ausmini :: View topic - Sub-frame spacers

I like bolts, because if dropping the rear of the subframe to get the rack out you don't bend the studs.
As for why they had 2 systems I don't know.

if I remember correctly, the threads in the subframe are different sizes - dry subframes have 3/8 threads, hydro have 5/16". The studs for dry are stepped to a 5/16" nut at the top

I have studs so imagine it's more work as I will need to lower the subframe quite a bit before being able to access the space to pop the spacers back in.

So is the general consensus do it now and avoid any future issues?

We seem to have made a mistake recently when fitting the front sub frame onto the body, we didn't put the 5mm spacers between the sub frame and the body. It is a 1970 Van and has dry suspension and the sub frame is correct for the car. Before we get too far ahead of ourselves what are the possible issues this can cause??

I reckon a fair bit of damage is possible - imagine hitting a hard bump, the top of the subframe isn't secure & square against the crossmember, so the shock will pass to the rear and front subframe mounts. The front mount is the most likely to cause damage - you might even crease mudguards

Are you talking about the spacer at the top of the tower (#17 below) or at the leading edge of the sub-frame (#6 below)? Attachment: PUB1012 Q02 L.jpg Attachment: PUB1012 Q02-1 R.jpg

It is number 17 on the front sub frame.

Isn't it to stop spigots punching up into body? Can't you just loosen the frame bolt and fit them after removing studs?"

I'm a bit bemused by this as my mini did not have any spacers fitted, anywhere.... OK let me rephrase this. My mini had a wet subframe. I am changing over to dry, does this mean I need to install these spacers if I'm using a dry subframe?

Wet subframe has no spacers, dry one does. Not sure if there is a height difference between the two. Also, wet ones I've seen all have bolts in top, I think many/most dry ones have studs and nuts.

OK Dr mini. If that's the case do you recommend I use studs instead? I can not think of a reason why there is this difference.

Above is true. Studs are easier to align. The captive nuts in a wet subframe can float. I had to use an extended tap once to get the 4th bolt to start.

I wonder if it would be worthwhile trying to unscrew the stud, however remote that chance is..
