I am rebuilding a clubman and I am looking to fit the new front subframe. I have a selection of different mounts I have collected over the years and I wanted an opinion on the best ones to use. I know people have said what ever type you use you should use all around but I just wanted to know the best ones to use.

I have solid mounts but I am guessing this would transfer the engine vibrations through the shell and would be a rough ride?

Rubber mounts I am guessing like what came off of it originally. Not sure if they are genuine or the cheaper mini spares ones.

I also have a set of Poly mounts orange in colour but these do not look as if they would be very sturdy and they are very flexible.

Lastly I was also after a fitting guide for fitting the front teardrop mounts. I can see how the top bolt fits in to the front panel captive nut but more so the bottom one that screws in from the front, i know that you can fit a towing eye but is there a large washer that would be required to stop bottom of the teardrop moving.

The Mini was designed with a solidly mounted front sub-frame. This is part of the reason the handling and steering are so direct and dynamic.

The rubber mounts were introduced when the target market changed to more middle-aged female drivers in a bid to improve the NHV, even at the cost of the crispness of the steering and handling.

The poly mounts are the worst of all options. Basically they are just junk.

So the choice is yours. You need to decide what is important for your classic car. Steering response and handling, or maybe slightly less NHV, although I have to say that I have not noticed much increase in NHV when switching back to all solid mountings.

All the Australian Built Minis and Mokes right up to end of production 81 had solid front Subframes. Can't say I notice, let alone find them 'objectionable' in any way.

Just a matter of choice - Solid mounts or standard mounts - having used Minis with both variants - I must say there was not really a lot in it
