I would go OEM or KYB. I actually did this job on the same gen using the OEM shocks as a complete unit (bearings, bushings, spring, etcetera). I did not get an alignment afterwards and it's been years since with no problems tire wear or handling-wise.
I went OEM to OEM though, if you don't go OEM and the dimensions are off I can see that changing things. I bet it won't make that big of a difference though.
Frankly if I couldn't go OEM I'd go KYB or not do it at all. Don't cheap out either, there are some really [censored] brands out there like Sensen. Google "sensen welds broke" to see what I'm talking about. Don't take a chance on this stuff.
