<div class='quotetop'>QUOTE (ae86hachiroku @ Aug 12 2008, 10:23 AM) </div>Thats right - but $4k is a lot to spend to lose 22kg. :blink: You lose more than from removing the sound deadening - and thats free! I can think of 100 things to spend $4k on that will give me a better performance hit then a couple of lighter doors! Unless you've gone all out to get the rest of the car up to speed and spent $$$$$, then cf doors are definitely wank factor!
