Used them for right under 4k miles on my 07 A4 Quattro 6mt before car got wrecked :(
I got to take some parts off of it to sell or keep for my next one, but that build will go a different route so I don't need these sitting in the shop. 
Has studs but no nuts, you can reuse your original like I did. Will fit all B7 chassis A4 both Quattro and FWD and 2.0T and 3.2 V6 engines. I do not have the electronic mount harness bypass adapters (can order separately via ECS) so you will have to source those if you want to use it in those cars.
