...but I need to know what parts numbers to get and from where. I know Energy Suspension has the front and rear control arm bushing sets, but I want more. I talking motor, tranny, and diff mounts. Does anybody out there know this info? Thanks.

mazdacomp sells them all, I've heard of fit problems with the engery ones.

www.mazdamotorsports.com the motor, tranny, and diff ones arn't listed you have to call them. I'll be doing them all in a couple months too, also the rear toe bushings.

A friend of mine has the energy suspension bushing and he said it was a waste of time to install them. He is going to change to the Delrin bushings when money permits. The car in question is a dedicated racecar but if they don't work good on a racecar that doesn't mean they won't work good on the street. Check out

www.thepartstrader.com

and look at the project parts trader section. He has a small write up about the problems with dealing with energy suspension.

They'll be going on my '89 T2, which is only driven on the street or the occassional auxoX here and there. I'm going to go with www.mazdamotorsports.com to get ALL my bushings. Some Delrin, but mostly polyurethane. Thanks everybody.

Are the Delrin bushings that much better than the Urethane bushings?

I noticed the large price increase and am replacing all the bushings in my car this winter anyways.

I don't AutoX my car, but I do occasionally road race and mostly just drive from A to B.

I am thinking the Urethane bushings will be sufficient for my needs, but would Delrin be beneficial to me?

Delrin is hard, no compliance at all. I'd stay with Urethane if the car is on the street (although I don't know how harsh this Delrin will be yet, since I'm still putting the rear suspension back together.

don't use delrin on a street car. they don't last too long. you'd probably have to replace them again in a year or 2. they are also nosiy.
