Did you get them then hkka? Feedback?
I fitted Powerflex on the suspension arm, a good improvement. But the design of the bushes are different with original suspension arm, especially the metal tube for the bushes. Accuracy is important.
Due to the knocking (during braking or de-accelerate) problem, I had replaced by a new suspension arm few months ago. Problem solved. I am not sure what exactly caused the problem. Maybe the metal tube hit the chassis. Therefore, I still have a set of Powerflex wishbone if anyone is interest.
I had problem fitting the anti-roll bar cos the inner diameter for the bushes is slightly smaller than the original, which caused problem. I refund it at the end plus email Powerflex to check.
I got mine from K-tec.
