wheel stud size for 69 camaro with ls1 conversion

[69projectKAOS]

hi, can someone tell me what size wheel stud i should use for my 69 camaro with a ls1 brake conversion. i also have 1 1/4 inch spacers that bolt onto the studs, then the wheel bolts to the spacers. if someone could give me a factory part # or size and how much longer i should get them that would help me get back on the road asap. Thanks -Dom

Are you asking which studs you should use in your hubs/axles or which studs you should use in your adapters? You're going to be limited in terms of length for the inner studs by the adapters since you don't want them to interfere with the wheels, so maximum length for your stud should be the (hub/axle flange thickness, .40" to .85") + (rotor hat thickness, .30") + (adapter thickness, 1.25") + (relief depth in the wheel mounting surface of the wheel, if any). If you're running the OE hubs/axles, then the .40" dimension is more likely. If you're running KORE3 or other styles of billet hubs, the flanges are typically substantially thicker.

Do you have a preference between metric or SAE? Press-in versus screw-in? There are a lot of options to choose from, so the more information the better IMHO.

im running stock hubs for now, what is the thickest stud i can use in my stock hubs, i want a good quality set . because my studs dont come close to filling the holes in the upgraded rotors i have that came with my ls1 conversion kit. i think that since the rotor kept moving on the studs they snapped due to that. thanks -Dom

will these do the trick? are they durable and last a long time?

The holes size in the rotor shouldn't matter since the hub should be hub-centric on the snout of the hub. The rotor should not ever move relative to the hub or wheel if the wheel studs remain properly torqued. The most likely cause for breaking wheel studs would be either under-torqued or over-torqued lug nuts, more commonly under-torqued.

The ARP #100-7708 studs would be a good quality wheel stud choice for you, however at 2.5" long with your factory hubs you may need to shorten them so they don't interfere with the backside of the wheels. Since the ARP's have a .509" knurl diameter, you'll definitely need to machine your hubs accordingly for the proper interference fit. While ARP arguably makes some of the best mass produced fasteners in the world, no level of quality will keep improperly installed and/or torqued wheel studs intact.

the studs that i had which broke are 2'' long, and im running a spacer so the extra half inch wont be a problem i think. and as far as the knurl diameter on the newer studs, i will have to have the stud holes widened to fit the bigger ones? thanks for your help-Dom
