Suspension - SQ5 versus 3.0T
#11
1mm might be the difference between the overall wheel+tire height. The sidewall height on 21" is 1/2" lower vs 20", which is close to 13mm. So yeah, the 21" wheels are lower profile. Plus your offsets are whack. I believe they are 33 on the SQ5.

True I made a mistake for offsets, but it has nothing to do with the height 1mm
ET33 should instead of ET39 but this is not important in this case
You can put ET-65 or ET80 height remains the same
So normal to have a lower profile and it written on the tire 255/40 vs 255/45, but you are forget that 1" more
This is important
Conclusion: a set of tires 255/40R21 for 1mm lower than sets of tires 255/45R20
Good luck

I do not think this has been confirmed on the U.S. side
Spijun posted about it on the Euro side. On the U.S. side I don't recall any confirming posts, and U.S. EKTA isn't available outside the dealer network for 2014's as far as I know. Being specific, I am referring to either spring rates or damper firmness, which can either relate to or be independent of ride height. (Damper total travel and right height should relate to draw that out--in other words, shorter springs would typically mean shorter struts/shocks.) I do think the ride height issue has now gotten the proverbial fork stuck in it, including other current threads where the answers keep coming back the ride height for U.S. SQ's in the same as the other Q's, including now by a few posts (finally) with tape measures confirming it on the dealer lot. There are some online sites where you can see EKTA parts listings, but it only runs through 2013 AFAIK, and they aren't U.S. centric.
Thus, so far, I'm not sure that sport tuned in the U.S. means any more than optional 21's and some more PSI in the tire settings, or as mentioned previously, frankly that the U.S. marketing/copy writing people are just duplicating Euro PR copy and don't know what the U.S. specs actually ended up being. And we also know from lots of posts there have been more than a few mistakes in the Audi web site and in the PIB, so neither seem definitive source reliable either. I think it really takes part number scrutiny on U.S. specific models.

It seems like the only real meaningful difference between the SQ5 and the 3.0T with S-Line, is the higher-tuned engine. Is that about right? I know the SQ5 has slightly different interior trim, and slightly different rear bits. But by and large, that's it.

True, the same engine only difference in injection and ECU software

That, and a few other items
Front brakes are 380 mm. Seem to be out of the current D4 A8 parts bin from the 3.0T motor version:Quad exhaust a la pretty standard Audi S model (not S line): But no posts on whether this is just trim and sound or there is an actual pipe diameter and real flow change underneath compared to a std. 3.0T.; parts listings of the earlier sections would show this.
- semifloating rotors similar those also found on old C5 RS6, current RS5 and early R8 (those in 365mm and with a much different many piston Brembo caliper). Pin based design with a lighter hat make them somewhat lighter for the given diameter compared to a regular single cast iron rotor, albeit probably still heavier than the 345's on the 3.0T, TDI and Hybrid
- some conflicting info so far, but calipers look like pretty standard issue volume Audi (A6, A8, etc.) with a paint job. Larger mass than the 345mm ones.
