Interesting you should ask...

During a test session at another track, when it was very wet and understeer was an issue, just for the sake of it we tride lowering the front hub using the champ king pin. On that day, what appeared to happen was that more steering was gained, in particular at high speed.

I asked Mick Cragg his views on this set up tweak and he said that in their experience, him and Neil had found that lowering the hub just seemed to reduce stability when exiting and entering the corner.

At Stotfold I had the hub lowered all day and the car seemed fine, then for the final we tried raising it again to the standard position and the front end was even better, I found I could be far more precise everywhere and particularly when cornering off camber the car was able to hold a much tighter line.

I can't put into words the theory of what occurs when the hub is lowered, all I can say is that its effectiveness appears to depend on the amound of more technical and complex corners are present in the track... lots of high speed sweepers in low grip condition, lower is perhaps better. More techical tracks, lots of hair pins, off camber sections or bumpy corners, higher seems better.

I have never had a 4wd car where this mod was present so we are just learning at the moment what occurs, but that is what I have found so far, and will more often just use the hub in the standard position.
