There's some other tid-bits in the other FAQs as well. I'm re-doing all the bushings with a set of the M5500 UCAs and was just gathering info on the bushings and setup.
That's something that surprises me on this forum - the part on MM's page for the pan hard bar tech where they talk about how important it is to keep the rubber bushes in the upper control arms. I've seen so many folks here that are using some aftermarket uppers with poly bushes and wondered if they would run into issues. Maybe it doesn't matter than much if one isn't also using a pan hard bar? Or since they don't tend to track their cars, maybe they aren't seeing the stresses and forces that would push them into part-breaking territory?
