Hi guys I've tried doing some research but struggling to find a definate answer. Looking at upgrading the brakes on the s3. Found a set of Porsche 18Z calipers for sale. But buyer is also unsure whether they will fit the 8l? Also a set of brembos that have been on a polo gti (unsure what there from originally) but whethere they would fit? All help is much appreciated. Thank you
