Or maybe the renewed interest is the thread and the raw speed of the beast. I don't mind a little tech in my pan car. Here is another sketch. All that is done here is the spring is moved off the kingpin to allow more travel. The lower arm is made movable so the roll center can be adjusted. There are simple cars like the Corraly C10 x and Speed Merchant speed spec already available. It would be nice to have a car that would capably handle the very high speed on the straight.
