I would like to see a good reference to OEM parts. I was looking for info on the OEM sway bars that come with my '03 and couldn't find the specs anywhere. Specifically, I came across a chart (
http://www.whiteline.com.au/docs/bulletins/010barup.pdf) which gives a rough idea of how much improvement one may see when upgrading from a specific bar diameter to a higher one but I am missing the original figures. I think this same idea holds true across the board for other parts as well, so we might benefit from a specific thread under the knowledge base forum that can be referenced in an FAQ.
