Yeah, sound deadening is a good investment for a street car - one of the first things I did.
Still, with the R888's I sometimes have to peer over my shoulder and make sure Valentino Rossi is not in my blind spot!
I use Goodyear eagle F1A2's on the front. Really good grip, sticks in the wet. Feels like its shortened my braking distance as well, actually feels better than new rotors and pads for stopping.
