I been talking to www.whiteline.com.au again for a 22mm rear swaybar. Today they confirmed via e-mail that they can supply me with 22mm bushings for the adjustable bar and is AUS$285 or US$225.

I'm going to order it withing the next two weeks. I have no doubt that the rear of the car will be significantly stiffer. I'm thinking of setting the bar to the softest setting when I first get it and go from there.

At the moment I can only get poweroversteer if I mash the throttle through corners, and even then there not much of it. otherwise the car handles well, it's predicatable. I didn't know it was so easy to chew through tires on the track.
