gonna give your viper a shot ASAP boss, it'll be interesting to see how the lower powered versions compete, but man would these cars be fun to race head to head! still searching for my second wangan car, thinking zz2 since i know it'll do the highspeed, it's a challenge to tune i've never mastered, and we've allready done MR and FR so AWD would round out the useable layouts (please anyone, give me crap for ignoring FF as a 1000hp capable platform). i'm tempted by the nardo and the cadi supercar as well as the saleen s7, though i don't think any of those break the 1000 hp mark.
i've attempted two other cars, the nearly forgotten corvette zr1 and the awd ruf, both didn't work as planned, the ruf with debilitating power understeer, the other with simply not enough power for this class of car, it's a very selective and fun class to build and tune.
did you ever get an nsx to try out? i'd like to hear some customer head to head comparo's!!
