Upgrading my 17" too 19" Rotors, on my A4 Avant.

Will it be a straight swap over, or do I need too add spacers or other bits. ? Cheers Guys.

Hi I assume we are talking wheels, please observe the following, the difference in tyre widths and the fact that your car speedo is designed to run with 17 inch wheels so you will have to use really low profile tyres to get the total O/D of the 19inch wheels the same as the 17inch wheel or go to Audi to re program the body control to accommodate the new 19 inch wheels unless you are happy to drive around with a speedo that is not entirely accurate, your choice and I wish you well with it, if the roads are anything like the roads in Essex be prepared for an increase in punctures. The wheels should be a straight swap centre and stud wise, not sure if the offset will be different there is a website telling you which wheels will fit what models of Audi.

i run on 18s as standard on mine , and it would be a good compromise , but i am thinking of going onto 19s when i need to change my tyres.

Thanks bud. What width you running on ? I was looking 285, but don't know if it'll affect the steering turning circle.

235 all round.

I use 19" (255.35.19) on mine. No issues and work well, good ride too but not harsh. 

Reprogramming is not necessary as the wheels are an option. 

Changeing from 17 to 19 will change aspect  ratio so overall circumference change is small and wouldn't worry about it. 

GPS 70mph where speedo shows 71 / 72
