No problem for 2wd spec class, does anyone else even race 235 anymore?
If you are talking about the ENGINE case, that I really don't know how to tell it is a EVO 3 or EVO 4 or EVO 5
But if you look at his pictures above, that purple heat sink with verticle fins, that for sure is EVO3.
EVO2 are much smaller head, and EVO 4 and 5 are pretty much like what we saw on Serpent website now.
Who race 235mm....? Mid-west series (6 or 7 states races hosted by Serpent and others) and Winter National this next weekend...and I think there are more.
However, you won't see 100 ppl racing in that class anymore....if lucky, it shoiuld be like 20-30 ppl tops.
