Without having to mess around measuring stuff. Is this possible? I have heard of changing to the complete strut / top mount combo but not sure if the 964 RS strut can be used with the 993 RS monoballs?
964 RS strut with 993 RS top mount ?

Actually i think i found the answer but i'm not 100% certain at this point. Several things are worth considering with this.
1 Yes adjustability the plate allows for greater adjustment.
2 slightly easier to swap over to other monoballs(ERP?) if using the "conversion plate" that is part of the design.
3 Probably the biggest reason......Cost ! 964RS part is @ £400 each(and you would always do in pairs) approx 993 RS part @ £270 each approx including the conversion plate.
4. once the conversion plate is in , you just change the monoball which is cheaper still.
The 993RS part would appear to be superior in every way bar one. Because it's two piece, would guess it's not quite as robust as the 64 part.

Speak with Paul McLean ... This is a conversion the 964RS certainly needs to preserve the Badger colonies .....[

Top mounts are interchangeable. The screw in top cap and actual monoball is the same part for both 993 and 964. If it is purely a wear/play problem just replace the monoballs, you don't normally need a complete top mount, unless of course the originals are not there. In summary the main driver to swap is adjustability. Durability isn't an issue for the 2 piece 993 part. Never needed to replace them on the race cars, only the drop in monoballs. You need a big socket, think 40mm ish from memory, to take off top cap ane remove monoball. NOTE. Car must be jacked up before removing top cap, and then re-torqued correctly.
Paul, thanks for the reply. Been a while since i had the Monoballs apart, so i can't remember what comes apart and what doesn't. Are you saying the 964 RS mono's are capable of being rebuilt ,does that mean they can be pressed out and new pressed in? or were you refering to the 993 RS mono's abilty to just change the part that has the monoball inside it?
Kevin, i have a very small amount of play in the ball, which is ok at the moment but will want sorting eventually.

Yes. After removing the large top cap nut, remove the nut holding the strut top in, lower the strut, remove the 4 small nuts holding top mount in to body shell and you have a top mount with monoball ready to swap out. This is the same for both 964 and 993. The monoballs can be bought for about 50ish each from memory. They are just an interference fit large spherical bearing.
Thanks Paul, hadn't realised that. It does make absolute sense.
Would agree a part number would be lovely. Though it would be straightforward enough to measure the bearing after pressing it out . I had a quick look at mine and found the wear was much less than i had thought. So i won't be replacing mine just yet. There was no bearing number stamped onto the top but it's possible there might be one underneath when pressed out. At worst you'd have to measure it or take the removed bearing to a good bearing supplier for identification.
The way the bearing sits is why Porsche tell you not to undo the plug with the wheels on the ground. I guess it would be possible (though unlikely i would have thought) to pop the bearing out of the housing.

Yes, i have a bearing out of the housing for measurements and you are right there are no identifying marks on it. suprisingly it came out with slight force ,so releasing the top nut with the weight on the wheels would be a very bad move.
I can't seem to find an equivalent in a quick surf of the net but i'll keep looking.

Right gents , As usual everything you want to do to these cars has been done in america only ten years ago, the info from their helped me to identify the bearing and they are available from a uk supplier( o.e. manufacturer) priced at £28.10 plus vat each and a bit of delivery!
Group buy for a slightly better deal!
