Anybody used or heard good or bad about PST (Performance Suspension Technology) Polygraphite bushings & Performance front end kits?
I'm about to order their Performance Polygraphite Super Front End kit to re-build my entire front end over the winter & want to make sure they make good stuff before I drop $599. on their kit.Any info/comments/suggestions would be greatly appreciated. Thanks.

Unless you are going to road race the car, I don't see any advantage to the trick bushings on a street car.
The ones that I have installed ride very hard and wore out quickly.

Me too.
Learned the hard way - DON'T use poly strut rod bushings.

Thanks for the input.
I thought I might "road race" at open track events on a very limited basis. More street/mountain road cruising than anything else.Guess I'll stick with what I've got for now
(Rubber vs. polyturethane). I do have 620# 1" lowering coils to put on the front so I figured I'd rebuild the rest of the front while I'm at it over the winter.

I agree poly and polygraphite bushings suck. I'd put in a 1" front sway bar, roller idler bearing, shelby drop and performance alignment, adjustable strut rods, and roller spring perches. Ought to handle like stink then

others where you couldn't tell any difference in ride quality. There's
a wide variance in the durometer (a measure of the hardness) of
polyurethane bushings. Some are nearly as hard as Delrin. Others are
softer than the OE rubber. The polygraphite are among the hardest. The
graphite is added to make the bushings self lubricating but makes them
very hard. A much better solution is to use a pure polyurethane bushing
of appropriate hardness and use Prothane's polyurethane grease. It's a
Teflon based and very sticky, absolutely the best grease I've used on poly
bushings. The suspension design and which bushing locations you use them
on also play a role. Dan Jones

I'd rather spend the money on roller suspension joints. Going to help the car regardless if its drag racing or for handling with the reduced resistance. I've had excellent results with it.

Already have the 1" sway bar (and Shelby quick ratio idler arm & KYB's all around). I had planned on the 1" Shelby drop when I re-build the front end. She handles pretty good now, but there is still some body roll in high speed cornering & I figured It could always be made to handle better (but not at theexpense of street ride quality)...

I am planning on buying 4 1/2 leaf springs with a stock type shackle kit and polyurethane spring eye and shackle bushings. I'm hoping for a tolerable ride on my occasionally driven car. Will this setup drive me crazy? Thanks for any replies.------------------

Nothing wrong with that...
Won't be too stiff at all.

I am looking into milodyne bushings for my wife's 66. I hear they are in between rubber and polyurethane for hardness.Steve ------------------
