"All I'm saying is that the Z06 is better on the race track than the Cobra, stock for stock. Its more expensive because of the superior suspension and because the power is made through normal aspiration, and therefor more reliable." --BlackBird. I agree with you that stock for stock the Z06 has the upper hand---but the only thing holding back the Cobra's road manners----really----is the front suspension. The k-member is its biggest obstacle. But the Z06 has what can be considered an aftermarket k-member in place---obviously thats a big reason that the handling is superior---and it justifies the $50k tag. However, Kenny Brown has developed a front k-member module with coil overs and a caster/camber setup that--easily if not gives an 01 or 03 cobra a bit of an edge. Thats how good that front module is----I know----I have it on my cobra-----and comapring it to the stock k-member--well, its just an insane comparison. The Z06 is an amazing vehicle for the price $---Viper owners are overpaying big time, in my opinion. But the module that I speak of----costs about $1,600 and thats not bad at all when your 03 coupe is only $36k. I don't agree with your naturally aspirated reliability remark. If you have a high quality blower----like an Eaton, Vortech, or ProCharger----and you have Forged internals-----then blower power is as reliable as aspirated power. As long as you service your vehicle correctly----thats a tough argument to wage.
