Nice looking wheel and very low weight and OK price point.
BUT, I recommend looking into a few things, considering some, etc....
Search for specific issues like cracked wheels for that particular one as some Rota wheels have tended to do so.
Going to lower weight wheels then adding some of that back in the tire and the larger the diameter the more the effect, moving the mass further out, it will add more stress on the brakes and acceleration will be decreased which can and likely will negate any gain in overall grip from a bit wider tread.
The taller the tire the more it effects the gear ratio so it can lead to lower acceleration numbers as well but for autocrossers being able to stay in second gear instead of a quick shift up and down and less feedback can also negate any gain in added lateral grip.
As stated many times look at the weight and diameter but also the actual section width and tread width as those last two can be hugely misleading if you go by the sidewall numbers, some 225's are narrower than some 205's I have seen and there is a 195 that works great on an 8" wheel, things can be that far off.
I know I keep talking about this stuff on many threads and the main reason why is some have not seen the other posts and are new or not well informed when it comes to such matters and the simple fact that we cannot ignore physics, if we place style over performance there will be a degradation to the car and wheels and tires encompass all areas of performance, ride and wear and tare on the chassis.
