I've looked at a ton of threads about spacers for my white S5 with the titanium package. The consensus is that 20/25mm front/rear is the right amount for a car that is dropped 1"+. People generally don't agree on what spacers to use with the stock suspension. From looking at pics, I feel that with the stock suspension, 20mm in the front is slightly too much and 25mm in the rear looks good.

Is it ok to run 15/25mm front/rear spacers? Does the 10mm difference have any ramifications? Does it affect handling, tire wear, or anything else?

For others finding this thread, here are some good pics:
15/20mm stock suspension (jotsy)
20/25mm stock suspension (Ben)
20/25mm stock suspension (AMDG)
20/25mm stock suspension (AMDG, angle and side shots)

One additional piece of information to save others from hunting it down: HR "DRA" spacers bolt to the hub, then the wheel bolts to the spacers. The HR "DR" spacers require you to purchase longer bolts. DRA spacers only come in 20mm+ sizes.

Found this car running 15/25, though not on stock suspension, so I would guess there isn't an issue with the 10mm difference...

The 20/25 setup works fine and looks good even on a lowered car. I have a StaSis suspension setup lowered about an inch with the stock 2008 S5 wheels. No rubbing even when used on the track. Don't go any bigger. If I had to do it again I think I would go 15 front and 20 rear, but it's so close

Right, 20/25mm is the biggest you want to go and most people say looks good with a drop. Without a drop, the 20mm in the front is definitely slightly too much and the 25mm in the rear is subjective: either just right or slightly too much.

Interesting to hear someone with 20/25 and a drop say they would go with 15/20 doing it again.

I think, from looking at pics, that I like the aggressiveness of 25mm in the rear. This is why I'm contemplating 15/25 with stock suspension. I know I'm totally over analyzing this, but it's what I do.

I was very happy with 20/25 (F/R) prior to lowering the car. I tried 25/30 and it was too much. With 20/25 and lowered, the car looks perfect IMHO!
