1995 DTM regulations?

Don’t know which part of the forum I should post this, so sorry in advance if I am messing things up.

So I have googled the 1995 season of DTM a bit, but can’t find out much about the cars. Anyone know a bit about the topic or have found some webpages about detailed information, rules, regulations? As far as I know some (or all?) where 4x4, and they used V6 engines. But what were they limited to? Could they use carbon fiber panels or chassis? Really want to know more about this era of the DTM racing series, thanks for help!

And did they use V6 turbos or NA?
