Hello Brian it's finally time to replace the 215/45/17 RE 71s that are on my 17 x 8 6UL rims. The car is a 2013 Club PRHT used almost entirely for Miata club events and autocross; it is not a daily driver, and I have my OEM rims and Michelin Pilots if I need total a long trip. No longer a competitive car just a fun one. Should I go to a 245/40 (which gives me lots more choices and are less expensive too) and will that size even fit without rolling the fenders? The car sits nearly 2" lower than stock with Progress springs and Koni shocks and an autocross-type alignment with a fair amount of neg. camber. It seems the best overall 235 is the Dunlop Direzza and and I'm assuming that is plug and play on my set-up. Is there any compelling reason to go to the 245s? Thanks
