15",16",17" or ??? for auto-x rims/tires?????, wanna be "close" to competitive in QM Options

Since I don't want to be the laughing stock in the class I'll be placed in (QM I believe, Street Modified)

I figure I will have to step up to the plate and get a second set of rims and tires for auto-x (time trialing sooner or later...okay, much later)

car has stock fenders, I do not want to add flares, but I am open to the idea of rolling the fenders or pulling/bumping them out slightly

Current rims are 16x7 under stock fenders running 205/45/16's
(40mm offset rims)

Running in Q-mod, you are gonna have an immensely tough time being anywhere even near competitive. QM has cars like "Cujo" in it--which is either a 964 or 993 platform with a 3.6 or 3.8 liter motor and boost adjustable up well over 1.0 bar. The car is not just fast, it's "holy fucking shit!" fast. The only hope you could ever have is on the tiniest and tightest of autoX courses. And even then, if there's any kind of straight you will be dog meat. (Pun not intended.)

I believe that the other QM cars, while not as monstrous as Cujo, are still going to be able to apply the HP hammer to your head and walk all over you.


If you want to be competitive, then--
Get the smallest-diameter class-legal wheels that you can fit over your brakes. If 15s are not required, then run 14s at the largest--13s if you can make them fit somehow. 7" wide, obviously. Run cantilever slicks, and make whatever fender mods are needed to run them.

Slicks are made in a variety of sizes. I doubt you'll have the same kind of problems finding slicks for small wheels as you will in finding decent street rubber for small wide wheels.

But pretty much, you're SOL. My real answer is run whatever wheels and tires you want, and to hell with the results. You'll place where you place, and it will be fun. If you need to be "competitive", run the C2 in the stock classes. And put in a whole lot of seat time.
