How did the Q2's work for you? I was at CMP all weekend and my Diablo Rosso's never slipped. I have done a track day before with Dunlop Roadsmart's and I was impressed with them. But I must say, the Rosso's really impressed me.

 

Sorry I forgot this post exisited. Yes, the 180's wold turn in quicker...but the 190's stick better. For my F4i on the street, I've ran both 180 & 190, and I'll only stick to the 180. But the track, I've done both, and I'll stick to the 190.

To give you an idea where we're at.... the 190's were spec for the AMA. Some are even using 200's now.
