I rebuilt the rear leaf springs on my '67 MGB GT a couple of years ago, and in
the process, modified the rear geometry, a la Fred Puhn (How to Make Your Car
Handle). They are de-arched, with extended rear hangers, and Koni tube dampers.
This left the rear sitting a bit over 1 inch high. I just recently bought and
installed a set of 1.25 inch lowering blocks which levelled the rear of the car
perfectly, but introduced a very unsettling movement of the rear end. When I
suddenly let off, or jump back on, the throttle the rear end twitches (to one
side off, other side on). Nothing appears to be loose or incorrectly installed.
Could this be due to the change in pinon angle caused by the lowering blocks,
and will shimming one end of the blocks to restore the original angle eliminate
the twitch? Any other suggestions for a cure?
