Thanks for the feedback.
Im still pumped after driving this amazing track. Here is a link with a lap of the track in a Formula holden

I located the oil cooler on the right side of the engine bay, mounting onto the cage but do not have a diff cooler as yet. I will fit one as i was having trouble with 4th gear selection after a 4 laps.
The front end is too low but will be focusing on geometry next week.
