top mounts, top mounts, top mounts

[Alburglar]

Aoplogies if this is a boring subject for you lot, but searching the forum has not provided a definitive for me.
I have B4 v6 Quattro Avant with factory sport suspension (same as S2 but four stud and 2pot calipers). I have S2 H&R lowering Springs and before that the original s2 springs. I am tired of the damn top mounts malarkey. I can't find the sachs 802 453 top mounts that would work with the mount savers. ...and to be honest I still don't get how that works, but happy its a well trodden path, but can't find the mounts...

Has anyone found a solution to get the standard Febi's to last more than 5 minutes?
Or an alternative that works outside of solid top mounts?
There must be a polybush equivalent that works somewhere? even of a different vehicle that needs turning down a bit or I don't know.
Anyone, been there, done that, got the t-shirt and can save me 100hours messing around?

There is no cure for this, it has been a problem for decades. If you consider the basic design, with an M12 hole, is same part as used in a Polo from around 1992 (and backwards compatible to the beginning in 1974), its use in the 80/90 up to the type 8C of 1996, any trainee engineer could see it wouldn’t be reliable. The best solution I have found is the TRW JSL104 which seems to be the most reliable of the multitude available, including the original 8A0 412 323 D from Tradition.

Perfect, thanks I'll give that a go.

Ordered the TRW,.but anyone tried 1J0412331C or the polyurethane equivalent?
...I've seen people recommend the washer caps, for these mounts, as a replacement to the OEM 80 ones, but the O/D is, apparently 10mm wider so unless you turn them down the plastic cover doesn't fit anymore (which seems largely aesthetic only?)

MK3 golf etc powerflex PFF85-239 looks damn close too

I set of Powerflex PFF85-431 were £33 on ebay, but listed strangely, so I've ordered them to play with. Should be equivalent to 1J0412331C:

"

• 10mm Ride Height Drop: The primary feature of this part is that it allows the front strut to sit higher into the body of the top mount, lowering the vehicle's front ride height by 10mm. It is popular for drivers who want a slight extra drop with lower springs or coilovers.
• No OEM Modification Needed: It includes special black polyurethane top cap spacers (95A durometer)"

...might need to hybrid with Audi 80 bits like the washer cap, to get it to work? And sort where the bearing sits? wish me luck...

Looks like this with slightly different bearing design
