[DeTomaso] Non pantera suspension question

[Tomas Gunnarsson]

Kurt,
 
What you're describing are the general drawbacks of a live axle
suspension. What lessens the phenomenon you descibe is adding roll
stiffness up front. This comes at the cost of loss of grip up front. I
would start by re-installing your old softer rear springs and see if it
makes a difference.

Subject: [DeTomaso] Non pantera suspension question 

I've been struggling to get my vintage race car to hookup coming out 
corners. It seems to want to lift the inside rear wheel enough that I 
loose traction and just spin the tire instead of accelerating out of the
corner. You can hear it pretty well a little past 50 seconds in this 
video. https://www.youtube.com/watch?v=NQDhmizu3Go I'm not sure if I'm 
driving harder or it's getting worse but I do notice it more and more. 
It does seem to be more pronounced in right hand turns. 

I've lowered the car a couple inches at both ends, have stiffer front 
springs and a 7/8" solid roll bar on the front. I changed the rear leaf 
springs to a slightly newer model that are supposed to be a little
stiffer. 

Not sure what to try next. I have to run the original suspension 
geometry and lever shocks but I could change the oil in the shocks to 
either thicker or thinner viscosity. Stiffer or softer front springs? 
Any other suggestions? 

Kurt
