My first two track weekends were on sumis with 205 front. They were fine but I was so new I was barely pushing it. You are more experienced so you will be pushing harder, and when you go to a 200 TW tire with 225 front you will really be able to feel it. But if the sumis are free with the wheels... You may as well thrash them on the track
or use that set as your street tires and get RS3 for the other set, what do you have on there now?
