Jaydee, why are polybushes crap? My experience, and my dads, are that they are good. They survived holding up a heavy v6 4x4 sierra engine bashing about the preston and many other events, so why not for minis? Surely they can put up with weight and flex? Although floflex bushes suck.


The subframe poly bushes for the mini you can get from so many different manifacturer (all chinese crap anyway) are badly engineered.
Especially those kit with mixed materials or those big floor mountings or teardrops, there horrific.
The subframe will move side to side/back and forth A LOT and you'll loose handling, plus poly once stretched or compressed will stay deformed compromising handling in an unpredictable way.
The original subframe were solid mounted, as for many other modern cars, and were more reliable and give better handling charateristics. Later subframe were a different design and used rubber mountings, at the expense of handling but at least rubber doesnt suffer of deformation as the poly does.
For any motorsport use of a mini, where you need reliability and spot-on suspetion setting, solid mounting the subframe is the one and only way to go.

Hope this helps
