Just put the A7s on the car. SSRs, 16x6.5/17x7.5 with max-allowable spacer, 2.2ish degrees negative camber, toed in 3/16", plenty of room. One of my rear fender liners is chewed up from who knows what, the tire grazes that, but if it were in normal shape, no problems. I put a fair bit of load on the tires driving around, certainly not as much as they'll see at an event, but no weird noises/issues.
245/50-17 A7s fit, by my definition. Elise, stock bodywork, stock ride height, LSS springs.
