Not all 19" wheels will fit

I'll have to check that out the next time I'm in town. My 8th grade son is already set on going to CalTech and either wants to work on robotics or space related engineering.

@StigsBaldBrother just wanted to verify your wheel fitment. You're running the CF10's with an offset of 56mm and using 30mm spacers. How much room do you have between the wheel and strut? Also is that the tightest tolerance you have? I'm wondering if you could run a smaller thinner spacer and still use those wheels.

I can check tomorrow after work. That combination basically replicates the R front wheel fitment though. I didn't want to change scrub radius of the wheel.

If you're worried about running a large spacer, I wouldn't. One of my many projects on my list is to do a finite element analysis to show the spacers don't change the loading into the suspension.

I'm not worried about the size of the spacer itself but I am concerned I'll have enough threads on my long ARP race studs. The N4SM have a 50mm offset so a 25mm spacer should be fine if I have enough threads. It will be close.

Gotcha. That should work, assuming the studs are long enough. If you want me to do some calcs for the strength of the threads, let me know. I can either tell you how many threads that you need to achieve full strength of the stud or if you give me the number of threads, I can tell you how much load it can carry.

But that's assuming that you know the material of the nuts, which for some reason, is harder to come by than the studs. It doesn't make any sense to upgrade the studs without upgrading the nuts too, at least from a strength perspective.
