How come nobody found out about this ages ago that the porsche calipers just fit straight on with no other modification needed? seems abit too good to be true, now off the the scrap yards we all go in search of some porsche calipers lol. exactly what model doe they come off? What type of clearance issue do they have as they look massive? ie what wheels will they fit behind, standard cupra 16" or wheels that suite the likes of wilwood or brembo.
