LS400 brake upgrade, need longer studs
Good morning guys. So I finally installed the LS400 upgrade that I've wanted to do for some time. I had to buy larger 18" wheels, as the current 18's didn't even come close. My question is that I do have to use spacers to clear completely, but only 8-10mm. I'm thinking I would like to add longer wheel studs, just to be safe and ensure safe engagement of the lugs. Local auto parts shop is useless. Does anyone have the correct Dorman part number that would add a few mm to stud length for better / stronger lug engagement?
I didn't count the turns yet when I installed (car is in winter storage), just feel that I needed more. Any help is appreciated. Thanks in advance!

I don't have a part number but you do need longer studs. The hat on the LS400 rotors is 3/8" thicker than the stock SC rotors, so that alone reduces your threads by that amount. Add a 8 mm spacer and you have reduced the threads holding your wheel on to very few. I read one post on an early thread where the wheel fell off when a person used a 1/2" spacer.
I don't use spacers (GS350 wheels) but if I did I would use longer studs.

According to a few different parts listings I referenced, LS400 rotors are 53.1 mm thick and SC400 rotors are 50.8 mm. That 2.3 mm difference is 0.091", whereas 3/8" (0.375") would be 9.5 mm. So, the stated 3/8" is off by a factor of five.
