Wheel stud conversion
 
Hey y'all. How many of you have converted to studs? What brand did you use? And did you use a length that allows for various spacers, or?

I went with 90 mm.
Better to be long than short
I bought them on amazon or ebay. Have had zero problems in almost 3 years

I can't remember how long the studs I purchased are, but they are long enough that the front studs stick out beyond the wheels (Turbo Twists). I got them from ECS, they have really nice kits with the studs and spacers (20mm) that are high quality. I later purchased another pair of spacers (15mm) off of eBay, and they quality wasn't nearly as good as the ECS parts.

Same, 92mm from Tarrett.

986 Wheel Studs

I took a quick look and I don't think that you could add 20mm spacers and still have the lug nut fully engaged on the threads. 10mm might be ok but I'd have to pull a wheel and take a measurement to be sure.

I run 25mm spaces on 90 mm studs and there are a few threads showing after the lug nut is torqued.
If you track your car, many clubs want to see at least 1/2 the stud diameter showing past the lug nut

When you're saying 90mm, are you talking overall length, like in this diagram? https://uploads.tapatalk-cdn.com/201...988bcde57b.jpg

Yes, 90mm is entire length

Also, the instalation instructions on some say to use red locktite. I used blue and have not had any issues. Red is considered "permenant" and probubly will require heating with a torch to remove.
Blue will hold them in, but you can break one loose if you have to with wrenches

If you track or AX your car, once you try studs, you won't want to go back to lugbolts. Makes tire changing super easy and fast.

Sure hope you are using the high heat locktite as regular blue or red will turn to liquid with enough heat and the studs will back out.

Studs shouldn't back out spontaneously regardless of loctite use or no, if the nuts are torqued properly. the only time studs without loctite should be able to "walk" out is during wheel-changing / nut-removal.

A properly torqued nut on a stud is at the same risk of coming-loose as a properly torqued bolt is.

Well - I've seen it happen. Everything torqued properly - but used regular blue loctite. Notes vibration on track, comes in all the studs on the right side are loose. I've run studs on my cars for many years, never used loctite, never needed to.

Same.

I've BROKEN plenty of studs, before we knew the benefits of hub-centric, hahaha. But I've never had one come loose / un-torqued on me.

Yup. They won't back out by theselves if they are tourqued.
In 3 years and countless wheel changes I have not had one loosen at all with blue locktite.

If you use red, and somhow break a stud, good luck getting it out. You may have to replace the hub
