[DeTomaso] Resetting Ride Height With Stiffer Coils

[Pantdino]

I can't see Ken's drawing, but I assume he made use of the 350/450 ratio.

Perfect, thanks Ken.  So I need to come .45" down the perch.  I'll start
ith that, and go from there.

Mike,,

   I think the stiffer springs will compress less under the weight of the
ar, so you need to move the perches lower.  See drawing.

K, time for the math wizards to have a head shed . . .
I'm swapping out my front springs from 350 lbs to 450 lbs, and want to
chieve the same ride height.  Since I won't (I assume) get as much spring
ompression with the 450's, I'll need to revise the spring perches on my
ldan shocks.  I'm guessing I'll need to compress them slightly more on the
hock (the collar height up the shock body) since the springs won't drop as
uch when I let the car back down and the springs settle in.  My car is
tock up front with the addition of an aluminum radiator, so probably close
o stock weight on the front wheels.
Any thought on how much more to compress, or notes form someone whose been
here, would be helpful.  Pulling and readjusting or trying to adjust the
ront on the car are both a much bigger PITA than the rears.  I'd like to
ave to do it as few times as possible.
Thanks in advance for your sage advice.
