Thanks for all the suggestions. I took the Cobra for its first spirited drive on Sunday up through the hills around Healesville and Toolangi. Lots of winding mountain roads with unposted speed limits, which means up to 100km/h where safety allows.
I've driven this circuit a dozen times in a well sorted 2.0L turbo FWD. I didn't push the Cobra too hard but I'm really surprised at the amount of grip and cornering ability. Power and braking ability was never in doubt. Just need to sort out some rubbing on the front guards when cornering and over over uneven surfaces.
Onto the gears... I reckon I'll leave it alone for now. Plenty of pickup in third from about 60km/h right up to the speed limit. Fourth gear should see me well over 200km/h on the track.
