I recently replaced my worn out Continental ExtremeContact DW with Michelin Pilot Super Sport tires. I don't know how they are at high speed (say +120 mph) because our local track doesn't have long straights but traction out of corners is phenomenal compared to the stock Pirellis and Contis. They take the heat better too, more stable over the length of a lapping session. The car is a 2012 Mustang Boss 302. Sizes are 265/35/18 fronts and 285/35/18 rears on TSW Nurburgring 18" x 9.5" wheels at all for corners. All wheels are downsized in diameter from the stock 19" and the front wheels are wider compared to the stock 9" fronts. Front tires are also wider, compared to the stock size which is 255/40/19. If you're considering pulling the trigger on a set of Michelin PSS's to use on the street/track, I highly recommend it.
Last year, I picked up a 2009 Lancer Ralliart to do a long term test with it as a dual duty track/daily. One of the first things I knew I was going to do was put a decent set of tires on it. The car came without OEM wheels which was actually good because I didn't have to hesitate about getting a good set of aftermarket wheels to support going wider. Thankfully, my friends at YST Auto Halifax set me up with a great set of Superspeed RF03RR wheels. The Wheels I had never even heard of Superspeed but I trusted the good folk at YST Auto who mentioned some customer cars running on track with them. These wheels are rotary forged which is basically a prerequisite to be taken seriously in this market populated by companies like TSW and Fast Wheels. The wheels looked like a high quality, well finished wheel and each had a "QC" check sticker on. Just for appearances? Maybe, but I found no defects. The wheels seemed easy to balance (didn't need many weights) and at 18.1 lb. f
