If you could lower the inner pivott point on the top wishbone on a MGB front suspension what effect would this have on handling?!
Dave Lowe

It would create negative camber. Beyond that it hard to say. The normal way of creating negative camber on a B is to use lower wish bones that are a fraction longer.

If you want to experiment perhaps you should first build a "Stainforth String Computer". See the book "Race and Rally Car Source Book" by Alan Stainforth for details. There are other books on suspension design that might be worth a read before do anything.

Dave,

When you say inner pivot on the top wishbone, do you mean lowering the axis of the shock absorber? If so, I agree that the camber would be reduced but it really would be minimal due to the angles involved.

I've fitted negative camber arms, but it is difficult to say their affect in isolation as I did a lot of other stuff too. Negative camber should improve stability and turn-in; too much can wear out the tyres and cause high-speed wander apparently.

Dave, as stated lowering the pivot point of the upper arm would increase negative camber. Not much staticly, but at an increasing rate as the suspension is compressed. Might be beneficial under high g cornering conditions if your tires are rolling under, allowing you to run a little less air pressure. You might also see some increase in 'bump steer' as the suspension is compressed.

I have had a measure up and it seems that the mgb top/bottom wishbones are parallel to each other,a lot of tuning books I have read say that you get better handling if the top wishbone inner mounting point is lower,this is why I asked!
