Besides gears what would give me the most bang for my buck....

 

I was going to say a tune, but i see you already have that. At this point nitrous would be your best bang for the buck. If you don't want to do that then probably long tube headers and/or cams would be your best bet.

 

H&R Super Sport Springs

 

That's a pretty generic question... define "bang for your buck". What do you want from this buck?

 

Nitrous, and a set of slicks
