I know  this been covered before but I don't remember the outcome. I  have  
only noticed this on convertibles. I had a 64 Spyder that was a nut  &  
bolt 
restoration. Now I have a 66 Corsa Convertible. Between  34-39 MPH I get a  
solid wobble out of the front end. It feels like a  bent wheel hit 40mph 
and 
its  gone. I pulled all 4 wheels re-balanced  and put the rear on front and 
vice  versa, still there? 18lbs front  28lbs rear. I have running theory 
(guess) 
that  maybe this has to do  with radial tires at low pressure, 18lbs. Whats 
your   experience?



My unscientific experience has been that the radial tires initiate it and  
that if you put different tires on the car the wobble will happen at a 
different  speed.  The dampers in each corner of a LM convertible are there for 
body  dynamic reasons and were added before radials were provided as standard 
 equipment.  It has been a long time since I've driven a LM convertible 
with  bias ply tires, but I don't remember this being an issue then.  I 
wouldn't  worry about it unless it is really bad.  And I'm assuming that worn front 
 end parts aren't contributing to it.
