correct, the requirement for the stiffest bushing may not be necessary on a 250 but the 350 dependin on how you drive it certainly can benefit from the 90 duro bushing.

So I just ordered these bushings and am pretty eager to get them installed along with my new tires. What will be the best toe specs now for prolonged tire life?

Well the accepted spec for toe-in for prolonged tire life is zero degrees or very slight toe-in. Obviously with this information on the flexibility of the LCA bushing, the front tires will toe-out on braking regardless of your static toe spec.

With this bushing, toe out under braking is minimized so I am speculating that even with maximum toe out (within specs), the inner tie wear issue should be minimized.

Mike or Lobuxracer, what do you think?

Agreed. I'm only waiting for the NVH report on the solid bushing before deciding which I will install.

Sounds like a great solution. Seems like ride quality is unaffected that people could install in their 250/350 if they are experiencing issues.

I recall this being an issue was back in 2006 when I bought my 350, so, it's not so much if they're experiencing issues. It's something I would recommend to almost anyone with any 2IS.

For those that ordered I should have the correct, centered bushings shipping today. They sent the eccentric version previously and I have not characterized the impact on roll center and dynamic toe and caster so I did not want anyone testing that as well. Orders should ship next week. Hopefully get the sphericals on this week.

Just curious what difference about the eccentric and spherical version? I'm not quite familiar with bushings.

Also, is there an increase or decrease in road noise switching to these bushings which one maybe concerned about for general street use?

Eccentric=offset mounting point which will change the alignment setting.

Spherical=Solid steel ball and socket with a Teflon lining. This has the least deflection but possibly the most NVH

NVH=Noise, Vibration and Harshness. This is the concern that everyone is trying to determin the levels of with the different bushing options.


Hope that clears things up for you.

is the "poke" issue addressed in this design?

It is mitigated but not resolved completely. Until the bushing is silid there will always be a little deflection. The OEM bushing allows more poke because it has very little constraint and the vector of the movement is both poke and push.
I am swapping in an LSD right now so hopefully get humpty back together and do some testing with the spherical bearings.
