Cool,I do have the silverado extended studs.
What studs will fit the Camaro front and be long enough to use 30mm spacers?? Any part numbers? |

Yes I was looking at those arp studs that are 1in longer than stock and your right they are advertised as being able to handle 25mm spacers.

I really, really, REALLY hope you didn't torque any of those 12mm lug nuts down to 140 ft*lbs. Norm

I probably have 3-4mm of clearance from the inside tire to strut.
My rear spacers with studs are 14x1.5 so I did 140lb tq on all the rear. With the front spacers have 12x1.5 studs so I did 120lbs but I'm thinking of backing them down to 100lbs. What do you think ? Here is a diagram I got from tire rack. Although based on this 140 lbs is over tqed for our 14x1.5??? Eric |

I'd also agree, that table is kinda useless. In addition to what's already been said, grade plays a big role in torque capabilities and isn't even mentioned. Number of turns is also odd. Typically 3 threads minimum is the general guideline (about 75% of the total load in fasteners with more than 6 threads), but 99.99% of the time the first 6 threads will carry 100% of the load. Some race teams definitely use less than 6 threads/turns on their wheel fasteners, and I'd even imagine some OE's use less than that. I've even ran my own car with 3 threads engaged on the front wheel lugs for a couple of track days and they were fine. Was personally sketched out by it and swapped to truck studs to get a few more threads engaged after 2 track days as I prefer safety to being cheap/lazy, but trying to get 8 to 9 is definitely overkill.

Yeah there not calling out the thread pitch which makes a differance in torque values.

After the autox everything was great with tire fitment, no rubbing anywhere. No spacer issues. They definitely handled well and much more grip laterally and much more forward acceleration grip compared to my BS set up (19x10 w/ 305/30/19 supercar 3 & 19x11 w/ 325/30/19 supercar 3)

I have three cars that use 12mm studs. Two of them call for 90 ft*lbs, and the Mustang calls for 100 ft*lbs. I'm 99% sure that the driver side front lug nuts on the Mustang were torqued significantly past 100 ft*lbs once (pretty sure it wasn't by me). I don't know if they were run down to 25 more or 50 more, but I eventually lost the driver side front wheel in a 50 mph 1+g right-hand corner on the track. Could have been only 5 sessions on them after being overtorqued, could have been twice that many, I just don't know. Norm

CamC is a really cool class.

I adjusted the front lug nuts (wheel to wheel spacers to 100flbs , they are the 12x1.5)
I am going to order front spacers with 14x1.5 studs in the near future What are other mods that make good gains for CamC? DSC sport controller? Camber plates? Eric |

Good to hear no rubbing, I'd still be concerned with a good apex curb clip and would like to know what it looks like at full compression. Clearly not an issue for autocross or street besides paint chips haha.

Right, it is a autox set up for now, so no curbs if things go to plan on the autox course.
