Whiteline Rear Camber Eccentric Bushings
Is there any value to switching to a poly bushing here? (circled in yellow)

I'm trying to minimize deflection in the rear suspension. I think the part you linked (W63400) are the 4 trailing arm bushings, which I've already done.
The part I linked appears, to me anyway, to be 2 x 2-piece bushings, for the same application as this powerflex part https://powerflexusa.com/bmwe81e82e8...-pfr5-415.aspx. You can see in their diagram that this would go at the inner "spring arm" attachment point circled in red. The diff and subframe bushings are all polyurethane. I've also installed adjustable rear toe, guide and wishbone arms. So at this point that bushing at the camber adjustment eccentric bolt is the only remaining OEM rubber bushing in the rear, and I'm wondering if it's detrimental to leave a singled mismatched bushing pair in there. |

I think it would absolutely be a benefit. I have those exact w/line bushings waiting for install...
Those and the inner trailing arm are the last OEM rubber left for me. |

I use the camber kit as I track and wanted to lock the camber. When you do alignments you set camber first. Toe is easier to adjust and even easier if camber is locked. Unless something is bent...

I know you track your car, you passed me several times at Autobahn on Saturday!
If I may ask, what lockout spacer do you use (3MM, 4MM, etc) and what are your corresponding rear alignment angles? |

Me? Definitely not. I'm slow. They were few 1-ers! Which one is yours? Angle is set at -2.5 but not sure on the MM for spacers. I only remember was different MM side to side.

I was on Hankook RS3 that I bought used recently. They were used on track in 2016. We had 3 sessions so I decided to just wear them out completely. Last year I was on Federal RSRR and this year on Nankang RS-2R, both are few seconds faster than the Hankook RS3's. The white 1-er was moving decently but still on the slow side considering all the work.Only car the impressed my with how fast it goes was the blue Camaro. My friend with the blue 335i ran slicks last year and was scaring me how was can go in turns

I asked VT this Saturday and was told 0mm on left and 1mm on right. My camber goes from -2.5 to -2.2 depending if I run the 10mm rear spring pad or not.

I think the shims are cool and they look like super high quality/solid pieces, but why not just swap out the upper arm to an adjustable unit instead? With the swap you'll also be getting fresh/stiffer bushings and a MUCH more user friendly method of camber adjustment.

I bought them mostly for the solid bearings to replace the OEM rubber bushings. In retrospect this was probably a waste, and I should have just replaced the bushings themselves. |

The issue with the upper arms is getting a wrench up past the hub and the lack of room to tighten and loosen. SPL arms use a pinch bolt design that’s easier but the price reflects a higher quality of material and engineering.

So I've decided to hold off on the camber bushings. A bigger issue are the soft OEM rear top shock mount bushings. They are ridiculously soft and compliant. I'll be replacing them with Powerflex Black bushings this week, hopefully this reduces some of the rear end bounciness.
