Well I'm really pleased with the extra consistency I'm getting from the car with the graphite arms fitted - I used to lay the car on the track and the balance would be different every meeting, and every race, but now it's much more consistent, the only change I've made in the last couple of weeks has been to go a bit stiffer on the back one night to free the car up. Took the rear toe-in hub carriers off though, they were giving me too much rear grip, which made the car confident, but slower on our tight, slippy track. New 3300 cells are working well too, I actually have some punch for the first time in a few months!
