That's what I'm thinking too. With a good driver and some nice tires I'm sure the RWD 6MT wouldn't be too far off as long as the power can be put down. I'm sure there's a pretty effective traction control system now that hopefully isn't too intrusive. On some of the 6MT nurburgring test vids I can see the rear end just ever so slightly step out - but it's not out of control or full on drift out of every corner. I think it's going to make for a fun drive if you aren't concerned with every tenth of a second
