Got rid of those damn run-flats and replaced them with 255/35 & 285/30's on HRE FF01's (thanks Nate at Vibe Motorsport
). Took a 200 mile round trip down the NYS Thruway today and the ride quality is 1000% better than stock. I should've spent this money 2 years ago. Those god damn run flats are loud and harsh and I'll never put them back on my car again if only because of the added cost differential. The car is quiet, rides smooth, you don't get jarred over the tiniest of imperfections and it's just a lot nicer feel through the wheel. I should have weighed the stock wheel/tire combo vs. what I replaced them with. Even with larger tires this set-up has to be 10-25 pounds lighter per corner. Nothing but positive things to say about this change. Those HRE's are pretty bad ass to look at too if I don't say so myself.
