I came across these polyurethane bushings from Powerflex, which have a slighty offset stainless-steel sleeve to offer some adjustablity for camber/caster.
Anyone have some experience with these? How would these compare to let's say some Millway Monoballs, considering they are a fraction of the price?


Manufacturer description:
1. For the front lower wishbone: PFF5-5402G Front Lower Control Arm Inner Bush Camber Adjust is essentially the same as PFF5-5402 but with the addition of a stainless-steel adjusting sleeve and spanner. This allows for ±0.5° of camber adjustment to the front wheels, for improved front-end grip.
2. For the front radius arm: PFF5-5401GBLK is made using our Black 95A durometer material and supplied with anodised aluminium outer shells to increase bush stiffness by 300%, controlling longitudinal wheel movement under braking and cornering, and improving longer-term durability. It performs as the non-adjustable bush and allows for +/- 0.75° of caster adjustment, improving turn-in and steering feel, and correcting any steering pull.

I've been wondering about these as well. Seems like a good option for people who just want to be able to correct the side to side differences that come from installing lowering springs in the front but don't necessarily want to run a bunch more negative camber

Not a Corvette.
Having had these and Turner Spherical bushings in my hands at one time, I chose the Turner Spherical bushings.

After more investigations, I came to the conclusion that they are not worth it. What I found out is that Polyurethane bushings generally tend to squeak after some time and need greasing, and even worse they may create suspension binding (search google for more info) when placed on suspension parts with alot of movement (control arms for ex).
Better alternatives that I’ve found:


Caster arm:

  1. Whiteline hardened bushing adjustable 103 euro
  2. Millway monoball 235 eur (sealed) non-adjustable
  3. Turner monoball 300 euro (sealed) non-adjustable
  4. Hardrace monoball (sealed) 312 euro adjustable
Camber arm:

  1. Whiteline hardened bushing 60 euro adjustable
  2. Turner monoball 350 euro (sealed) non-adjustable.
I think I might go with Millway for caster arm and Whiteline for camber arm.
