S4 Avus wheels vs S6 wheels on a coupe (loong)
Just thought I would share this with you in case others were thinking of running either of these wheels.
For a while I have been looking for some S6 Avus 17X8 ET35 wheels for my coupe. Basically, I wanted these vs the S4 Avus 17X7.5 ET45 wheels, so I would have a wider wheel and not have to run spacers.
I already have a set of Avantgarde 17X8 ET35s, so I knew the S6 wheels would fit.
I finally found a nice set and locally. The wheels came with 255/40X17 tires aready mounted. About 1/3 tread left on them. I had some real concerns about whether or not these would fit on a coupe. Would they clear the front tie rod arms. Both my Avantgardes and S4 wheels had 225/45X17 tires on them.
Now I am running Ground Control Coilovers, so the front spring perch would not be a problem.
I mounted up the wheels and tires. The 255 tire comes real close to the tie rod end. The arm itself sits slighly higher than the tire. So arm was not a problem, but I couldn't see any daylight between the tie rod end and the tire.
I spun the wheel a few times, pulled the wheel and checked for rubbing on the tire. NONE.
I went for a drive on the streets near my house. Pulled the front wheels and checked the tires for rubbing. NONE.
I went for a sprited freeway drive, pushing it on the on ramps and favorite S-curve off ramp. Pull the wheels and checked for rubbing. NONE
No rubbing on the fender, inner or outer. I do not run an aggressive lowered stance, so this could be a factor if you are. I like a little give.
It was 90 degrees during the road test, so expansion would have taken place.
Now some comparisons.
The S4 wheel with 225/45X17 Michlein Sports weighed 48.5 pounds.
The S6 wheel with 255/40X17 Continental Sport Contacts weighed 47.5 pounds.
Wider wheel with wider tire and it weighs less. Well that was an unexpected plus.
The steering feel is better. Not as light as with the 225s. That is a plus as I always felt the steering lacked a enough road feel.
Continental tires are not impressive. Squealed, but held pretty decent.
This tire may be narrower than some other brands of tires, so I may have a rubbing problem with another brand. I will probably run some Pirelli Zeros. I ran these on the track for a couple of days, as they came with my Avantgarde wheels, and figure I would use them up. The held pretty good, and wore surprisingly well.
Going from a 205/60X15 stock to a 255/40X17 tire, things just keep getting better.

Looks good...
I am running Yokohama AO32R 255x40x17 with SSR comps 17X8.5 ET 35. I had to add 5mm spacers but have about 1/8 clearance and have had no problems with rubbing. If you can't see any light between your tie rod and the tire it might be good to add a spacer just to be safe. I added 5mm spacer to the rear as well just to bring the tire out to the edge of the fendor like the front. My wheels with these tires weigh 42lbs each.

The 8.5 may make the difference
I don't know how much of that extra 1/2 inch on your wheel makes, or whether it is in or out, but I will check when I get the other tires. I may be able to get away with only 3mm.

I notice some notes with those rotors I just bought...
in your picture poster. Is there anything I am going to have to do if I am running the same calipers? Please advise.

no, sorry.
I like the Advantgardes a lot. I use them for the track, as they weigh a little less. Now I know that I can run a wider tire on them. Actually, I have one set of Avantgardes and 3 spares.
