Rear subframe options

[reelizmpro]

I was looking to get feedback on the non stock options.

1) polyurethane bushings like IE, powerflex, etc.

2) adjustable subframe via eccentric bolts, etc.

Number 1 I would assume is more streetable since it's closest to stock but does having solid camber/toe adjustments on the rear trailing arms make the overall ride harsh? Pros/cons on a street car?

Camber/toe adjusters don't have any affect on ride quality. The choice in bushings governs that. The weld in kits are much better than eccentric bushings as the eccentric bushings are hard to adjust and tend to drift off their settings.

this may or may not assist you much but i have a stock E30 318i & I went with 80sHA bushes (Strongflex) in the front (CABs, Swaybar) and transmission. After this i obviously noticed more NVH but not unlivable.

Just last week i had the rear done with the remainder of the 80sHa kit, which was the TABs, subframe bushes & diff bush. I also had them weld in the eccentric bolt toe kit and camber kit, set to approximately where the stock settings were.

after this i noticed the rear end feels a bit more solid with less "movement" over bumps and dips. NVH was barely any different. Adjustment from the toe and camber allows it to sit as stock but then i have adjustment when i need it (once i get coilovers).
