Powerflex 306 Front wishbone kit - thiscocks - 30-06-2014
Hi
I just wondered if anyone had fitted the Powerflex Wishbone (front and rear) bush kit and what they though of it? The rear bush apparently adds a bit of neg caster.
I will be fitting (trying to) to a Citroen zx 16v which I think it should fit but will find out anyhow I guess!
Cheers, Tim

Excellent upgrade.
However the P bush can be upgraded a lot cheaper partner type p bushes...theres a thread about them somewhere
And make sure you have the updated front-front wishbone bushes
The little bits for the rear beam dont do a lot...esp when they fall out

P bush thread for you

RE: Powerflex 306 Front wishbone kit - thiscocks - 30-06-2014
ok, cheers. I guess the Partner P bushes dont have the neg caster built in?
RE: Powerflex 306 Front wishbone kit - zx_volcane - 30-06-2014
Was unaware the pwoerflex p push added negative camber?
pics of the 16v please
RE: Powerflex 306 Front wishbone kit - Piggy - 30-06-2014
Yeah, 4 wheel laser alignment showed that they certainly did, also added half degree of camber from stock by the figures...and the look of the wheels!
RE: Powerflex 306 Front wishbone kit - Tom - 30-06-2014
Remember the partner p bush might be better than standard 306 ones, but its still rubber so not exactly an upgrade when compared to polybushes!
RE: Powerflex 306 Front wishbone kit - thiscocks - 30-06-2014
cheers all, ordered the 306 front set so will let you know if they fit!
RE: Powerflex 306 Front wishbone kit - puglove - 30-06-2014
Tom have you used a powerflex and a 2012 partner P bush and compared the two???? Id personaly say the 2012> partber bushes are actually a better upgrade give you a better feel and tighten the steering up just as much as a ppwer flex!!
RE: Powerflex 306 Front wishbone kit - Piggy - 30-06-2014
Although, to see things equally, we need to give those partner bushes some time/mileage before we say they are so much better than powerflex
RE: Powerflex 306 Front wishbone kit - cully - 30-06-2014
1500 miles and a few trips round nurburg ring and stil going, enough
i like my partner P bush's

kerry's have been fitted for well over 1.5 years now
RE: Powerflex 306 Front wishbone kit - Piggy - 30-06-2014
Thought you only fitted kerrys like 6month ago?!
RE: Powerflex 306 Front wishbone kit - Tom - 30-06-2014
Sorry should of mentioned i havent used both, so my opinion is null and void, just a simple observation i was stating...

Mate I'm not sure you mean caster angle.
Caster is the angle of the vertical axis from the top of the strut straight through to the bottom ball joint around which the steering pivots and how far it is tilted to the back of the car. Negative caster would tilt the top of this line towards the front of the car.
To change this would require moving the wishbone (or strut top) further forwards or backwards along the car which on a 306 would require some serious modification to either wishbones or subframe.

RE: Powerflex 306 Front wishbone kit - Piggy - 02-07-2014
He is right in quoting Powerflex who say it will affect caster
RE: Powerflex 306 Front wishbone kit - puglove - 02-07-2014
But chris does have a point!

Not quite - it involves moving the balljoint pin part of the wishbone forward (or the strut top backwards)
If the front bush mounting point is static and you fit an offset bush to the rear (P-bush) mounting point, that'll twist the wishbone slightly around the front mounting point and have the effect of moving the balljoint forwards a smidgen, changing the caster angle.
RE: Powerflex 306 Front wishbone kit - Rippthrough - 02-07-2014
Yep, although, it also alters the anti-dive characteristics slightly, and with the pivots being out of line, increases the wear on the front bush...
RE: Powerflex 306 Front wishbone kit - Dum-Dum - 02-07-2014
Quite. It didn't stop BMW fitting eccentric P bushes to the E46 M3 when the rest of the range was concentric.
RE: Powerflex 306 Front wishbone kit - welshpug - 02-07-2014
whiteline do a similar thing on the classic subaru but in the opposite direction, lowering the rear pivot.
RE: Powerflex 306 Front wishbone kit - thiscocks - 03-07-2014
yes, sorry looking at your diagram I meant positive not negative caster (as per how Powerandtorque explains). I think this in turn gives more negative camber when you have lock on. There was a mod you could do to 106 Rallyes (my last car) to give it a bit of positive caster by rotating the struts. Made the steering a bit heavier but gave perhaps a tad more turn-in.
RE: Powerflex 306 Front wishbone kit - LewisG - 05-07-2014
P bushes are brilliant, easy fit, however, powerflex bushes are sh*t, they dont fit, I have the redesigned ones and they still dont fit, I had to modify it A LOT to get them to fit.
RE: Powerflex 306 Front wishbone kit - Piggy - 05-07-2014
Powerflex ones fit like a dream.
The redesigned ones took me about 5min a side to do!

Mine wouldnt fit, they were about 10mm wider then the gap they go into.
And when I put the metal cyclinder in, it was pushing the bushes out!
RE: Powerflex 306 Front wishbone kit - Piggy - 05-07-2014
You have the old design ones then.
Exactly the issue I had, and 100s of 306 owners have had. I just emailed powerflex about it, rather than cut it/bash and moan about it as everyone else has for years. They asked for dimensions, then redesigned it, sent me a set, and they fitted like a glove dipped in butter!!

I bought them off someone on here, Cant remember his username ill find out, but he said they were the redesigned ones.
RE: Powerflex 306 Front wishbone kit - Piggy - 05-07-2014
Got any pics?
Easy way to tell is that the mushroom ends to the purple parts...the old ones have a fat square edge, new ones dont and a metal washer moulded in
Dont panic if you do though...quick email to powerflex explaining and they will send you the new ones
