Default MMR diff mount install

When installing the new mounts, do they get tapped in from the top of the diff or the bottom? Basically the disk area that stays visible like in the photo... does it go betweent he diff and the floor of the car or the diff and the clamp on the bottom.

Can't quite figure it from this picture.

Top. The little donut bit that's separate goes on the bottom.

Have a set of those mounts, about to install them, have no doughnut bit. Is that supposed to come with the mounts or is it on the car already?

You re-use the one that's on the car.

It's not like the Tein ones that come with a new poly one.

BTW... have fun getting the old bushing out. I like having a 5 ton press at work.

Half and half. There's the little bottom piece that you scrape the rubber off of, and then there's a polyurethane donut that goes in between the bottom of the diff and those lower mounts.

I think Savington is thinking about the energy suspension set that comes with the lower part. IIRC the MMR one only comes with the "top hat" looking thing, and you reuse the stock lower.

949racing bushings come with top and bottom parts, MMR bushings only come with top part and you reuse old bottom mount.

I'm trying to install me MMR diff mounts and have ran into some questions. Is there a metal sleeve that goes between the bolt and bushing itself? When installing mine I noticed a lot of wiggle room and my bushing retainer plate doesn't fit correctly. After reading, I thought I had the bushing assembly understood, but the instal is proving me wrong. Assembly goes: read subframe>MMR Bushing (bigger diameter on top when installed on the car)>read end>retaining plate>nut?

Yes.

That's how I ended up doing mine. You re-use the stock round plate on the bottom.

Was there wiggle room between the bushing and the bolt? There's about an 1/16" clearance between the concentric bolt and ID of bushing.

That stock round plate that you are mentioning is the one with the tab with two bolt holes?

ES kit re-uses the bottom metal plate as well (after you burn all of the old rubber off).

Does anyone sell lower donuts, or do I need to make them? My MMR's make the lower bracket sit to high up, so they can't attach to the tab with the two bolt holes. Needs lowered a 1/4 inch or more.

Thats the same problem I have. Again though, is there supposed to be a metal sleeve that goes between the bushing and the main bolt?

Can someone measure either the top of the MMR bushing, or the ES donut? I'm going to make a few spacers if someone wants to help offset the cost.....

I'll probably be interested. What are you going to machine it out of?
