If our wanting to run slicks I reccomend hoosier a6 295 30 19 rear and kumho 245 35 18 fronts. We tried the hoosier up front but without enough camber they cord quick. If you plan on running a mix of autocross and track I would try nitto nt01 235 40 18 front and toyo r888 295 30 19 rears. But for autocross the michelins dont really get up to temperature enough and dont not reccomend them
And if you decide to go with a street tire to drive the kumho xs 245 35 18 and 285 35 19 we found are great for concrete and all around a good tire
