Wild Bill,

You may be right with the shocks having to little rebound, allowing to much weight transfer to quickly, to the front. I dont know that much about this but maybe the front springs need uprating, to limit dive?

I know they build anti-dive into suspension arms as well, and it all gets very involved, I have experienced some mild shuddering in cars that lock the rear brakes due to unloading the suspension, but it may be worth looking at your bushings etc, as this shouldnt be excessive!
