I want to replace my wheel studs with titanium studs on my performance+ Model 3. The only information I could find about the existing studs is this: 14X1.50 Thread. Wondering if anyone knows the other details needed to find a suitable replacement? The attached image is an example of the details I am look for...

I'm going home!
Lots of work for little gain TBH. But the companies that make wheel spacers for us prob have that info. Or knock one out of your hubs and measure it

Yes. I know its almost nothing. But reducing rotating mass is important to me.
Wheels have been replaced. Rotors have been ordered. I really wanted the carbon ceramic, but the cost was so high, I just didn't feel right about it. I ended up ordering the RB 2pc Rotor Kit (355/335) for Tesla Model 3 w/Perf. Brake (P/N 2604 & 2623). They weren't the best rotors, but they were the lightest I could find that weren't insanely priced. I did get your lithium battery kit. I'll will get the Coil overs from you guys at some point. I may end up getting sway bars too, but waiting to see some real world results. Have you guys thought about adding sway bar upgrades to your suspension lineup?
We have about 4 products in different stages of development right now, sway bars just aren't a high priority for us at this time! Try the coilovers with stock sway bars first and decide if you need them.
Here are the measurements from my Model 3 Performance.
A Thread Major Diameter = 0.545"
A' Thread Minor Diameter = 0.5"
B Stud Length = 1.75"
C Spline Length = 0.25"
D Base Length = 0.625"
E Spline Major Diameter = .618"
F Thread Length = 1.0"
A Thread Major Diameter = 0.545"
A' Thread Minor Diameter = 0.5"
B Stud Length = 1.75"
C Spline Length = 0.25"
D Base Length = 0.625"
E Spline Major Diameter = .618"
F Thread Length = 1.0"

Please use the following correction...
E Spline Major Diameter = .618"
The 0.6" measurement I gave prior is the shoulder diameter.

It is the same spec as the late model Ford Mustang, except knurl diameter is off a bit. Mustang is 0.625", your measurement is 0.618". Would the difference caused by compression of a used bolt, compare to new uncompressed/uninstalled bolt?
This one at 3" is a bit long for street, but great for quick change at the track.
WHEEL STUD ,M14 X 1.5 MUSTANG S 550 3 INCH LONG

A few more options that might work.
2.5" UHL (Under Head Length, B)- JEGS 65140: Wheel Studs [14 mm x 1.50 RH Thread] | JEGS
2.7" UHL - ARP 100-7736: Camaro 10 - 17 M14 .500 over stock wheel stud kit | JEGS - The Official ARP Web Site | Kits
2.5" UHL (Under Head Length, B)- JEGS 65140: Wheel Studs [14 mm x 1.50 RH Thread] | JEGS
2.7" UHL - ARP 100-7736: Camaro 10 - 17 M14 .500 over stock wheel stud kit | JEGS - The Official ARP Web Site | Kits
I'm sure that 0.618" is the correct knurl size for 2 reasons.
1) The hole in the hub measures 0.602" which is in the correct range for a 0.618" knurl
1) The hole in the hub measures 0.602" which is in the correct range for a 0.618" knurl
*Per ARP website The Official ARP Web Site | Kits
2) The Titanium ones for Tesla are 15.7mm or 0.618" M14-1.5 x 52mm Knurled Wheel Stud, Tesla Model S-Knurl Diameter 0.625˝ / Wheel Stud Hole Size - Cast Iron/Steel Hub 0.606˝ - 0.619˝
*Per ARP website The Official ARP Web Site | Kits-Knurl Diameter 0.618˝ / Wheel Stud Hole Size - Cast Iron/Steel Hub 0.602˝ - 0.612˝
* If these were longer and had an anti-cross-thread nose on them, they'd be perfect for the track guys.

Thanks for those measurements, this will help a lot of people looking to replace their studs.
If it's really true that the thread length is exactly 1.0"/25,4mm on your studs then this confirms my thoughts that either the European or newer Model 3's have slightly longer studs (I measured 26,5mm/1.043" from brake disc to end of stud on my SR+, that's all thread). As I'll be replacing them in about 2-3 weeks I'll be sure to take some measurements on the studs of my Model 3 as well to be 100% sure. If there's really a difference then many (either European or new) Model 3's won't be able to easily fit those 15mm Bloxsport spacers that are so popular here.

Posted this before. Now after replacing my wheel studs I can confirm that mine have an underhead length of exactly 46mm (1.81"). @Otarpilot measured 44.45mm (1.75") on his. So yes, there definately is a difference in wheel studs on some Model 3's. So please be careful with this, don't just assume that 15mm Bloxsport spacers that many people here on the forum use will work in combination with Aero wheels cause with the 46mm (1.81") wheel studs they will not work!
More info and how-to video on replacing the wheel studs on my Model 3 can be found in this thread:
