Yeah you can compare one suspension kit w/ another, but add addition parts to the mix= tubular control arms/ toe links/ camber arms & even poly bushings & your suspension set up changes. A car equipped w/ a torsen is going to react differently then w/o. Just to throw that in. So, I'd ask, How far are you wanting to go?
Introduce Mr. Torsen to the mix
