Why 21s, most go for 20s on the D3 as larger especially with lowering links will give you a crash harsh ride with unpredictable handling.

The QS is already lowered 25mm compared to standard, and the lower you go the harder the suspension gets regardless of MMI setting. If you go to low then you run the risk of bottoming out the suspension especially in dynamic mode.

Thanks for your reply Mannyo, I was playing about on the "wiiltheyfit.com" website and managed to get the same rolling circumference on some of the inputted tyre sizes I entered, I think the 255/30/21's was one of them so realised that the exact same rolling circumference would not hinder the car at all over the way it is now, but basically wanted to lose the height to get rid of the large gaps between wheel and arch by using one of the suspension methods. Secondly I was looking at the various offsets offered in the 5x112x 21" wheels offered on the likes of eBay and noticed that the offset of my et52 going to an et25 would push the wheel another 22mm closer towards the lip of the arch without using spacers so that it would look flush looking down the length of the car, and giving it a better overall look with the larger wheels.

I wasn't aware that the Quattro Sport was a full inch lower that the non sport versions, I was just looking at the gap I could see and other images of cars I've seen lowered and wanted to get rid of the gap and following others on here who've made their D3's look awesome for the sake of a small amount of drop on their suspension.

I'm also a ware of tyre prices for unfamiliar and less popular profiles, but having a mate who owns a tyre fitting chain down in Cornwall I get a hefty discount on tyres so price wouldn't be something I would really consider when buying 21's for my Audi, it's the look that I'm after most of all... Black Car, Black Tints, 4 Digit Number Plate... I wanted a stand out, wow sort of Car which in the Posh area I live you need to buy some serious cars to fit in and I have the D3 which is an Audi A8 so has pedigree, I just need a touch or two in the right place to make it turn the heads of the others living here who have a couple of £50k cars each.

on the 255/30/21's that you have suggested which is what I was looking at myself, what J width of alloy would I best to look for and also the ET offset to give me the flush look to the arch with out overstretching the tyre. (Overstretching tyres I don't consider safe at high cornering speeds, plus I don't like the look of it when over done)
