All these cars are belong to class GT-3, but they are similar with specification? IMO ADAC 14 cars is faster than GTR-3. What do You think?
Although not everybody might agree with me, I tested all of the GT3 cars from all three classes and found them all to be balanced on the same level. They all have special characteristics giving them advantages or disadvantages on certain tracks like e.g. the Camaro is quite fast on the straight but not so good around corners. And I also found all identical cars from the different classes are identical in physics and performance. So all Audi R8 are the same, all BMW Z4 are the same and so on. That's after the latest patch. Before the patch the GTR3 cars were the slowest, the GT Masters 2013 were in the middle and the GT Masters 2014 were the fastest. But before the latest patch they were all on different iterations of physics. Now they are all on the same iteration.
