Well I don't know what's gonna show as much benefit as gears for the same price.if you read correctly i think he said cheap.:yes
4.10's will set you back 150$
install will be around 200-500 depending on the shop
tuner will be 350$ sooooo if thats the "cheap route" be my guest!
Id say start with light mods that will slowly decrease your 1/4 mile time
