I believe the SLK55's 6 piston fronts are 23lbs I think they're made out of unobtainium and that's why they're so damn expensive.

 

That, and you **** off the Neytiri tribes every time you pluck one from the AMG lounge.

 

I knew there was a cause for all these problems. Leave them alone and don't pick up anymore unobtainium. No wonder we have problems!! Ha, Ha. Roll EYES!!

 

you get a nice discount from the tribe if you have a green 32!! the 6 piston front calipers and the racing brake 340mm rotors weigh 9 lbs per side less than the 2 piston 330mm rotor setup. 18 lbs total lighter and adding 8 more pistons and 10mm rotor size!! the rear setup actually adds 5 lbs per side but your adding 30mm rotor size and 2 more pistons per side

 

Bollocks... If they weren't OEM, you paid as much as anyone else would LOL... Betcha grip-grip could find me a deal

 

now you know what i have in my setup complete with thermal coating. do you think it was a oem price?

 

Knocking on it!!! LMAO...

That's assuming the pucker-moment was a freebie, too... heart-attacks can be 'spensive

Your end result is stunning though, I love 'em. Only thing that would make them better is a gloss finish.
