Suspension upgrades are a great way to make a car feel faster. Not having to slow down as much for a turn is really a key to maintaining speed instead of having to build it.

On the engine side, start with intake and exhaust. You probably won't set off car alarms with a V6, and be careful which one you choose; a V6 sometimes sounds like poop with a really open exhaust.

If I had it, I'd do cold air intake, headers and exhaust, and lowering springs with Bilstein shocks. Consider better tires and ECU programming, but all of the engine mods together will probably get you 20hp max, so weigh the cost versus the benefit. If you're serious about performance, don't go nuts with 20" rims. 16 or 17 is about max on that car before you start going too far and losing handling

Keep close tabs on cost as well... it won't take long to spend as much as it would be to upgrade to a v8 stang.
