This car runs best on the "Power" tracks - basically those tracks where you'd expect the muscle cars to go well. It isn't as fast as the "missile" Chevelles seeing as it only has 444bhp and is a heavyweight. But, it can give some of those Chargers a run for their money, even with it's office block style drag coefficient. (I run with TCS off, so this isn't one of those cars where you will find the wheelspin too much of a problem - just use your common sense with the throttle and you'll be OK) The main advantage of this tune is that it has gradual oversteer rather than the "snap" oversteer commonly seen on muscle car builds, and so is probably a good place to start for someone wanting to try the lower class muscle.

I've had it posted up at Muscle Inc. for a bit, and of those who ran it, it seemed to get a favourable reaction. This included:

"It easily destroyed all my previous best laptimes on any track with even a small straight." - Backfire NL
"It is so well balanced that even without TCS, when it steps out it is slow enough for you to catch it." - sk15kev

Fingers crossed someone else enjoys it too
