The Eagle F1 Asymmetric is a pretty good tire ... it actually out performed the PS2 on our test track when we tested them head to head. When the results we calculated the PS2 ended up winning the complete test because of it's combination of ride quality and performance. I have no doubt that the PS2 "C1" would out perform the Eagle though as it's a stronger performer than the 'normal' PS2. The Eagle is not available in any Viper sizes so, I'm not sure why we are discussing it here.
