Question Wheel Stud question

So... about to replace brake discs and was thinking of mounting wheel studs instead of using bolts. Need help determining correct length.

The rear wheels already have factory 17mm spacers as car originally came with option 413: 18" Turbo look wheels. Those spacers already have studs in them so it makes sense to have them up front as well. Front wheels will have 5mm spacers mounted for aesthetics.

What length studs to I need?

Also, do I need screw-in studs like these: Competition Wheel Studs (ea) or will the hub accept the press-in type?

You will need the threaded/screw in type since the hubs are threaded for the stock lug bolts.

Mine are Tarett 82mm with stock wheels. You may want to check with Tarett to be confirm the correct length with your spacers.

Just so you know, the front studs will stick out beyond the stock front wheel (they will be recessed for the stock rear wheel). This is due to the different size front and rear wheels (but same size stud for both). Some people don't like this look (and it might be minimized by using a front spacer) but I wanted you to know beforehand.

I used pro bullet nose 81mm in front and with 7mm spacers, they stick out slightly less than Tom's photo above with the same wheels.

Thanks!

Seeing those pictures makes me want to reconsider. Wouldn't shorter studs work? I mean, you just need a little more thread than the depth of the nut.

Another option to consider is to use the same 17mm spacer up front as you have in the rear. I originally installed 7mm front/ 15mm rear spacers on mine (although I'm using bolts, rather than lug nuts), but I thought the front tires were still too "recessed." I changed the fronts to 15mm too, and I like the look much better. No problems with clearance, either.

Bill, if I remember correctly, the rear spacers are there mainly to get the 9"-wide rear wheels with 52mm offset to sit right, and not for looks.

You could run different length studs front and rear to keep them from sticking out of the front wheels.

I have these:

M14x1.5 ACS Race Series Studs — Track-Studs.com

I got the ones in the 65mm length and that is plenty. I wish I had gotten longer in the back because they are recessed pretty deep in the wheel sockets (not a factor for you since you are just getting front). They stick out a little in front, just enough to easily thread the nuts on by hand. They don't have a bullet nose like some of the ones in this thread but they do have a little bit of unthreaded portion at the start to help get the nut threaded.

I did have them installed with some 7 mm spacers in the front and there was plenty of thread for that. I don't have the spacers installed now because I am running some different wheels now.

There is often a free code for shipping on rennlist from this vendor if you search for his most recently posted threads. Apex something.

Steve
