As someone who has an interest in touring car history(especially group a and supertouring) and a gamer who likes to recreate these vehicles in certain games, there is a lot of info out there but I have struggled to find an answer to what type of tyres were used in group A touring car racing? Were slicks a thing? Did different series use different tyres? I have similar questions about brakes. I’m sure there are people on here who know exactly the answer to my question.

I'm a bit late to the show, just watched the movie, which was a frustrating experience. Partially how much of an asshole was everybody.
There were two race incidents that made me wonder, how realistic were they?
Jan's nissan gtr vs that guy's lambo huracan(?), i think they're supposed to be in gt3. First rammed from behind, second one rammed sideways into the guardrails.
First of all, would a gt3 car survive that much contact? From what i can tell, they are not exactly sturdy, usually any contact seem to be race over for the parties involved.
Second, wouldn't the stewards (is that the right term?) get involved? I couldn't find an example of this level of assholery in a quick search, but i do wonder if they would let them keep a place earned by ramming?
