I have been thinking about getting these for my RX7. It is my summer and autocross car.

I know they are going to increase road noise and vibration; but how bad is it?

Can anyone share their opinions or experiences?

Thanks,
Jason

(BTW: I will be running a solid diff mount as well.)

A buddy just put Delrin in his A arms on his '03 Cobra. Just got it back from the shop yesterday. Expensive solution!! If you have time, stand by and I'll let you know what he says.

Zkeller took them out of his third gen... EL SQUEAKO BANGO BUZZO... he went with poly..

All my other bushings are poly. I am only using Delrin for the subframe mounts.

Carl, are you using delrin for all your bushings?

I have urathane bushings and derllin subframe mounts as well. My car is currently only street driven and I could feel and hear the difference. The hearing part I did not like to much. you will feel almost everything.

Do you regret putting them in?

My set-up is the complete Mazda Comp set-up, plus the Delrin like you.
