My father had done his own maintenance (brakes, wheel bearings et al) on his vehicles --mostly Lincolns and Fords. We didn't have air tools or a torque wrench. He'd use a heavy duty cross wrench socket tool to tighten the lug nuts as tight as possible. So much torque that he actually welded rebar onto the X wrench to keep the shafts from twisting. I'm sure it was wayyyyyyy too much torque but even then, we never broke a stud or stripped a nut on those inferior Ford parts.

Add me to the list of people with broken Apex Pro Series studs. I see I'm not the only one who limped a car in on 2 studs.

This is after 4 DE weekends, no wrecks, 17ft lbs into hub, 94 ft lbs for the wheels.

Emails to them have thus far gone unanswered. (Update- emails were replied to. I missed the fact that they were out for two weeks.)

Emails went unanswered because as mentioned on the website we were shut down for 2 weeks. I will reply to your emails that I see now. Also, please be fair, most of the posts on RL in this thread and others about broken studs are from other manufacturers. They all break under certain conditions which I will discuss with you via email.

Fair enough, I've been on the site multiple times and could have missed that.

a couple years ago tried to buy some studs from apexcomp (not to be confused with clarke from apex racing...) and got literally NO help when a couple questions on fitment were asked. Called MSI and they were super helpful, bought from them. Their products are on all my cars.

Looking to get some wheel studs myself but I have an interesting problem to solve. The current wheels I have use tuner lug bolts (Avant Garde Ruger Mesh). The wheels I get for the track will most likely not require tuner lug bolts. Is there a wheel stud that can handle both wheels? Is it just an issue of getting 2 sets of lug nuts (tuner and "standard")? ..or am I up poopoo creek here?

Any help would be great!

Only the lug nuts touch your wheels (once tightened).
So get yourself a set of proper 14mm radiused lug nuts and your track wheels will fit.

Slightly late reply/request - link to where to get them?

The last thing I want is to have a horror story from what I've read about the rennline studs (yikes).

Thanks!

Google "H&R 1454005". Tons of places sell them. These are 40mm which works with every wheel and will accommodate 7mm spacers if you need.

Bringing this thread back up, getting tired of changing wheels using a stud hangar and the oem wheel bolts. What are THE wheel studs/nuts to go with these days? I found the H&R's on amazon but don't know what lug nut to go with or what length.

997.1 NB GT3 running 18" track wheels without spacers.

The general consensus is that Rennline, Apex, MSI, are all fine as long as you tighten to 118ft/lbs.

Does anyone have a kit with studs and nuts? I did a quick search and just saw individual part #'s. Also do I need 60mm, 70mm or 80mm?

See post #84. Use OEM steel lug nuts from air cooled cars.

CosmosMpower

Thanks, is 40mm long enough? I see some posts on here about 60-80mm studs. Where does one buy OEM steel lug nuts from air cooled cars? Have a part #?

powdrhound

40mm is long enough, otherwise I would not have recommended them. With thick E88 centers, 40mm studs will stick out about 10mm past the end of the lug nut. You want them to stick out more for some reason, go with longer ones. You can get the lug nuts at the dealer or ebay. Your choice...
