Re: What causes heavy steering at racing speeds

Frank,
ratios are very critical and can drive one nuts, the Trevor version has an eccentric for the pivot of the rocker and the push rod anchor on the chassis. Personally have never explored its use on a 40, will be interested to see how goes on Iain's car. Have found it usefull on high downforce cars and also on softly sprung rear suspension.

off set is 1/8 mm inboard of the rim centre so scrub =4 1/2 =114mm. Thats reasonable enough in the circumstance, would be nice if it was less.
What size tyre are you running on the 9" rim

Jac Mac,
I would be suprised if Ross's car is rolling on positive camber, he posted some photos of the front tyre some time ago, it did not look that bad but temps will tell the story (hint,hint RossN)

BTW success is 99% failure

Russ N,
You get longer wheel travel for the same length shock and lower shock velocity + rising rate. This all depends on the geometry of course.

Not all keyboards will support the whole of the table if your running WINDOZE, but DOS and LINUX generally ok
