wheel studs.. which ones?
Looking to purchase a set of wheel studs for my new to me 3.6 gt3 (happy to be back) what size studs should I use? Rennline has a 65mm stud and nut package for $100 while I've seen some longer ones up to $90 for just the studs. Any brand better then the rest? Should I buy spares? Thanks for the help!

I went with the Rennline stud kit. Perfectly happy with it.

I keep a couple extra in the glove box
Mine are apex from www.track-studs.com I have had them on 2 cars with no issues (knock on wood) |
I use track-studs by Apex as they have a nice bullet nose for easy wheel changes

i purchased my studs from CDOC however they did require slight machining before installation...
both my RS porsche have had them installed and they are fantastic. I keep four spares (one for each side) and have yet to need them.. All the above sound good. Just avoid titanium. |
I went with the Rennline setup and have been very disappointed as 4 of them have broken! The first one I just assumed was an anomaly as it broke when I was torquing them. It just sheared off when I put a torque wrench on it. The wrench was set to 96 ft/lbs and the stud just gave way like melted butter. Very disconcerting!
When I wrote to Rennline, Tom responded and asked if an impact wrench was used on them. I told him I never use an impact wrench to fully tighten my wheels. I do use one to take the nuts off, and I use it once I have the nuts started by hand, but never to fully tighten the nuts. In other words, maybe 30 or 40 ft/lbs just to snug the wheels up and to save the manual turning of the wrench. Then I tighten them to the torque spec by hand. Usually, this means I get another full or half turn before reaching 96 ft/lbs. This is what happened with the first one that broke. I went around the whole car and got them all snugged up, a couple of them needing a full turn or more to seat, so they were definitely not tight! When I got to this one, I thought I was right at the torque setting and it suddenly felt loose again. Thinking I had hit a burr in the threads, I gave one more tug and it just wilted. Not a sudden crack or pop, but more like taffy. He apologized and promptly sent me 5 new studs. I replaced just the one that had broken and kept the rest as backups. I did at least one more track day with no issues. Then, this past weekend, I went to Barber Motorsports Park and after three sessions, I felt a strange vibration. I limped the car into the pits and what did I discover? Three more broken wheel studs?!? Or should I say missing wheel studs. I had limped in with only two lug nuts holding the wheel on! Tom has been very apologetic and offered me a full refund and he assures me that of the thousands of these they have sold that this is the first time he has heard of an issue like this. In fairness, perhaps I got a bad batch, as all of the ones that broke were on the same wheel (left rear), but I have lost confidence in these and will be removing them. |

Does Rennline provide suggested torque value for the stud installation? Do you remember how much torque you were using when installing the studs?

Rennline did not provide a torque value for the studs. They have a hex opening on the end and I didn't go crazy with my Allen wrench. Just what I could muster by hand. I did use thread lock. In looking at the bullet nose versions, how do they install/torque?
|
Put 2 nuts on the stud and torque on the outside nut.. :)

Apex pro-studs for me. 81mm.

New to this. When and why do you use wheel studs?

Tom was excellent to deal with on all counts and promptly sent me a complete new set. Ironically he also stated I was the first case he'd heard of in the thousands of set they have sold... But really what else could he say! :cheers: |
