I've used a few poly bushings on other cars. I like them more when I was 25 than I do now at 35, haha. Rubber lasts longer, feels more supple and unless you're on a racetrack provides all the rigidity needed, IMO.
I wouldn't go out of my way to use them on a 100, but if you want to feel a little more of the road seams then go for it.
I'll be honest.. part of the reason for the Poly is because it'll be easier to install, and R&R again later if needed.
Haha, even at 45, I still replace w/ Poly on my other cars for parts like subframe bushings, sway bar links, etc. Stuff that doesnt really articulate much...
My old Denali had lift with everything poly, and squeeked like a carriage... hated it but handling was so improved. I thought I'd stop using poly on trucks...
Slowly, for the 100, Ive tried Superpro bushings on the Panhard, st rack, and Fr Diff carrier. Also my upgraded rear arms have poly bushings on one end and johny joint (which are ball joints in urethane) on the other. All my sway bar brackets have poly as well as the end links. Its very nice how responsive he LX has become.. not over sensitive, but very responsive in feel. No boaty cadillac feel dispite it being a tank. Off road isnt bad either.
Just got back from another trail last night, including washboards, and was still happy w/ how comfortable it was overall. (will see how long the Ironman Nitros last)
Anyway, i just received my SuperPro poly bushings for front arms. If nobody has actually tried them yet... i guess I'll be the guinnea pig.
Not afraid to try new things.. and at worst case, i can always go back to new factory bushings if need be.
Was just hoping someone had actual feedback from trying them firsthand...
