I borrowed an 03 Mach1 for five months and that is the same suspension that's in the kit. I don't think that the handling would be a whole lot different in a 94/95. I loved the Mach1's motor and exhaust note, however, it was not nearly as good as my current setup. I have much less body roll, brake dive, and a ton more confidence.
If I had only driven the Mach1 a couple times, sure I might just be nervous about the car. However, I had it for five months, so I was very comfortable with it. Almost bought it too, but realized that I'm am merely one good built motor away from having something better (and mine's paid for).
All that to say.........you can spend just a little more and go with a more agressive suspension that is still comfortable and not too low. Get just springs and shocks/struts, then do the sway bars a few months later. Maybe do the arms in the rear a few months later. Subframes are an absolute must. MM has a K-member brace that is nice, too.
