i did the same thing with my car since i needed tires. getting lighter/wider tires will greatly help your performance along with the looks of the car. i remember watching an episode of 5th gear where they compared typical mods and noted that the top 2 items that improved the performance of the car was upgraded wheels/tires and driving lessons.
go with wheels/tires. you'll get better performance and probably fall in love with your car all over again everytime you look at it.
