gears and tires are a big help, these cars are pretty light and need all the help they can get. im assuming you've got a 3.8, or a 307.. in either case, a motor swap would have the most impact, unless you somehow turbo the 3.8, but at that point you would swap in a motor from a grand national, then you get all the correct parts. i myself also have an '88 cutlass supreme, that i swaped in a 455 on a th350 that i rebuilt, it was definitly an improvement, although i had to remove the spare tire hump in the trunk, and repostition the gas tank so exhaust could run through on both sides, without resriction. not a bad car to start with though, pretty much the pinacle of g-body hardware, being the last year.
