who did a stud conversion on their M3/M4 ??

[e85m4]

Is it safe?? What brand did you get? Im looking for more info and i think it would be a lot easier to swap wheels with them on !!

Thanks

I don't think you need to torque according to how it structured, just hand tight them. Use red loctite instead of blue as you don't need to take stud off.

Lug bolts and studs/nuts are wearable items so proper care must be practiced to ensure their longevity and service life. For a street car, I would say every two years would be a recommended time frame. If you are racing, it is good practice to replace wheel bolts studs/nuts every season or every other season based on frequency of track events.

Some things to note:
Washing the car - when finished, drive the car around the block to remove any excess or sitting water in the lug bolt holes.
Living in snowy climates - It is good practice to apply a small amount of anti seize onto the nuts to prevent seizure.

Samesies. Very happy with them for rapid fire wheel changes.

Blue loctite is recommended (and included with Macht Schnell Stud kits).

I'd avoid red loctite. It makes it near impossible to remove the stud later without destroying it in the process, as well as chasing threads to make sure everything is cleaned out.

Thanks for the picture Do they come with lug nuts?

I use these:

Used blue locktite and a torque wrench; very easy install.

In this video I show you the Motorsport Hardware Stud Install. I love them I also have a set on my E30.

I've used Motorsport Hardware, Mach Schnell, MRG Titanium studs and now I'm back on another set of Motorsport Hardware with Project Kics nuts.

My only feedback is what not to use. Don't buy titanium studs. Don't buy Motorsport Hardware Clearance stuff.

what length stud if no spaces?

[jacobe92]

I have the 80mm MSI Racing. This company claims to provide studs and bolts for NASCAR teams. Good enough for me.

do you think the 70 mm would work?

75mm is good for up to a 12mm stud. 90mm for wider.

[ShoNufff]

I'm running 75mm studs, definitely a lot easier to take your wheels on and off. One of the first things I did when I got the car.

Just FYI...

Keep in mind that the MSI studs convert the F80's M14x1.25 thread pitch to a M14x1.5 thread pitch. This may or may not be something you want. Personally, I prefer the 1.5 as there are more nut options.

Some people match stud length to what kind of nuts they're gonna use. If you're gonna use the normal short nuts, 72mm is perfect IMO. If you're gonna go with a tuner style nut, perhaps a longer stud will look better. It's really up to your taste.

[Irma the imola red M4]

just ordered :
macht schnell stud conversion kit 14mm thread pitch & 90 mm stud length ...
will be installing h&r spacers not sure what mm spacers yet hence the 90mm stud length

Ding Ding Ding. You are correct

Never use RED loctite unless you like to play with torches every race season or 2yrs. Even the NASCAR grade studs like MSI, they rust with weather / wear and used with antiseize.

The manufacturers who recommend RED loctite has very good lawyers writing those installation instruction to prevent a lawsuit. It idiot proofs the install process for those who cannot follow proper torque instruction and the wheels fall off which could hurt someone (or themselves). BLUE loctite is fine and you don't need much torque on the stud itself. Follow the recommended "lubricated" torque for the stud and follow BMW's torque spec for the nut. With anti seize on the nut thread side, 95ft lb is good. Remember, with antiseize you should reduce the torque by 20% since it's considered "lubricated torque spec."

Would this length work for 19'' 437 wheels without spacers?

I am using the apex 75mm ones

I used the Motorsports Hardware 75mm stud kit on my wife's 2011 335is Coupe. I used the APEX 75mm stud kit on my 2016 M4 just because it was easier to order them with the APEX track wheels. I just ordered the same wheels and stud kit for my wife's new 2018 M3.

On the 335is and the M4 I used Loctite blue and torqued the studs when I installed them and I'll do the same for the M3. I torque the nuts to 85lb./ft. for the street and 90 lb./ft. for the track, per the APEX recommendation.

Make sure you order an extra stud and a couple of extra nuts as spares. Better than downtime.

Definitely what he said . . . . I learned that the hardway.


Are you changing the apex studs every year?
