The Cien p*ssed me off in the big leauge races. It was a good car to easily win races. I liked it at first, giving it a racing wing since it was a pure racer. But when it came to the bigtime America racing series, this car p*seed me the hell off. Tune it as much as you like, it won't give you anything when you sell it. Waste of a car if you ask me. You're lucky you could blow out the competition against Honda Beats at Motorland with it.
It's basically a streetcar with a big motor, alright handling, but won't help you win the big races. I was actually disappointed with it, not to mention I'm not a real big Cadillac fan. I'm sure with all that power and performance, it could at least put a Panoz Esperante on the trailer heading back to Georgia.
So any modifications to make it a pure race car would be certainly welcome. Just look for springs, maybe a few engine upgrades, grippy tires would also work, just about anything you can do to make it a pure race car than your average concept car would make this machine shine.
