Appreciate any help on this topic, I'm doing a TTRS front brakes conversion on my 2009 S3, the TTRS calipers have already been acquired from ebay including carriers and other necessary bits. Now for the discs, I want to see if there are any good two piece lightweight OEM replacement options. What lightweight TTRS discs would you guys recommend and where is the best place to source them? Would prefer something significantly lighter than OEM but at a reasonable cost of course. Another question is on fitment under 18inch Enkei PF01s ET45, would these wheel clear the TTRS front brakes? Also with stainless braided lines, do I need to get S3 or the TTRS version for this application? TIA!
