American-made in good ol' North Carolina.

I use the 52mm Porsche studs.

20.0012 is the part number for the studs
40.0006 is the part number for the 19mm nuts

Do you have a photo showing how much the 52mm stick out from the wheel, when the wheels on the vehicle?

I'm finally pulling the trigger on studs. I was going to order the Rennline kit but I just realized how much I hate the double-nut install method and am now looking for hex-head studs.

Does anyone have experience with Motorsport Hardware or Schnell Autosport studs? They both have a hex end available which would be more convenient but I can't seem to find out if their kits are of quality.

MRG, no regrets.

I was just curious and checked the price : 300$ for some bolts! These people need to lay low on the smokes...

I wonder if the 90s Civic guys pay the same... that car can definitely benefit from less unsprung weight.

Have you done any track duty with these before? I was looking at them as I love saving unsprung weight but I started walking it back after I saw an M3 that sheared all of them off one wheel (not sure what maker).

Haven't. No time really. At some point I will, but right now that isn't something I can report unfortunately.

Understand its a lot cheaper to use bolts then studs for a manufacturer. For a stud they need to drill and tap a hole then install a stud plus the cost on a nut. For a bolt just drill and tap a hole and you only need one piece a bolt.

A stud costs a manufacturer more because takes more labor and parts. Studs done properly are stronger plus easier to change wheels.carl

I understand the reasoning behind it not the costs. And Honda,Subaru etc guys don't pay that when the whole car costs a few thousands. This is Porsche tax and we all know it. I bet you Lambo/Ferrari guys pay 600$ for the same studs. Sure they're titanium and they're pretty,but overpriced IMO. And it's not just studs,lots of aftermarket parts follow the same pattern.

After breaking some cheaper studs on my 987 I tried MSI and liked them.http://www.msiracingproducts.com/whe...#wheel-studs-2 I also recommend Tarett.

After doing extensive research I decided to take a leap of faith with the MRG titanium studs/lugs. Partly because I'm a weight **** and secondly because I have a natural curiosity for trying things on my cars that others are unreasonably afraid of. I could find only 1 incident on the web of Ti studs breaking and that was on an FI E92 M3 at the drag strip (and who knows how they were torqued and with what). Otherwise it was all old wives tales with no proof. I even saw that competition drag racers have used them for years without issue until the power levels and tire sizes became too much. Hope I don't eat my hat on this one...

I would've paid slightly more for the MSI studs and lugs anyways and some of the other choices either had very little reputation that I could find or too much negative reputation for my taste.

I've changed over to the Ti studs. The 75mm was just barely enough for a 12mm spacer in then front. I'd driven a bit on the road but I have not tested these studs yet on the track. That'll happen in spring 2017.
