Re: subframe and suspension busings

I'm not sure that there is much difference.... I used polygraphite though.

Re: Subframe and suspension busings

They are the same as far as performance. Polygraphite is just polyurethane impregnated with graphite to help reduce squeaks by being self lubricating. The front suspension parts still need the silicone based goo that come with them. The Energy Suspension polyurethane parts with numbers that end in "G" are graphite impregnated.

Re: Subframe and suspension busings

It depends what you are trying to achieve. For handling solid (aluminum) subframe bushings and frame connectors are the best. Check out http://www.pozziracing.com/first_gen_suspension.htm fop a great discussion on first gen handling.

Re: Subframe and suspension busings

Use the stock ones. The performance gains are minimal and you will not have to worry about lubricating them and squeaking.

I have have had cars with stock, graphite and urethane bushings. No real big difference except noise.

Thumbs up Re: Subframe and suspension busings

Like mentioned above, it all depends on what you want. I have aluminum subframe bushings, poly bushings all around, a lowered stance, and low profile 17" tires. I want my car to feel like a late sporty model. For road confort, I have a US made barge; brand withheld for logic reasons.

LOL, I guess aluminum subframe bushings are too brutal for pro-street guys; that's why only the pro-touring guys are running them.

Seriously, no modern chassis engineer designs in flex. To the contrary, the stiffest possible chassis is the goal. A stiff chassis allows the suspension to perform without rogue inputs. That's why us pro-touring guys are all over solid subframe bushings and subframe connectors.
