Well I had a good weekend with my C4.1, raced on Friday night and Saturday night, (outdoors, under lights). I made one change to my car that totally transformed it from good to extremely good.
All that i did was increase the caster, and the car was dialed. I also found the sweet spot for gearing my Corally 12x1 which was also performing very well.
So my current base setup is as per my earlier posting, with the additional caster (2 caster spaces to the front, thinnest spacer to the rear).
One funny thing that happend on Saturday night, one of Australia's best drivers (no name to be mentioned, drives a C4.1) wired his motor in backwards for the 3rd final, so in digust he decided to drive the entire final backwards (rear wheel steer!!!), i think he still finished 5th or so! had to be seen!
