For those that are concerned about spacers
<center><img src="http://img.photobucket.com/albums/v373/Salespunk/2055049986_5382d54bed_o.jpg"></center><p>Here is a write up on the DTM safety car:
Capello turned in, backed off, and the car went very sideways. He then booted it and powered through the corner on opposite lock. He was having fun, throwing it about with style on the treacherous surface, and we were both enjoying the performance.
"It doesn't understeer like the road car," I observed.
"Understeer?" replied Capello, in a tone that suggested it was the most disgusting word the English language has ever produced. "No."
Talking to a senior engineer after I got out, I learnt that the DTM safety car is even lower than the roadgoing RS4, with more positive camber at the front and a wider track at the rear. There are probably other differences but those are enough to make it a very different machine to drive, one that an accomplished competition driver such as Capello can exploit.
The one thing I think that they are not talking about is a true LSD. Just thought this was interesting since I bought into the idea of a wider rear track causing understeer.

Seems like the writer probably got that one backwards
Remember all of the negative camber posts awhile back? As ELEVENS mentioned below, I can't recall if it was before or after the oil posts, definitely before the flap posts.

DTM safety car is not fine-tuned with spacers
Enough with the spacers, geez. If a people want to make their RS4 phat with spacers - more power to them - it does help the appearance if you stare at it long eough. The infintesimal change in handling behavior will not be noticed anyway. Handling characteristics exhibited by cars like the DTM safety car are achieved with springs rates and alignment settings (and probably differentials and many other things). Safety cars need to haul... so they are lowered and stiffly sprung. And guess what helps a lowered car look better - a wider stance. Its not the wide stance that makes it handle like that.

I agree that it is not a big deal.
That was the point of the post. Everyone has been concerned about the negative impact on handling which is not going to be noticable to us mere mortals.
