When I converted my 914 to 5 lugs, I had a local machine shop redrill and tap my rotors, and rear hubs .
I used extended racing steel studs, in 911 thread pitch and size 14x1.5.
When I first put them on , one stud started to pull from the front rotor. I did a quick thread chase at that time, red locktited it and sent it . I have periodically checked it over the last few years ,and has never came loose
Just tonight, I mounted up some new rubber for it and fudge me , 3 studs pulled from the front rotors, at 90 ft pounds .
These were brand new rotors, I probably have 2000 miles on them, and I waited for months for the machine shop to do the job for me too . Im not going through that mess again .
PMB was not selling individual rotors at the time , you could only get them if you bought their kit . Not sure if that still holds , maybe Ill call them Monday
Ill just heli coil all 5 on each front rotor, I hope to someday have some big fat slicks on this and thrash it around some cones again .
I feel pretty comfortable with a heli coil here, what do you guys think ?
