Looking to fit 18" alloys to A6 c6 avant

[Dave8819]

Hey guys I'm looking to see if there is anyone out there who can point me in the right direction. I have recently bought a a6 le mans avant but it didn't come with the le mans alloys so. So after a bit of digging I found out my wheels are 19" double five spokes od an A7 s line. I'm looking to possibly replace/refurb them but unsure atm buy I will need a second set of rims either way so I'm looking to either track down a set of genuine 19" le mans wheels with in Northern Ireland if I can, but I'm considering fitting a set of 18s just due to cheaper tyres and chappy roads where I live. I have saw a set of 18" double 5 spoke (similar to the a7 ones i have) A6 s line rims from a c7 and a set of 18" 5 spoke A4 sline rims. Both sets are cheap with tyres but I'm not 100% sure on the fitment being ideal plus unsure how the car will look.

Any help and advice much appreciated guys

18" will fit don't forget you'd have to get the tracking done. I believe the standard wheel size for a le man's is 18"
