5000B for front studs"

Are these 1/2" or 7/16" studs?

edit: Never mind they are 7/16". Does anyone know of a 1/2" stud that will work?

I hope you're keeping in mind that you'll need to turn down the OD of your drum hub flange to fit inside of the LS1 rotor, which is even smaller than the 6" C5/C6 rotor hat. You can resize the holes in your hubs for any knurl diameter you want to run, but if you go too large then you start getting close to the OD of the flange with your knurl. I wouldn't recommend using anything with a knurl diameter larger than .563", which should help rule out some of the ~75 OE options listed on Dorman's website, http://www.rbinc.com/. They have pictures for most of the wheel studs they offer, which should at least allow you to pick of few of your favorites and then head to your local autoparts store.

I'm using the c4 rotor and a c5 caliper for a hybrid setup.
