I still got my H&R rear wheel spacers. Want to sell them.
There are widening the track by 25mm each side (rear wheels only), are made of some special alloy (really light) and even come with TÜV approval for Fbodies (4th gen).
You can find the TÜV approval (Teilegutachten) in
http://www.hr-spezialfedern.de.
In the bottom left corner is a link to "TÜV-Gutachten"
I do not know what the dealer paid for them when I purchased the car, but yesterday a vendor told me that the price for a new set will be 150EUR.
I would sell them for 80EUR incl. shipping within Germany.
When the car is lowered you need to widen the wheel arches.
This is a cheap legal way to widen the track, if the TÜV nerds do not approve wider wheels.
Just for the looks.
If somebody is interested, drop me a PM!
