the flexi pipes unclip where they mount to the rear beam and you can pull the solid pipes through to gain more clearance So you can get to the bush.
 
Ah ok, I think I understand what you mean. I was thinking about the solid pipes on the rear beam, but because they're all bent to shape before they're clipped in they don't budge. I didn't really consider whether the front pipes could move.

I think it'll still be a toss up whether I go for that and deal with the inconvenience, or whether I drop the beam to make the job easier and deal with the brake bleeding afterwards. I just really don't like messing with brakes!
 
How much flexibility do you have in the recently installed poly bushes? Do they still allow the beam to perform the passive rear wheel steering like the originals?
 
We can supply you some poly bushes, if you would like a quote then PM me please.

I believe the passive steering is due to the angle of the mount for the rear beam, that's not changing so the behaviour should still be the same. I've not put the rears on yet so I don't know for sure, but when I put the fronts on it gave me the impression of what a brand new car would feel like, everything really tight and secure. I would expect the new rears to do a similar job.

There is some but not as much as the orignal bushes. They are much better for lift off oversteer :D
