Thanks guys. I think I will be going with the rubber bushings. I have been reading through this site and see a lot of people complaining about the poly bushings. PST and Firm Feel both look like pretty good sites and are getting added to the favorites on my computer. Now time to sleep on it and make a decision in the morning.
I know this is after you were supposed to make your decision, but I can't agree more with going with Moog rubber. Been there, done it (many times) with poly and rubber, and in my opinion, for my cars uses, poly's only acceptable use is for naming a Parrot.
In fairness, poly
CAN produce better handling, but
ONLY if you have replaced your stock seats with race units, replaced your stock wheels with 18"+ units and V+ rated tires. big torsion bars, heavier rear springs (beyond what is commonly available as HD replacements), added or upgraded front and rear sway bars, stiff shocks, etc!
Short of all that you just end up with a hard riding car that squeaks (yes it will, no matter what you are told - no matter how vehemently someone will argue), wears out years quicker than Moog rubber, and is not fun to drive (at least to me).
The unfortunate reality is that most poly advocates have never driven, or rode in a good stock (not worn out by 30+ years) car. These cars are great road cars that handel great and ride smooth with stock stuff, and are far more satisfying to drive. --- But to be fair, I know a few people that
LOVE the sharp, jarring, noisy ride that poly parts and KYB shocks deliver. To each there own.
You can get all the stock Moog parts cheapest from Rock Auto, or for just a few bucks more, your local auto parts store has most everything in stock (if you need it today). --- The only "must have" performance pieces needed (my opinion) is the Moog "problem solver" offset upper control arm bushings to increase caster for better directional stability (still rubber parts).
My personal opinion is that changing to poly parts would be the last change needed if you are building a road race or autocross car. Otherwise it degrades a street car.
My 2 cents anyway, but at least from a "tried it a few times" standpoint.
