The increased stagger isn't optimal -- and I'd love to run 275s in front --but I need the increased rubber in back and I'm able to get turn-in with toe and camber.

I would think the increased stagger would be ideal with so much added power. Last year, I could not put the power down with RE71r 275's on the rear after my tune which added about 150+ ft-lb. Second gear would even break loose in straight line acceleration. That is why I decided to experiment with wider rear rubber, and will also run about 0.2 degrees less negative camber in the rear which should help the car rotate.

I ended up going with the Bridgestone RE71r's in 255/35-19 front 285/35-19 rear. They are getting fitted today, followed by alignment. Your experience in OLOA may effect my purchasing decision next year.
