Smoking tyres ay troy. That would be awesome for DECA around the skid pan!
For the oil leak have you checked where a set of wires go into the gear box for the reverse lights, i know i've got a bit of a leak there, but with a bit of silicone its all good.
I must say it was a lot of fun sitting on turn one, you could hear everyone screaming down the stright then jump on the breaks. The forester that was running around looked like it was going to go head over heals every time he slowed down! If my car isnt up for a track day at any stage i will be lending a hand again, espically when they give you free beer at the end of it all!
