Spent the morning with the RS3, pulling the wheels off to take a look, and also do some fitment testing. Including the pics here for your reference, and I'll also put a comment in each one so you'll know what you're looking at.

I didn't do any real scientific measurements, but it feels like on the stock wheels there's a just under an inch of clearance to the front strut. It's not a lot, but workable.

I did confirm that the stock wheels that come with the Dynamic package are 8.5x19ET46 F, 8x19ET42 R, 5x112, 57.1 center bore. The front calipers appear to clear the spokes by no more than .5". Concave wheels will be a tough fit over these brakes for sure. "Bathroom scale" weight of the wheels plus tires is right at 50lbs.

I had some 8mm spacers here that I pulled off of my S3 before trading it yesterday, so I put those on with the stock wheels to see how it looked. The stock P Zeros have a HUGE rim protector on them, as you'll see in one of the pics I took of the tire from above. The tire itself is pretty flush at 8mm, but the rim protector definitely pokes. I'll leave it to you to determine if this compromises the look you're going for. It doesn't really look like poke in the traditional sense, since there's no tread there, but it definitely sticks out.

Anyway, if anyone has any questions, or wants pics of anything I didn't post, let me know.

BBS? I thought Ronal made the wheels for Audi!

Thanks for all of the documentation and pictures; very nice. I just love those front brakes / calipers!

 

Regarding the rim protector versus tread width on the PZeros, check this out from Tire Rack...

Excellent! I need to get a set of wheels and Hoosiers for Laguna Seca in about 4 weeks!

This is great info, thanks for posting.

Maybe this is slightly off topic but do you have any insights on fitting 18'' wheels over the those front calipers? All pictures I've seen look like it would be tight.

 

None personally, but a few on our Facebook group have been attempting it with marginal success. I've only seen one wheel that's worked thus far, but the testing is still early. No question, it's extremely tight over those calipers, and you have to sacrifice any hint of concave to even have a chance of working.

I'll see if I can dig up the one wheel reported to work so far.

 

Thanks BlackAce, I'm very interested to hear any options that will work. 18's would open up a lot more tire options considering want a square setup with all seasons for the winter months. And maybe I'll be safe with running something conservative like the Hartmann rotor replicas?

 

Great Info - exactly what I needed. Have you tried fitting the front onto the rear? I was wondering if you can run a square setup (all 4 front wheels/tires). Thanks.

 

I have the staggered titanium Rotor wheels, they were available for Sold orders only in Canada - these Rotors are made by Speedline in Italy! Same offsets as the staggered BBS Blade wheels.

I just successfully fit my winter 18" wheels that I ran on my 2010 S5 - most 18" wheels won't fit, usually because of the radial clearance around the circumference of the caliper, but lots of wheels do not have lateral clearance for the spokes to clear the sides of the calipers. My wheels are BBS CH (model 012), 18"x8.5" ET35, with Michelin X-Ice3 245/40-18 mounted on them (only 1 season old). Clearance to the spokes from the caliper was nearly the same as the Rotors, about 6 - 8 mm, and radial clearance from the outer circumference of the caliper to the inner barrel of the wheel was much tighter, only 2mm or so but it cleared! You'd want to make sure any stick-on wheel weights were on the inner or outer edge of the barrel to avoid caliper interference.

One additional note on the fitment - the centre mounting pad must be thicker than the Audi wheels, as the lug bolts only engaged 3 or 4 threads. I'll get new longer lug bolts if I decide to run these wheels/tires, as I'd want the lugs to be at least 6 or 7 threads deep!
