MG MGB Technical - New shockers, more scuttle shake?

This spring I put new blue polyurethane bushes, new springs and new standard shock absorbers on my ī63 roadster, and pumped the right quantity of EP90 oil into the steering rack. In most ways, this is a huge improvement, But there are some unwanted side effects: There seems to be quite a bit more scuttle shake now, and also more feedback to the steering wheel.

Maybe this should be expected, but it would be interesting to know if anyone else has experienced the same thing.

Tore,

I wonder if you are seeing the effects of an out-of-balance wheel/tire that was previously being damped by the soft bushings. Check the balance of your fronts, maybe switch them to the rear and see what effect that has.

My car does crash into potholes with it's GT front springs 10% uprated lever arms and 3/4" ARB. When it does the steering kicks as well. There is no visible scuttle shake wich implies an over flexible body. The Strong "one piece" feel of the MGB monocoque is one of the nice things about the car. I just accept it as a trade off for the sharper handling.

Maybe I am too sensitive :-)

What I describe as scuttle shake is nothing violent, it is more like a vibration occasionally felt on bad roads, noticeable if you look at the windscreen frame.

When I jack up one corner of the car the doors are closing very nicely, so the body canīt be THAT flexible!

I suppose the kickback in the steering is also made more noticeable with a light Moto-Lita wheel than with the original heavier wheel.

Harder dampers, stiffer springs or suspension rubbers *will* give a harsher ride over certain surfaces. That is the quid pro quo for sharper response.
