Heh

Here is video I took where I pass E21 323 on track. I think it was 323 because of dual exhaust pipes on corners and I could not catch the car on straights. I don't have original high res video here so I cannot check.

E31 were quite notorious for "lively" rear so I would take corners easy too with car like that...
