Obviously I have a lot of work to do to make it STP ready and I am trying to do this on a budget and just add as I go so any advice is much appreciated.

I am currently Looking for some wheel advice as I need lighter wheels and better tires.

Wheel and Tire rules for STP are:

285 tire
10.0 wheel

Ideally I would like to go with a 18 x 10.0 wheel on a 285 tire however I do not know if this will clear the large PP brakes. Looking for some ideas here.

I know I will go with the Bridgestone RE-17R Tires

Have you looked at the ST rules? You have a lot of stuff that is not legal in ST.

The IRS Alignment kit and bushing lockout kits are not legal. Neither is replacing the integral link.

I'd look at the rules VERY HARD before you make any other purchases.

Wheel will clear the brakes - EB PP brakes are non-PP GT ones - non-PP GT comes with 18" wheels from factory.

Why would the IRS alignment kit be no-go? Subframe bushings are allowed, that is the IRS subframe bushing the part goes into and the part is Delrin. Seems to check all the allowed boxes to me.

Same story with diff bushing inserts...so long as they are poly or Delrin.

Agree though that much of the other stuff on the wishlist is not legal (toe links, vertical links, chassis bracing (I think).

Easy button for wheels in 19" is the MRR M350 in 19x10. For 18 there is an Apex wheel that many have used for trackday applications. At the moment the 18" 275/285 tire options seemed too short to me.

BGunn, ditch the Rivals you have ASAP. They unfortunately suck. I used them last year and don't think they were any better than the OEM Pirellis for autox.

I don't think the Ecoboost is legal for STP. V8's only at this point.

On the Appendix A you can open on scca.com it does specifically list the 2015+ EB along with V-6/GT. It might not have been that way earlier this year but it is now.

No, it's listed in STP in Appendix A to the rules.

 

[BGunn]

You guys were correct. I did have some things listed on my wish list that were not Street Touring legal (Removed from wish list)

I called Doug Gill from SCCA and verified things. The only item that I already purchased that is not technically legal even though Doug thought it was silly is the Steeda S550 Mustang IRS Subframe Alignment Kit. At least it wasn't too expensive

I just got started in the SCCA autocross scene last year but I am planning on building the car to go have fun at nationals. Maybe I will look into coming to the packwood this summer

I grew up watching my dad Rick Gunn race in SCCA and watched him go to Nationals in his Datsun 510 back in the 80's and take 2nd. Now my dad co-drives with me and my brother that drives a Honda CRX in STS. We are having a lot of fun.

Welcome to STP! Glad to see some more people try it out since it was looking like Conedodger and I were about the only ones around here.

As another PNWer hope to see you at Packwood. I'll be at the Tour then later Nats.

ryan is tossing around the idea of prepping his camaro pre-nats for STP - so there may be another soon. regardless, he'll be prepping it this offseason - look for it to be classed in STP soon

He's asked me to write a letter in support of it. To be honest, I have no idea one way or the other if it would be a good idea or not. From what I've briefly looked at on national results I'm not seeing it be an outlier in FS so...probably not an outlier in STP either. :shrug: unless I'm missing something and could very well be.
