transbrake with caltracs, help

hi I assume you have a throttle stop? does it come on shortly after launch?
If it does, then you're unloading the chassis, makes it hop up and down.
what are the rear shocks set on? do you have any preload on bars or no preload? which hole is bar set in? the lower hole would prob be better for trans brake. trans brake is like a stick car. no preload on suspension. it shocks it hard. I have my rear ranchos on # 7 setting. what tire pressure you run? how wide is the wheel? prob should use a wheel as wide as the tire if not litle more wider. on a stick car usually run a wider rim compared to the tread width. it's like anything else, takes work to figure out what the car requires or likes.just foor forthought
