I want to gather and further discuss technical details regarding the wheel studs. In my case I want to place 10mm spacers, the car is a regular GT. So far I found couple of topics:
https://www.mustang6g.com/forums/threads/installed-10mm-spacers-and-longer-wheel-studs.56677/
https://www.mustang6g.com/forums/th...isit-and-a-screw-up-for-entertainment.159924/
that describe particular installations, but I'd like to have a general info about available options.
OEM front studs BCPZ-1107-A have these parameters:
Total length: 55.58mm
Under head length: 50.29mm
Shoulder length: 13.76mm
Knurl (shoulder) diameter: 15.88mm
Also I measured the available thread length on the stud when the factory wheel is on (available for lug nut): 20mm, that corresponds to 11 revolutions.
So, assuming that we want to place a 10mm spacer, the ideal new stud should be 10mm longer: 60mm of under head length, assuming that the thread is through all the length. Longer studs may not fit inside the closed lug nuts, shorter studs may compromise the security aspect.
Based on the other posts on mustang6g and across internet there are these typical options:
Dorman 610-435 - M14-1.50 Serrated Wheel Stud - 15.96mm Knurl, 57.94mm Length, +7mm thread length <- a little bit short, but good price
Dorman 610-631 - M14-1.50 Serrated Wheel Stud - 15.90mm Knurl, 77.21mm Length, +22mm thread length <- expensive, positioned for GT350/500
Ford FCPZ 1107 A - OEM for an F-350, M14 1.5, the same knurl size, +10mm length <- OEM replacement, available on eBay, cheap
Worth to point out that a stud with large head doesn't fit because of ABS ring. That's why Dorman 610-631 has cut off head on one side and Dorman 610-435 has small head.
At this point what I'd like to discuss - the other options for studs. If we go to Dorman site: https://www.dormanproducts.com/gsea...c=Metric&Thread Size=M14-1.50&start=0&num=100
there's a lot M14-1.50 serrated studs with the length for any use-case. For my case I'd pick 610-004 over 610-435 since it has 59.77mm length, or 610-783 of 63.6mm length. And if I'd like wider spacers, there are plenty of options for longer studs.
What's interesting to me so far - the material strength (bolt grade). Dorman 610-631 for GT350/500 is of grade 10.9 - we assume it's the perfect choice. 610-435 doesn't have info regarding the grade on the website, 610-004 has grade 8, and 610-783 has grade 10.9. So in this aspect 610-783 is the preferred option (and the price on Amazon is just $80 for 10 studs).
Interesting if anyone has more info or expert opinion on this topic, will be glad to hear that.
