2.5
I agree with john. save the money on the CF doors and buy yourself some really light wheels. if you havent removed your bumper beams, do that too.
yea bumper beams have been ordered

whats the lightest wheel out there? grams? the guy who has the 11.7 says he could prob go 11.5... this is all in an sti... me havin longer gears think i'll be able to beat it
