The more I look at my wheels the more I think I need spacers. Anything have them that can tell me which ones I need? No rubbing would be preferential obviously.

FWIW, I happened to come across this D4 thread from a few years back: https://www.audiworld.com/forums/a8-...ce-s8-2883738/ Make sure to realize the spacer related post is actually at the start of the thread. At the end of the thread are a bunch of pictures that are a wide wheel change mod. The wheel final reply in the thread recopies the text of the first post, so it threw me off looking at the pictures for a while. The spacer (first) post also has a lowering link mod, which probably further taxed the real world clearance issues.

I was poking at this for different reasons--possible re use of some nice D3 factory wheels on a D4 and dealing with the bigger center bore the D4's and most other newer Audi's use these days. That uses an adapter that is effectively a spacer in how it affects offsets, though D3 wheels were the older more conservative offsets of the millennium and earlier Audis. D4 isn't as obvious to me on spacer need as D3. Until I just started playing with wheel reuse ideas (winter as well as some weight reduction from the S8 porkers but still in an Audi design), my early reactions were the D4 already looks pretty well buttoned down. But then I am looking at an S8 w/ 275s, 21's, low and aggressive (maybe a little too much in real world) front bumper & integrated spoiler. My D3 W12 was a more obvious candidate, even starting with 275's on 20's that were viewed as very large 10 years ago. Post facelift that I have maybe gave the D4 a little more planted look overall from various angles, but then maybe also to your thinking about spacers.

FWIW, the spacer sizes noted in the linked post seemed a little aggressive to me from what I see on my own new D4. Also note that he had 265's. It was the only D4 spacer post I happened upon, so I don't have (haven't found) other examples from which to derive guidance. Nonetheless, if you have 275's be even more careful from input from that linked post running 265's. Also I was trying to sort that he has 35mm offset per that post. Seems like the D4 factory norm is 37mm, but I do see some Audi wheels at 35mm offsets too; may be A/S7 donors. If post was correct factually on offset and you have 37's, that does relieve a couple mm of clearance issue--he needed even a couple of mm most likely. Anyway my instinct against what was in the post would be to look at 12mm fronts, 15mm rears. Maybe 10 fronts even, but depends some on both the offset at 37 vs. 35 and 275 vs 265. Likewise 12 rear seems a no worries rear bet; I can eyeball on mine the 12's would probably go pretty easily. 12 on mine by eyeball is getting close in front with 275's--hence why it seems like the prior poster was pushing it. At 10mm you have to be careful on the hub center taper for concentric. Technical nuance, but know that down at 10mm if you went there a critical measurement has to be checked on the hub face. I used the 12mm on my D3 (different center bore and thus part # though) and found that measurement worked for 12mm; would have been a yet closer call for the 10mm correctness.

Thx!

Hi what did you end up doing
I have a S8 and even with 275 tires car just looks too "tucked in"

I was thinking 10mm up front and 15mm rear

I just got 275s on my A8 and it looks pretty close, better than the 265s. could it use spacers? sure. does it NEED them, not in my opinion. But this isn't a sports car. I had them on my 750 and had some issues with rubbing honestly.

Just saw this thread (link below) and wow the car looks amazing on spacers

I use D&R 12's in back on factory ET37 wheels w/ 275/40-20. It might just barely work w/ 15's in back, but 12 seemed like the safer way. Have not done fronts so far. My measurements say about 8mm would be ideal max w/ 275's, but can't get hub centric down that low in a 66mm hub center. 10 if hub centric, or back to 12's. I have also never checked beveling in front to be 100% sure the D&R hub centric 10mm spec works. On my "sometime" list is to try fitting the existing 12mm set I already have to front to see how it actually works "in field." My 8mm conclusion was a straight edge eye ball approach. But from D3 experience front is both a fender clearance confirm but also how it looks both in front of wheel and behind, and front fenders tuck more inward in front of the opening than behind than rears do corespondingly. Zero interest in low rent too much spacer kid look.

At least on S8, not clear aesthetically front really "needs" anything. Rear look is incrementally more robust, but could still easily pass as stock. Zero rubbing, and I have since pulled same size summer tires on same factory wheels to re-confirm no issue there after first 6 months or so running.

This is Lou's car on 15mm and 20mm spacers
Pretty good and reminds me of the stance the rs series have

I have 10mm ECS spacers and +10mm bolts on my TDI. 265/40/20 tires on stock rims painted place. It looks great, and 0 issues

I had my car to Mosport, and there were zero rubs at the track. The only time I get a rub is going parking lot speeds and turning to exit while going over the small curb edge bump. If I slow down enough there is no touching, but if it does touch, its light. Once at speed nothing has ever made a rub yet, even pulling full G's at the track.

Keep in mind I'm on 265s not the optional 275. So max spacers for the 275s would be 5mm less than my setup. If I were buying them again, Id do the exact setup again. I hate rubs worse than anyone.
