I have a spare set of calipers.
They are like new, from a show car.
Fronts are 6 piston, rears are 4.
2 front rotors 375x35mm. No wear, but little rusted, as the whole set is 10-12 year old.
Braided brake lines.
rear are for 22mm disc, so you can use OEM SLK 330x22 rotor!
price is 2100 EUR
PayPal is OK!
Worldwide shipping for extra cost.
