hay dude sorry i missed ur post. the te37 sls are 4000 for a set then add tyres, + they r the wrong color, there gunmetal grey, my wheels are lamborghini satin black.
there only 200 or 300 grams lighter so to me that isnt really enuff to go out and buy them in terms or weight issues, my car has hardly any interior, and only 6x9's now + all the carbon stuff its a bit lighter than most r34's.
