I recently purchased a set of 2017 Audi V10 Plus wheels from a local owner and mounted them on my 2011 V10 Spyder. I really like the look. I want to thank some of our R8 Talk members for the guidance they supplied. During this process, I read a considerable amount about what was needed to do this swap. Here is what I did:
1. 2017 20" Wheels
2. 66.6 to 57.1 Spigot Rings for the REAR ONLY. I purchased these here: https://www.ecstuning.com/b-apr-part...8aAoexEALw_wcB
3. Purchased TPMS sensors and valves from Amazon. Pre-programmed for the R8. I purchased these: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
5. I purchased Toyo Proxy TR1 Tires from Tire Rack: FRONT: 245/30/ZR20 REAR: 305/25/ZR20 (These are nearly identical in size to the factory 19" tires)
I pre-installed the Spigot Rings and the TPMS Senors before delivering the wheels and tires to my local Audi dealer for install.
The car rides as well, if not better, than it did with the 19" wheels and tires. No rubbing, bottoming out, nothing. Really nice comfortable ride. I really like the look and the TPMS worked right out of the box. I am very pleased with the results and hope this post can assist anyone who is looking to do the same. Once again, I want to say thank you to our members, especially "rottboy", "KfabR8" and "r1".
