damn, im in the same boat, i wanted a stage 2 but they gave me a stage FOUR for the same price... i didnt know better so i was like.. sure! .. do you have any idea how long a stage 4 would last if i drove it nicely? at least 20,000km i hope!
my stage 3 really isnt that bad, i kinda like it...its not bad like a mustang...someone told me it actually feels like a stage 2 almost.. if any one has ever driven a g35, it kinda feels like that
