in a str8 line with equal drivers the S2K will win... in cornering ability there's no comparison...S2k all day. road racing, autocrossing, drag racing, you name it, the S2k does it better than the Z. the S2K is lighter, more agile, better balanced, superior engineering, one of the best 4cyl motors on the face of the planet, and just a better car. get the S2K...i just bought a 2006 Mitsubishi Lancer Evolution IX MR. the sport compact to end all sport compacts, but there's still something about the S2k...that's why im planning to buy an 04 i found later this month...so i'll have the EVO and the S2K
