I've just replaced my front ARB bushes with Powerflex ones and the double ball joint drop links all from Racetech here: http://www.racetechdirect.co.uk/car-parts/suspensi...

Took the Cerb for a run and I had to stop to check I'd done the wheel nuts up, it sounds like I'm driving a cement mixer with vibration at low speed & low RPM. I will pull the wheels off and check I've not done something stupid but it seems to be horrendous vibration from steering input and braking. Anyone else had this? I know Powerflex bushes transfer more vibration but I can't believe it could be this bad from only the ARB plus the drop links.
Gutted if I have to go back to the standard bushes and drop links, I've just wasted money!

I have the same setup with no ill effects at all

The front ARB is the only place on the car that I have Powerflex bushes

I do have fairly new rubber bushes on the drag struts, and worn bushes will cause those symptoms

I reckon there must be some sort of fitting issue, unless there is something else that changed at the same time

Thanks, only the ARB drop links were changed as well but I could well have worn bushes on others suspension parts. Not been able to jack the car up and take a look today, will have to wait until next weekend now, I can't see anything obvious, weird!

Yeah that definitely sounds like a different issue. None of the bits you have replaced will cause that.

Problem solved, both down to schoolboy errors.
No lube on the ARB/Powerflex bushes, as they didn't come with any for some reason I didn't use anything and the ARB was bound and couldn't twist. Thanks to Andy @ APM for advising me over the phone what I should have done.
The worst problem though was a real good one, I put the engine guard on upside down so it was touching the sump on one corner hence the horrific vibration from the engine.
All sorted now, thankfully nothing more than my own stupidity to blame, oops.
