Audi Q7: need information on changing from 18-inch to 20-inch rim

[docman_md]

I currently have a Q7 with 18-inch wheel (18x8.5, I believe the offset is 58) and would like to know what I need to do to change to 20-inch (OEM, 20x9, I believe the offset is 60). I have heard that I may need to ask the dealer to add a spacer / steering delimiter (which goes inside the steering rack). Any inputs, comments, or past experience would be a great help. Help....

Hmm we just have the 20" wheels but I'm not sure what needs to be done. Sorry.

Nothing, just slap the new wheels on. If they're OEM, they should fit without any spacers. Just make sure you get the appropriate tire size to compensate for the bigger wheel.

You only need spacers if you want the wheels to sit further out to give the vehicle a wider stance. At 9" wide and assuming ET60, you would need to add a really wide spacer to stick the wheel out far enough so as to sit flush with the fender. On the other hand, you'd only need a steering limiter if you added a wide body kit and used really wide spacers (>50mm?)... Obviously turning radius will increase. In short, get the 20" OEM wheels and even with 20mm spacers you won't need anything else except longer wheel bolts.

The steering limiters are a special spacer ring that is installed to the inside of the tie rods on the steering rack to limit the amount of travel allowed by the steering assembly so that the larger wheels (I.E. 19" and above) do not come in to contact with the inner fender while turning. If your stock wheels are 18" then you do not have steering limiters.

You could avoid coming into contact with the inner fender with:

1. A different wheel offset.
2. Spacers.

Personally, I would have the limiters installed.

But by how much would these limiters increase your turning radius? The Q7 is no small car!
