Hi Paul, one other comment about shimming the crossmember to decrease caster. If I were to guess why 6 degrees caster? The original MGB designers did not know about anti-dive. And even if they did, the British car industry was so distroyed by the labor unions, that they had no money available for fine tuning and improvements. They were struggling to stay alive.

I'm also guessing that Butler knew about anti-dive and designed in into his chassis by tilting the crossmember. This provided for the new anti-dive technology, but increased caster. In a non-adjustable older setup you can have one or the other only. If it works for you, great. I will be doing some track driving so I'm looking for all the technical attributes to help my driving skills. Arthur

Seems like my guessing in the last paragraph above was wrong. The Butler Cobra and the MGB crossmember bolting geometry is the same. Tilting 10 degrees up to the front. Does anyone have any futher comment?
