I also torque mine to 85 with antiseize applied every few months. I've actually never had a wheel stud break or back off on me but I never tighten fully with a gun. Both old car (talon) and Evo have always been on OEM studs though the Evo front has bolt on 20mm spacers.
Ill probably switch that to a slip on spacer soon with extended studs but hard to make a change when its been historically reliable for me.

Rich's axle snaps I think have been due to using remanufactured units after the first one broke. The big lesson is always use oem. Find them used off of reasonable mileage cars. The upgrade alternative is pretty pricey. I have not broken a hub or stud yet. I use arp studs on all four corners and I have two rear hubs that will be in my travel kit with a spare set of ARP studs.

Gutted interior and lack of restrictor put you in XP. You need all interior panels in place and carpet in SM. 6 point cage is SM legal, just don't gusset it to the chassis other than mount points or pass through the firewall on your forward bars.
Do you have your crash beams still? With a gutted interior I would guess those could have been tossed for weight, but they're also required in SM.

Would the next class up be FP or XP?

FP requires running a restrictor plate in the intake. XP does not, so you could move to FP if you added the appropriate sized orifice.
An all out autox car is not going to be track friendly and vice versa. The safety equipment required for track is added weight for autox, and I would not feel safe tracking my non-caged SM car. You have to decide what is your current target, and realize the compromise for the other.
As for what to do to be more competitive... seat time. :-)

Thanks guys for the input. I think I'm gonna try to put the couple of pieces of interior I need back for SM so I can run SM a few times this year. Track is obviously the priority, but it is nice just to drive 15 minutes and get some autocross in every few weekends.
#103
Does anyone have exact specifics for interior parts needed? The rules are very vague on this. If I have all door panels, carpet, dash, heat, aftermarket front seats, is that enough? (so essentially rear seats and everything in the trunk are gone). Is this the correct list of all that is required?
Headlights (high and low beam)
Turn signals, front and rear
Brake Lights
Heater
Windshield wiper/washer (single wiper conversions OK)
Horn
Parking Brake
Interior Door Panels/Garnish
Side Window Raise/Lower Mechanism
License Plate
Reverse Lights
Also, I'm currently running NT01, do I need to switch to a higher treadware tire?

the interior needs to be stock, except for what they allow you to change. in SM you can remove the rear seats, you can replace the front seats, and you can change seatbelts/harnesses. If you install a roll bar/cage you can trim the interior panels to provide clearance for the cage structure, but not more than that.

As far as tires, you'll want something with lower treadwear than NT01s actually. Look at Hoosier A6s. The old me would have suggested BFG R1S's, but having been to Lincoln on them, I know not to make that mistake again.
