It was reasonably smooth actually. The bits that were on the autocross track were smooth as, the bits that were in the paddock were REALLY loose and there were a few bumps and stuff but all the bumps were just bumps in the soil and not rocks or anything so the car went through alright. In fact I think most of the bumps were just ruts from the previous cars flying through...
That track is SO MUCH FUN though, nothing quite like hanging the tail out at 7000RPM in 2nd gear, snap 3rd and kick it out even more :) And then down to 2nd, minor compression lock, flick into the next turn, SO MUCH FUN ;)
Handbrake still doesn't work though, couldn't even lock it up on the dirt which is just PATHETIC. It works well enough to hold the car on slopes, but doesn't have a chance in hell at locking up the wheels, and I'm almost certain they should be "worn in" by now...
