Other than the obvious, less power ......what are the others differences between the WRX and 2.5 Imprezas ?

Specifically 04' - 05' model years.....

Looks like the have decent rebates and 2.9% financing offer on the remaining 04's and I'm tired of spinning and sliding around when it's wet in the wagon(Protege5) so I'm considering one for a daily driver.

Differences in the brakes, suspension, gearing, steering, diffs ?

Thanks
