You guys are right, the bar is a bit too low - for the correct height, check out the pics on
THIS THREAD.
I've adjusted them to the correct height. Still, the Fez handles so much better now. I did a high-speed run (80kph) up the Reefton Spur with the Small Ford Alliance and the car was very well-behaved in the twisties. No skittishness or slithering over mid-corner bumps. There was no discernible understeer or lift-off oversteer, but then again I wasn't pushing it very hard. I may have lifted the inside rear wheel on a couple of corners though!
I could have gone faster, but I was still feeling out the car's limits, plus I'd never driven that road before (and I have a slight fear of heights).
