I put 275s on the rear, BFGs to match the fronts. If I would have needed a the fronts swapped I probably would have switched to Cooper Cobras. They look to be more "square" and less "balloon" So they probably would have had better clearance.
I really haven't had the car out much recently so I decided to take it out the past few days. Today I took it through the park and ended up missing a turn. The ride ended up being about twice as long as I expected and I ended up going through some twisty roads I wasn't expecting and up an extended hill. I definitely should take it out more often!
And with QA1 shocks on all 4 corners and no tire rub it was a very nice ride. I still want to replace all the rubber in the front suspension over the winter, but for just ordinary street driving it's more than acceptable.
