I bought a GR Corolla last January, planning to have some non-street fun with it. Kinda waiting to have some miles on it, now has about 3K miles, so should be good to go for next year.
I have RE71RS on the stock 18" wheels for autox and possibly track. (I'm an old guy, used to do both a lot, but not for about 20 years or so...)
I have DWS06+ on 18" silver Enkei TS-10 for street use.
I loved rallycross many years ago (actually, that was before it was even called rallycross lol) in a 323GTX hopped up with HKS stuff to keep up with the Eclipse and Talons. Lotsa fun. (A "dirt autocross" was newsworthy 30 years ago- won annual KY event 3 years in a row- covered in both GRM and SportsCar, see below.)
Anyway, the GR is pretty low, but Eibach just introduced GR springs in low, lower, and raised spec. I bought a set of the taller springs, which will lift the car an inch or so.

Which I know also moves me out of stock class. I doubt I'll be competitive with fully-prepped Subies, but that's ok. Objective is to have fun.
It's tight, but some 17" wheels fit over the big front brakes.
Some questions:
1) How bad would it be to just start with the 18" DWS?
2) If I go to 17, snow tire or rally tire?
3) Size? I think increasing tire diameter an inch should fit ok. That would include 215-55-17 and 225-50-17
4) What's best for keeping the tire seated on the bead? Narrowest wheel? For example, 17x7 better than 17x8?
5) Do you want soft sidewalls for more compliance for bumps, or stiff sidewalls (runflats if available?) for resistance to debeading? (Is that the right term for the tire unsealing and flattening in a millisecond? Had that happen once on my 323GTX with 14" wheels!)
6) Any other thoughts/suggestions/comments?
Thanks!
