@Team drivers please have a look at my setup I got to this weekend at practice for the South African national championship to be held in 2weeks time and give your comments. The first thing I had to do is get the car to behave better over the bumps down the straight and into some corners. Then I had to get some more steering on throttle around the sweepers. Changed from the 700cSt diff oil to 1000. It help a lot around the long corners but I need a bid more. Will 2000 do the trick or will that be to big change. Or should I change to 2000 and if I get to much steering rectify that with a bid more droop in front or raising the roll center. Ive added photos of the track. It has however changed a bid since the photos. The straight extension has been completed and it connects up with the bach straight with a slight kink. Your comments will be appriciated. Thanks Wouter

Perhaps fitting a 1.3mm front roll bar to get back some of the steering. Running 2.5 rear and 2.5-2.8 front progressives seems to be a good combination as well. And yes, 2000 in the diff is generally the lowest most people run. Skiddins P.S. I'm not a team driver |

Do you have links to any video of TC's on that track. I've never run that much ride height, do you have any droop at all? |

1mm of uptravel in the front is not much. I would suggest to increase that. 2000 rear diff is a minimum for good on-power steering on asphalt, the car will also accelerate better in a straight line which could be useful over the bumps. |

Thanks Skiddins and Alexander, I'll try your suggestions, but first thing I'll do is the oil and a bid more front droop. What is your normal range for front droop on asphalt? Will a more help with the bumps? The ride height thing, I started around 7 bud the car continues to bottom out so I moved to 8. Help a lot because the car get very unsettled if it bottoms under hard braking. Don't have any videos but will try to get some this weekend at pre-nationals. Thanks again |
