Below are the emails sent back and forth with Steve who sells the CHE Products. Steve had the same problems we have with Poly squeaking and binding issues. Until he found CHE. Now to provide us with same peace and quiet without having to go back to stock items. He sells them to people like you and I. Take your time reading each reponse and see how knowledgeable he is in reference to Stang Suspension.
By The Way, Steve is willing to give you a discounted price for all who read this. Feel free to mention my name and this board.
Thanks Henry

Well, like I said just let me know how I can make it up to you. Don't let me
forget, cause that happens easy the older I get.
As for noise, there's no getting around it that the stiffer the bushing, the
more the NVH (noise, vibration, harshness). The squeak should be cured by a
switch to the CHE brand. Some people do notice an increase in the transfer
of road vibration. Myself, I couldn't tell a difference, but some do I
guess. The gain in performance is just huge though. And having an adjustable
pinion angle, like the uppers give, is important.
The stock rubber bushings have enough give in them to require the pinion
angle to be pointed down about 5-6 degrees from the factory, in order to
climb up to 0 degrees at WOT. With more HP, the rear tries to climb even
higher. Putting in Poly bushings cuts that need down to 2-3 degrees, to end
up at zero. So a switch to poly requires a reduction in initial pinion angle
setting of a couple degrees. With solid rod-end type bearings, that goes
down to about 1 - 1.5 degrees (but the harshness is horrible). Like
anything, a change to one thing requires a change to another to compensate.
Rear suspension is so cool... you can make a car go from a spinning pig to a
hooking monster with just a couple parts, if you just understand how the
parts work together. In my opinion, adjustable uppers, fixed lowers, and
adjustable shocks are a huge bang for the buck. For any drag racer, the rear
axle brace ought to be mandatory too. It's quite the piece of engineering
really.
I'll keep your order going then, and like I said let me know what I can do
to make it up to you.
Best regards,
Pontisteve
