[DeTomaso] Spring rates

[Charles McCall]

Just for contrast, my GT5-S is a little different. I wouldn't define it as
harsh, but I wouldn't say that my car "frequently bottoms out in
depressions". 

I don't have a lot of damage to the frame rails either. My parking brake is
a different story, as I need to fix it once a year for the safety
inspection, and I inevitably bottom out on something the next day and trash
it for another year...

My stock GT5 is a bit too soft in the rear, it frequently bottoms out in 
depressions, with spectacular results in the mirrors at night. :)

I should probably replace the dampers and springs sometime...

I have contemplated attaching some titanium blocks under the frame rails 
in the rear, for even more spectacular results. :D
