These are real Audi R8 GT wheels in titanium finish fitted with Michelin Pilot Sport A/S 3 Z-rated all-seasons in 255 35 ZR19 (Mk2 TT) fitment. We ran these on our Mk2 TT S line and theein later on our lowered A3 sedan. They rubbed on both cars, largely because of the R8 offset. A lower profile tire would likely have stopped the bit of rubbing we had. These are four each of the R8 front wheel fitment, because R8 wheels are wider and wouldn't work for a square fitment. If you want real R8 wheels, you have to run this setup, poked to fit very nicely but need to deal with rubbing either with lesser tire fitment or modifying the fasteners inside the wheel well.
These wheels are very rare and I only know of one other owner running this setup that I've ever seen. Asking $3,000 or best offer and would like to get them out of the garage as I don't have a car that they will fit anymore.
Center bore is proper for Mk2 TT or A3, which likely means B7 or older longitudinal setups as well but have no idea about if offset is correct. Check the links below for other sizing details.
Here are links to our use of them.
