MAN --- I can't believe that I had been driving this car with the worn out ass end.
Replaced the Koni's and stock springs (totally worn and bottoming out, no damping) with Auto Atlanta Bilsteins and 140# Weltmeister springs.
all I can say is WOW. No more bone jarring RR crossings.
Handles like a dream. Lotsa fun.
Bilsteins set at the 3rd ring from the bottom (4 in total), and very happy with the spring weight versus 95# stock.
