well i had a chance to try these at epr on sunday in the dry

. ive got 2 sets one on slim wheels and wide wheels (both with foams in). tried them back to back. i found the slim set seemed to push on entry in the turn and over steer on the way out (could easily change set up to compensate) but on wide wheels they felt really good. had the same level of grip as standard staggers but werent affected by small bumps as with the standard form.
