All of this is on a 51 cranbrook, factory stock everything. I did a spring change because during the brake job I noticed the right one had the bottom coil broken off and wedged in there, I dont know when it happened but it was obvious I needed a set of springs and the search was on.
I installed a set of the Moog cc850 coil springs. They were 2.5" shorter than the factory springs but they had the car nose up to stock height anyways. Definitely firmer than the stock soft floaters.
My basic review is that it needed to come down a wee bit more but it was fine as is but I have a 3" drop in the rear so it was kinda nose up stance with the new springs up front.
I put it on the road and holy smokes the car has never driven so nice! It was super stable, floated like a caddy smooth ride but not wafting around and floating around like it used to. These $50 springs was the best thing I have done for my car so far! I love them, Love them so much I figured, what the hell, for $50, lets cut a coil and see how she sits. PERFECT! the ride is amazingly flat nosed around corners, handles smooth as glass, height wise it sits where the fender lip is at the top of my tire(15/215/70) and couldn't be happier with how it looks and rides and handles.
This modification gets my 2 thumbs up for its simple install and huge change in the cars attitude, I tamed the floating beast and she liked it!
