Gents,
I recently purchased a set of APEX 75mm Racing Studs and wanted to share my install experience.

First off, run to your local parts store and buy a deep well 1/2" drive 17mm socket because your standard sockets won't clear the studs. Also pick up a torque wrench if you dont already have one with a allen hex head driver set and a bottle of lock-tite red thread locker.



Its hard to mess up a stud kit but I chose APEX Racing's offering due to their heritage in track purposed/worthy performance parts. I couldn't have been happier with the quality of the hardware and at a great price with lightining fast shipping!

Install is fairly strait forward, spread a dab of the red thread locker on the threads and screw them into the hub by hand.



Next get out the torque wrench with allen head driver and torque each stud down to 30 ft/lbs or 360 inch/lbs. this is a very important step because you don't want your studs coming out while you are driving from not enough torque or snapping under heavy load due to too much torque.



Give them a few minutes to allow the thread locker to set and re-mount the wheel using your 17mm deep socket wrench. The end result is a very GTS-esque appearance for your M3 as well as the added benefit of easy mounting of the wheels now that they have more than just the hub to hang on.

Im very please with the end result!





*note APEX has longer stud offerings for those with stud length envy

Looks good. Interesting that Apex specifies 35 ft/lbs. of torque. I believe Turner recommended 16 ft/lbs. That's quite a discrepancy.

I have the same studs. I would not use them with 15mm spacers. They are too short. Not enough threads are engaged. You front wheel does not look safe given the stud length that sticks out. You need 90mm studs for 15mm spacers.

I double checked and 30 ft/lbs is the recommended torque spec for the studs

Good catch, I got these along with my EC-7 wheels that I am planning on using this summer (without spacers). I have already taken the spacers off and posted new photos!

Still a big discrepancy. Wonder why?

You put way too much thread locker on that stud in the picture. Also for longer studs, the double nut method is the preferred way of installing them. Beautiful photos though. Skills, you have them.

Thanks! With all the critiquing comments you would think I did something more complicated than screw some studs into my hub!

Just a heads up... you don't have to use red thread locker to install the wheel studs. Blue (medium strength) is completely fine, and furthermore lets say you buy 75mm studs and then you decide they aren't long enough, if you used red thread locker to install, you're either going to fight with double nut method for removal or a blow torch to get them out. Red thread locker is pretty close to permanent. If you have any doubts in you're mind, I recommend you go blue (it's what's on my wheel studs). It's more then strong enough.

Turner recommends and includes red with their studs. IMO, the studs are one thing you really don't want coming loose. I'd rather have to fight hard to remove a stud in the cozy confines of a garage than lose a wheel at high speed on the highway/track.

They're a convenience item, especially for people with multiple sets of wheels / change wheels a lot. A good example is a dual duty street and track car.

Studs make it way easier to install and uninstall wheels because they support the wheel during installation rather than having it just rest on the hub (the wheel could fall off if you're not careful). Also, it makes installing spacers a breeze because there's no need to line up all the holes perfectly. The studs do that for you.

Also, if you run spacers with one setup and spacer free with another, you would need a set of lug bolts for each setup. IIRC the 75mm will work with anything up to a 12mm spacer and 90mm will go up to 20mm spacers. Therefore no need to have multiple sets of hardware.

And they do look cool

I installed Vorshlag 90MM studs this AM. It does make installing wheels and spacers easier.

I used a thin vertical bead of red loctite as well. I wouldn't have done it but since I'll be changing wheels so often now I thought it would be a good idea. Less wear on the OEM Hub too.

I've had my wheels off and on again about 8 times in the past few days…the thread locker helps keep the studs from getting worked loose from high usage. They have really helped out by preventing the spacer/wheel/lug dance every time I try to put the wheel back on

great mod and even with these on you will still knock your BBK occasionally, these just really make that type of contact a minimal as possible, they look awesome, and just more practical imo, plus buying new studs is cheap, super easy to install and change if need be.... also they are very strong.....

I agree, its a subtle mod but true enthusiasts will notice and appreciate it!

when installing the studs on the front wheel how do you keep the hub from spinning when torquing down?

Torque them down as much as possible then mount the wheel and partially lower the jack then torque them the rest of the way.
