front supension beam bearings
Re: front supension beam bearings
The off road delron bushings will be really tight and have to be fitted. Once fitted they work quite well but can be a challenge and tighten up under cornering.

If you use the Delrin front bushings would it be better to cut off the ears and slide them in to where the bakelite bushings would normally be. Ream them out to 1.50ish... and use the standard Vee aluminum spacer (or the trick SR spacer) on the sway bar and the standard dust seal on the spring pack?

The latest trick is to run needle bearings in the inner and outer positions. Reduces sticktion.

1) Exactly where in the rules does it say that the inner beam bearings are free? You might be able to say Delrin is a close substitute, but a needle bearing?
2) Where do you find control arms with pristine inner races. Seems you would be better off "wearing" the inner race into a round condition and sizing some Delrin inner bushing for a proper fit.

C.3.A2. The use of any anti sway bar(s), mounting hardware, and trailing arm locating spacers.hardingfv32-1 wrote:1) Exactly where in the rules does it say that the inner beam bearings are free? You might be able to say Delrin is a close substitute, but a needle bearing?
Probably in the same place that roller link pin bearings are allowed. You could argue that the inner bushing is also a spacer.

Re: front supension beam bearings
That is a possible way to argue the issue, although this sentence is discussing the use of a sway bar. It could be said that it would not hold true for the control arms with the main spring(s).
This still does not solve the issue of improper clearance between an always worn control arm and a precise needle bearing.
