Since the tires that came on my car were 10 years old, the first on the mod list was to replace them.
Went with Falken RT615K+ in a 275/40/17 for the fronts and 315/30/18 for the rear. My game plan is run on these for a year or two, and then street use. And then pick up a track setup in 18 square for slicks.
My first track day this year is on Saturday. Pretty excited!
