But, both of them are legal for SCCA ST classes. I want to say the treadwear rating for either of those is in 150 range.
On the brakes, it doesn't matter where the parts come from for most of the SCCA classes. For example, the stock classes only allow a cat back exhaust, replacement struts/shocks, and the use of R-comp tires (there could be a couple of things I'm leaving out, but that's the gist of the rules). Any mods beyond those, and the car is in a different class. As another example, a friend of mine had a 1989 Toyota Supra Turbo and the only mod was a 3" downpipe. That one mod moved him from a stock class into E-street prepared. ESP allows many more mods than the stock classes, and so his car was way outclassed.
The point of all this is that you really need to sit down with the rulebook and see what is/isn't allowed in the class you want to run. Also, bear in mind that Novice is an indexed class, so you're actually running against *all* the other novice cars.
