so, ive been searching the forums for about 45 min now and noticed that theres not a comprehensive mod list. I know its all personal, and depends on what you want but I still figured thered be a list of "everything" you could do. (when i say everything i mean everything relatively cheap, meaning aside from putting a V8 dual super // twin turbo etc etc etc.) BTW, i mean modding for performance, not looks

SO! the only ones i could really come up with, at least the ones that ive looked at / i really want...

larger rear tires
secondary spoiler (goes above the rear windshield)
bigger heat exchange
smaller pulley for supercharger
*dual superchargers (for massive more low end torque / more overall power) i hate turbos btw HATE!
dual cold air
bigger exhaust system (downpipe, piping, and remove the muffler or put a smaller one on)
bigger cams but idk how much that would cost at the end (i dont do engine work so id have to pay for install)
sprintbooster
and finally tuned to put it all together

i feel like im missing something though...

anywho, anything else you guys can think of that you could do for a reasonable price for performance?

EDIT: btw all, does anyone know if you can change the speedometer background colors or change the numbers to be lowered? i dont need my speedometer to tell me im going 200+ mph... for one the car cant go that fast but im pretty sure the car would start falling apart at those speeds, so can i change the computer / numbering to show 0-120 for example?
