Ben, the biggest mistake that people make when installing lowered springs is
not also installing shocks that are setup for the springs.  The catalogs I
have for H & R springs or any other type always says, in really small print,
"only recommended if installed with matching shocks".  So when people put
these on that complain that the ride is terrible.  Of course it is because
the shocks are hitting the stops before the can go normal travel for the
springs.  So my recommendation is that you get a set of shocks that is setup
for the springs before you install them or you are going to be disappointed.

Thanks,
