Rear bush questions

[Tomk]

I have some question relating to the rear bushes on a 2.8 z3.

Mine are obviously knackered! So time to replace as the back end is all over the place and now getting the occasional knocking…

1. has anyone fitted pro - flex bushes? They’re all over eBay and they do full kits plus they are a lot cheaper than power flex. Or are they crap?

2. power flex has many size options for the anti roll bar, is there really that many different roll bars? How do you know which one, vernier?

3. Are there any companies that do a plug and play rear subframe? Ie purchase a re-furb rear sub frame in exchange for your old one? Z-shed maybe?

4. I don’t want the car off the road all year, roughly how long would a full rear bush swop take? Ie roughly how many weekends.

thanks in advance.

Definitely a question for our bush expert @Lee . He frequently changes bushes for peeps on here.

I managed to get a rear subframe and trailing arm at a good price. I rebuilt these as time permitted including new wheel bearings and hand brake parts. After that it was just a matter of dropping the old and putting in the new to me subframe. Items like the handbrake cables and wheel speed sensors will not come out without a fight.

I’m no expert, but from what I’ve seen Pro-flex seem to be a bit mixed, some people are happy, some not so much. The ARB sizes do vary, so measuring yours is probably the safest bet. Refurbed subframes do come up now and then, worth a look. Time-wise I’d guess a couple of weekends if things go smoothly.

Pro flex are ok, depends which hardness you go with. Most common size rear roll bar is 15mm, best double check with a Vernier.

In terms over overhauling it all, we'll be opening up again come spring doing what we call quick n dirty, We drop the subframe and fit new bushes and you drive home the same day. Job takes around 4/5 hours.

@Tomk ^ that is your best option by far. Bring biscuits, drink tea.. drive home happy. No brainer.

Was thinking possibly along those lines

Thanks for the reply Lee.

Personally if you manage to book it in I'd get Lee to do it.. I have no regrets about him sorting mine out....Transformed my 3.0

...And I'm someone used to rolling around it the dirt under axle stands!

Sounds like sound advice, thanks.
