Viper ACR bests ZR1 around the ring

Eh, should have reworded that, Nissan is claming they are sure they can beat the ZR1s time around the track by a good bit after the V-SPEC model is released. Oh well. There all very capable cars with in seconds of each other. Really it just seems likeits a drives race at this point, at least on factory tires. I would be intested in seeingthe same guy drive all 3 and see which is the fastest then.
