Are there any better OTS solutions for sway bars? Any plans for a SadFAB option? My front RB bar using the ES lube & poly bushings it came with is pretty damn hard to move at all with both ends disconnected.
Does a delrin sandwich madjak posted above improve things over poly noticibly? (I'm not sure if the friction coefficient between a painted bar & delrin bushing is going to be as good as bare steel on delrin - although it's prob better than poly/paint).

I like the delrin sandwich idea. We have tossed around delrin swaybar bushings, and its on a napkin somewhere. But don't expect or plan on anything from us in the near future.

Yeah I shimmed the bolts/bracket with washers to make sure it wasn't too squished which did help, it still takes a disturbing amount of force to make it move.
Something like this looks good if it came in the right size (can only find 1" and 1.25" ID, not 1.125"):

Looks like they have bronze & PFTE type ones: PB4-1250-B - Pillow Block, Self Aligning, SAE 840 Bronze Bearing Spyraflo

Try getting that on a sway bar without going way oversized and using a split bushing. You can find roller bearing pillow blocks for about $30 if you know where to look.
I have a few ideas for sway bushings, we're just too busy with regular bushings and other projects right now.

Im not sure I understand. The reduced friction in the poly bushings are a result of the bronze bearings. So any poly bushing with the bronze bearings will have similar levels of freedom.

That is what I was getting at. The secret sauce is your bronze bearings, the choice of material is how much stiffness you can bear.
What I don't get it why you guys are the only ones doing this. It is a very known issue that poly bushings like to bind and have lots of friction. You and bbundy's similar solutions are what make mt.net such a cool place.
Is the process as simple as measuring bearings to put in any bushing? So you could theoretically make them for any car?

Its actually even more simple than that. ES all pretty much use standard bushing and sleeve sizes. So you just need a catalog of sleeves and bearings that fit their bushings. We are working on a set for a 240sx, but may be expanding in the future.
