Replacing Rear Subframe rubber mounts

I bought a set of the ones you have and found I had similar issues. It seems that either the polybush or the crush tube is too big in width. I replaced every other bush on the rear with Superpro and although snug they took nowhere near the effort required to fit as these did.
It would seem that because the crush tube is too big it stretches the polybush slightly when you insert it and you end up with basically an excess of the polybush on one side. In my case I turned the crush tubes down very slightly in the lathe until they took about the same effort as the Superpros to fit. They now fit as I would expect them too...
It's a shame that none of the big manufacturers make a poly for the subframe, I also bought a set from a company called FloFlex but when they arrived I measured them and the tolerances were all over the shop! Promptly binned those and bought these DeFlex ones. Haven't yet put the subframe back on the car and I'm wondering if I should just bite the bullet and put the Subaru GrpN ones in...

Cheers for the input bud
I'm wondering whether I should trim the excess protruding underneath so it's flush with the washer part or if it's meant to protrude , if you look at the original use by Subaru it too has a protruding bit of rubber past the metal sleeve the washer loads onto ??

I then purchased a few from here and there, and they were crap, the Diff support ones were miles too big, ended up trimming it here and there to make those fit.

Well , Avoid Poly torq in Wrexham who make these , acknowledges his bushes are faulty but blames varying car designs on the fault , it's my fault these don't fit apparantly as its an import ?
So another product / seller to avoid
Now the hunt for proper bushes to get my car back on the road !!!!

Taken from fmj's build thread .
They were the only bush I couldn't find from a decent manufacturer. I have seen a thread where some fitted super pro/power flex or similar to a new age (bigger bush) so they do or did exist but the only thing I could ever find was lock bolts and the bush add on spacers. So I got them from a lesser known company on eBay, I think it was flow flex or similar. They may be ok and they seem ok but would rather have stuck to my preferred makes if possible. I will try them and see if I have any issues. Worse outcome will be they perish and I pull them out and have some made for me.
You can get a set of group N original items from ICP for £80. But they may need to be machine pressed in (just a guess as they have a steel outer).

big washer and squash the lot up, theres no point in having the bushes if the are easy to slide in, all the excess needs to be compressed to make it do its thing. i changed my subframe recently to a tubluar one. no mounting bushes but the diffmounts i used powerflex. they was very easy to push in but seemed to wide. bolted up and all squashed nice.

Totally agree but there is a limit to how much excess you can have, these bushes distored so much they looked like amushroom underneath before tightening the bolts etc
Here is a part conversation i had with Michael Mason AKA polytorq in Wrexham after i had explained about 4 times i handt left the sleeves in the subframe hole, it went on far too long..........
Hi,
I managed to remove an Alloy insert
The Inner diamter of the poly bush when installed into the subframe is 24mm
The alloy pin is 24.8mm
The depth of the poly bush itself is 35.2 mm, the alloy pin is 33mm , this results in the extra 2mm of extra polybush that pro…
Mike mason replied
Yes it should be the same. That tells me the hole is too tight and elongated the bush. I will make 4 inserts 24 MM dia. The excess on the poly will have to be trimmed off. So your model is a jap import. Mike

Hi,
Can we confirm im being sent 4 new alloy inserts measuring 24mm and new poly bushes measuring exactly 33mm in depth from tip to end as im in limbo as car is off the road until i fit this part
Thanks
Mike mason replied
Hi. I don't see any point. I need the other parts back for a full refund. As this is a problem I have never encountered before I will wasting my time and yours. Once you have removed the bushes from the subframe take the measurement of the hole dia and the the thickness of the subframe and I might be able to produce a special set for your car. It would also help if you confirm when the car was imported into the uk. I will amend my listing to advise owners of imported cars to provide dimensions before I ship. Mike

Check out my other stuff. I make high performance engine mountings. Whichever brand you have bought the material is not as tough as Polytorq. You mentioned if you get a cut in polyurethane it will split. True. But not our material. It is TDI. where's as all others are inferior MDI. our material will never split. Ever. Good luck

You make engine mountings ? **** good luck to those guys trying to get the engine to fit afterwards .

With all this experience shame you couldn t develop a Subaru subframe bush that fits

Well Porsche are doing ok with my engine mounts. You missed the chance of rebushing your car for next to nothing. I will go on the forum and select someone for a full set for free now. Watch this space. Like I say. You don't know who you are talking to. That's why you run around in a Scoobie and I drive a Bentley

I emailed SuperPro asking if there was a specific reason why they made a bush for every other part of the suspension but the subframe. Just got this reply back...
Hopefully they will have something available in the not too distant future? For the moment I've fitted the FloFlex bushes having modified them all to be the same size but I'm not convinced they will last that long...
Good Morning Paul
Thank you for your enquiry, I have asked the Rand D team about these bushes. Simply when we had a car in for R and D they were not deemed a bushing that would be in high demand due to the nature of labour costings to replace them. We are now going to look into these and to get them introduced to our range.
I will not be able to give you a time scale on how long this will be, due to the nature of gathering dimensions getting parts made for test and then testing them. This is a rigorous process that is adhered to all bushings produced by SuperPro so we can eliminate any failure / manufacturing issues before they are sold and fitted to vehicles on the road.
I hope this will not deter you from choosing SuperPro for your Suspension Part requirements.
Please feel free to call or email me to discuss further if necessary.
