You are probably beyond Street class at this point, so your choices are STR, ASP, or SSM. It's too bad too, because really, BS is likely the most competitive place for a 370.

If you want to stay on street tires with suspension mods your only choice is STR, where you'll need 9" wheels and 255 tires. Most people with 370's don't do this, I'm pretty much the only person running an STR 370.

Gomer's recipe is a pretty good starting point for an ASP 370. Personally if I were buying wheels for an ASP build I'd be going 1" wider front and rear (11's and 12's) but to each their own. ASP will be really tough, especially at ProSolos, because you have to beat some extremely well developed and well driven Evos.

SSM gets into nutso territory pretty fast - forced induction, carbon parts, rod ends everywhere, big aero, that sorta stuff. $20-30k just gets you started on a real SSM build.

Can't believe I'm going to say this but I think the 370 can be competitive in ASP, just not at ProSolos. In reality though Pro's don't really matter because of the 3 I did this year ASP never made class. At the Toledo Match Tour, I was only off Bill Rogerson (2014 national champ) by ~1.5 sec and that was almost entirely because I'm just not that good yet. Earlier in the season I had Matt Braun (past national champ) co-drive my car on a similar course on the same site and he was ~2 sec faster than I was. Doing the math, if he had been in the car at the Match Tour he would have won ASP or atleast been extremely close. And this is even with a Quaife diff in the car which is just terrible for autox.
