i got a 2003 mach 1 what are the best upgrades for speed and drivebility and what are some good tires for it

Mach1

The only upgrade i have now is a catted slpxpipe, with the stocker catback i think its a great combo. You may also want to check out a good cai or rai. A php intake spacer should give you a nice boost. Check out mach1review.com they have many other products. As for tires i have my eyes of bf goodrich kdw's.
