Powerflex complete kits for a 3.0

[Uncle_Clanger]

Can anybody point me in the right direction with ordering a complete new kit of powerflex bushes for a 3.0....they all seem to be different measurements? I'm thinking if I got to replace one then I should just commit to replacement of all the perishable stuff on the underbelly....I know "Grumpy" just did his diff mount....I've got a slight knocking feeling when I'm going through the gears so I'm guessing this one is definitely shot.

Are powerflex generally thought of as the best out there?

I need to stop buying "tarty" bits and spend on some essentials

Yep just done my diff bush and it is a powerflex. From your description I'd say yours has gone. I understand if you change all the bushes to powerflex it does make the ride very hard.

I changed all the bushes front and back for OEM on my 2.8 for that reason except the front rear wishbone bushes which I put in powerflex, mainly as I was told it helped with wandering at motorway speeds and tram-lining neither of which was an issue after but whether that was down to the powerflex bushes or just the fact I changed everything I'm not sure.

Thanks chaps... I've read Mike Fishwick write up on firming everything up and the tramline issue... I must say I noticed the other day on a dual carriageway the uneven road surface was pulling me into the hard shoulder... Mr Fishwick says this is known as a "quirk" or characteristic of the Zed.... I'm not too bothered by it as I'm not a hard driver just thinking ahead for MOT time with perished bushes

Grumpy.... The guys who helped you with the dif mount... You said they were the "Midlands branch" of the Zed Shed? Is that official? I mean I could really do with an exploratory operation on the underside of my car before I spend all my dosh on making it pretty I was thinking of asking the guys in Newbury but im in Northampton so I'm more Midlands really..

I'm still in the dark about the sizes I need for these replacements... The notes on the powerflex site only seems to mention which ones are specific for the M Roadster... No pointer what to order for a 3.0 litre.

Perished bushes have to give "excessive" amounts of movement to fail the M.O.T. and very few do. We, as enthusiasts are a little OTT with things like bushes etc. often changing serviceable components a little early.

If you have a 3.0L Z3, I would suggest putting the powerflex bushings in the sub-frame mounts but leave the diff as OEM rubber. You need a little compliance on the diff mount to save the diff mount and cross member. Putting in a power flex diff and sub-frame bushings makes it all too firm and increases the risk of diff mount and cross member failure, especially if you have a lead foot.
