Predictable handling, long life, and lower cost are. There are a lot of expensive, fast tires. Some give decent tread life. Some are marginal on the street. Others with hands-on can chime in, but I understand the RS4 has the longest life, lowest cost, and most predictability. My guess is sticking with 245/40s is best; the 255s may have some clearance issues depending on fender work and wheel offset. STR cars use 255/40s on 17x9 wheels with +60. I believe the RPF1 is at most +45.

Fenders are rolled and tabs relocated, I originally ran 245's out of fear for my fenders, but havent had an issue over the past two years with them. I figured when it came time to replace the Z2's I would move up to a 255, I was nervous that the suspension would allow for too much travel to safely run the 255.

The car is transitioning to a track day car, with one day possibly using it for competitive events. I didnt want to just jump in and set the car up for something specific yet, I'd like to get some experience under my belt first. I would eventually like to end up in a TT situation, maybe in another year or two
