In reality its probably somewhere between 15-20% stiffer. Feels great when cornering, but you definitely feel every little bump on the road. I'm wondering if regular radials would feel the same compared to the run flats?
Def let me know after a few days of driving it...right now wife thinks msport is like so luxurious which means I think it could be stiffer ...using my mind only I feel it could be ten percent stiffer without wife caring... But combine that with lower series tires and you get into trouble (I'm on stock 18)... I don't want it to feel like a sports car, but feeling like a sports sedan is okay if that makes sense.
