Regarding the e30/6 vs e92 discussion,I do agree the e36 is a very capable track car. I haven't seen any e30s take the lead though, typically 3-5 secs slower in the NASA, BMW and scda races I've seen. They are both very different from the heavy e92. More tossable and a good amount smaller/more nimble.
However, I have only seen one track prepped e92, the black and red one the polish guy with NASA drives. He is substantially faster than the 30/6's. Otherwise,it seem all other comparisons are against stock e92s. Lucid have you been up against prepped ones?
I think it would be interesting to see what happens when people start spending money on them, I think they still cost too much and so aren't as popular yet. Seems like a difficult comparison to me, but granted I haven't seen all but one built e92.
