I'm running delrin (same as "urethane" sold by TAP, no?) A-arm bushings.
They are hard, I thought they'd shatter if I drove on them. I used to
to switch back to stock, but I'm not so sure now. I think they're
on me. No apparent wear, they seem like they'll last the life of the
as long as I don't crash into a curb or something.
I would imagine Delrin subframe bushes would be way too harsh. Can you

If you want stronger ones, try the ur-q ones. They fit, don't they guys

Heim joints are not suitable for street use, IMO. They wear out and can
break. You gotta have some kind of "give". I had hydraulics (odelay!)
the front of a Toyota truck with heim/himes/whatever joints at the
with coilover springs over a skinny cylinders. The springs were in
on the frame, and cylinders went through the springs and mounts, and at
bottom the himes joints we attached like shocks to the bottom A-arms.
Anyway, they break. Granted, this is alot more stressful than using
on the end of tie rods, or at the attachment points of a sway bar ala
Hale's 4kcstq/2 Bennett Audimotive-style modification, but the point is,
made for racing where you can replace them all the time. You don't want
have to get into the damn inner tie rod thing too often. Not to mention
failure would be pretty dangerous.
I was pretty hard on the himes joints I was using (yes, I could hop the
front wheels off the ground, don't ask me why, Holmes!). ;-)
Just make sure everything is in good new condition. I'm sure that'll be
worlds of improvement if it's currently worn.
