I'm going to be fitting some new Protech shocks it seems like a good time to replace the bushes as they are also on their way out.

Has anyone replaced the standard Luego PolyBushes with alternatives i.e. PowerFlex (please give other suggestions)?

What are the advantages/disadvantages for a car that will be doing trackdays?

If I go down the route with another manufacturer what specification do I need to order?

I'm honestly not a fan of polybushes due to their all-too-frequent propensity to create stiction. If it was me, I'd be getting some turned from acetal/delrin.

ETA Tecaform™ HPV 13/ADAF would probably be my preferred choice due to its PTFE content.

Ensinger have trade counters.
