Made the last of the major orders this evening to complete this retrofit... B4 Damptronics all around (from Rock Auto, best price by over $300), new front bearing assemblies for my used aluminum knuckles, pads and rotors for the Macan calipers, new strut bearings (Audi TT PN 8S0412249), new hardware for all one time use bits.
My current B8/H&R Sport setup has been on the car for maybe 2,000 miles

. Unfortunately they are TDI specific parts so I'm not expecting them to be easy to sell despite being lightly used.
Also found these torsion beam stone guards while looking at Seat Leon part breakdowns. Don't know if they'll fit but I'll give them a shot at about $50 for the pair, PN 5Q0501560G and 5Q0501560H...
The only thing left is to decide on markings/logos for the calipers. Would like to do something unusual like
TDI but in the GTI font. Or should I just keep it classic with the Brembo logo... thoughts, suggestions?
