Polybushed rear beam mounts

[Niall]

And the inserts are designed to remove passive rear steer completely where as if they redesigned the standard rear mounts, you would still have passive rear steer albeit reduced.

I agree but surley pug spent ages designing the rear mounts to give the passive rear steer and the correct ammount with lots of testing involved , so if powerflex stiffen them and testing is something they seem to do very little of who knows what they will be like.

You could say exactly the same about any aftermarket product. Do you think companies like Bilstein pump as much money into their R&D for a shock for a 306 as Peugeot would? No because they don't have that kind of money especially to do it for every model they make shocks for. They would never make a profit!
