General consensus on wheel sizes?

As with most things, it depends on your usage. if you're hard core about Autocross, 17's will probably be best. Will you be doing serious track days, or just spirited street driving/moderate track running? 19's should give slightly sharper steering response, but I don't know that ultimate grip goes up over 18's, which to me have great response, but I've never driven on 19" wheels.

I would suggest test driving cars with each wheel size 17-19", then decide which suites you. The OEM 17" wheels/tires are narrower, so will have less grip than the larger sizes.

Having said that, I think 18's are the best for me, though I would like try a car on 19" wheels.

P.S. Oh yeah, The highest ultimate grip will come from stuffing the widest tires/wheels possible under the fenders, without raising the ride height, which you would actually want lower, regardless of wheel diameter.
