Update.
Over the offseason they updated the rules to allow up to a 315 tire for naturally aspirated front engine rwd platforms. Tires got here last week so I spent the weekend working on the car to get them to fit. Now running 315/30r18 Advan AO52 square.

Biggest change was having to give up the lower ride height. A worthwhile sacrifice for nearly 2 more inches of rubber front and rear. Cant wait to see what it does on course.
