A-arm bushings, Pros - cons?? Options

[East coaster]

What's the best setup for a street car?

Tarret bronze/urethane? (Sounds like a good idea, but never heard from anyone running them)

Needle Bearings? ( I worry about rust and maintenance issues)

Stock with 40K on them? (Has a low "trick" factor, but probably works good)

Delrin/urethane (squeeky........don't want them)

Ditto for rear trailing arm bushings????

Moral of the story: with bearings, all that force from the other 2 axes of rotation are being absorbed by the chassis, which isnt a problem on a track car, but it kills yur butt... especially if you're an old phart like me (3 months and I can legally drink!!!) With that said, I've never been in a car with mueller's bearings. Only in street 996 gt3s (rubber bushed) and then track 996 gt3s (spherical bearings).

theoretically, you are right, but in the real world it will make very little difference

I had the Elephant poly-bronze bushings on my '87 tail dragger, monoballs in the front top strut mounts and monoballs at the inner rear trailing arm mounts

so the only rubber left in the suspension were in the rear shock mounts and those big round things around the wheels (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

the car was NOT uncomfortable at all, even with the heavier springs (22/29mm t-bars, 22mm tarett sways front/rear and bilstein sport shocks) and f/g bucket racing seats

the suspension worked much smoother cause the springs/shocks could do their job as they were supposed to

there wasn't any noticable added road noise transmitted through the metal/metal bushings either
