I'm running standard rubber lower mounts (thats what was on the car when i got it!) as they are currently working fine and in good condition. The top engine steady has been upgraded to poly and makes a difference with engine rock. Also have an ultimate engine steady on the other side.
To be honest i too have heard bad things (vibration) about poly engine bushes but i've no complaints about my current set up. I've always swapped out the standard engine steady rubbers for poly and never had any issues.
Don't know too much about solid mounts for engines.....would think a little movement is still required or you'll shake you're teeth out and may break something mechanical.

As for the others.....i do have poly teardrop's (again already on the car). As for the other top mounts....my car is a twin bolt typre so don't have bushes. But i had poly top mounts on an old car and i thought worked ok but would change them for solid if i was doing it now

My floors are good so ain't reinforced the bolting area, but i reckon it'd be a good idea...another one to add to my 'to do' list!
Also reinforce the subframes.
I'm pretty sure my suspension bushes are all poly...but they are black so not Powerflex. I've read several pieces of advice that say to use rubber tie bar bushes though....can't remember the reason though.
So you looking at doing any particular event? Altratech 061 is soon is it?

Ah right. Will do that as well then. And will use old school techniques for subframe re inforcement. Will also delve further into the tie bar thing. Regards events, I used to do results on the 061 when highpeak 061 ran the event. but since they murged with stockport, it all went wrong for the results team. And now we dont bother anymore. We do the VK and Drystone results. My dad doesnt compete anymore after they made his v6 sierra obsolete so I'm gonna give it a go in my mini.
Sounds good. I'd like to try the VK sometime but i think budget constraints may put this year on hold. The Altratech is just down the road for me so would be rude not to give that a bash also....need practice first though

Solid mount you subframe, possibly fitting some spreader plates to the heelboard where the lower mountings bolt to.
Standard engine moutings are good.
Poly subframe bushes will give crap handling and fail badly..

If I could reccomend one event that looks amazing it would be the VK. Usually there's a 'special stage' In Steve perez's forest where he tests his stratos and Focus apparently. He's a great guy letting matlock use it! It's a laugh to watch too. A hair pin, bumpy down hill section, and a twisty up hill section for the run down the bumpy straight again. Oh my, it's a brilliant event to watch anyway!I'd like to try the VK sometime but i think budget constraints may put this year on hold.
And cheers Rally 1380 and Minisi35, All noted down. I read on minispeed that the poly inner and standard outer is best, so might try that.
I also have adjustable heavy duty bottom arms. I hink I might polybush this too.
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.

But as for any other bushes, they are all round 'top hat' style with pins through them so can't see these being a problem.
VK here we come then....sounds like fun!!!

The VK has been on our championship for a couple of years, but ive never done it as i believe alot of it is "plot and bash" rather than "pre plot" and my navigator has has bad experiences with that type of event
I did the VK last year as a navigator and it was pre-plot with an hour to plot, although there were a few time controls not listed, you just came upon them!
