Looking for some new wheels for my s8, and was thinking about niche targa. I am not sure if they will work. I am not a wheel expert so I thought I ask you guys. Thanks

Net is apparently more or less yes. See visual below.

Essentially inside rim clearance remains same as stock. All the bump out is really on outside--as wider wheel lets tire stretch outward. Since spacer optimum on 20 x 9's at stock ET46 I found was around 12mm front and 20 rear, another cross check should be fine. In plain English tire is sort of resetting itself on a stretched wider rim with tire tread center point about 18mm outward (36mm/2). Sidewall will stretch toward bead area, but that is way away from fender lip in any scenario.

Niche ?? right here, 20's (not sure what model they are). 25mm offset I believe. Took this pix today, just polished them with a Mother's wheel ball and AutoGlym Renovator. Really popping.

I just want to make sure they don't stick out. Thanks

I put 10mm spacers on the rear, in addition to the extra 10 or 15mm reduction in offset (25mm). But I think my wheels are 9"??
They don't stick out plenty of room to go. A wider wheel will have another 1/2 of the width poking out.

The A8 has plenty of space - it can handle ~ 20mm front and 30mm rear. Going from memory - all calcs should be verified.

10.5" is pretty wide with that rim width will stretch the tires too. A 275 is max 11" rim width and will looked stretched. A staggered setup would be ideal imo

No stagger on an Audi save the R8. Performance subtract.

Not only a performance subtract, but it doesn't take much stagger to start actually hurting your diff.

Doc_A8

If you were to stagger, based on the handling and the engine location of the A8, you should put the wider wheels up front- if you were looking for a handling benefit.

That being said. Don't do it.

Stagger wheel width and not tire size in order to optimize wheel placement without having to use spacers. head scratching in 3, 2, 1.....
