Hi all, anyone here used the psb bushes , seem great value, wondering how they perform, my car is my daily and doesn't get loads of abuse the odd spirited drive , but have a few worn out bushes now and was thinking of replacing them all with the psb kit at £180 for full car seems good value if they are of a decent quality but cant find much online about them, any advice welcome cheers.

I've got a full set of them, only the front half of the car has them fitted currently. All good, no problems to report with them.
I've used PSB on my previous car also, again without any problems.
-
Thanks mate I'll order them then

They do look good, have to admit I have been peering at them for a few years - their range has expanded a lot since last looked.
In the past I had bad experience with Powerflex bushes failing way too early, but Superpro are my favourite... but not their prices - I may need to go for SP front and PSB rear axle on the Mk5.

The prices certainly look attractive, buying directly instead of via distributor/dealer structure, however two observations.
- the front bushes don’t appear to have any offset (anti lift) to increase castor.
- best check the durometer as there is a lot of work to do the rear of the car and a hard rated bushing will likely cause more noise via the boot than you might like in a daily driver.

Thats why i am going for Super pro front

At 180 for a complete car set, I'm considering getting a separate dedicated antilift kit, still works out cheaper than buying some of the more well known brands

We measured no change in my castor after fitting the SP arm kit with offset bushes. Still at 8 degrees on the nose.

I'm just looking to use the SP anti-lift inserts.
Something should have changed? I have fitted a few of their caster kits to older VW's they definitely move the wheel forward in the arch - if it was full arm kit don't they come pre-set down and outwards on each side?
-
Yes, the bushes were preset and definitely offset. Maybe their spec has changed or the geo of their arns differed? Also perhaps the oem bushes of my 2007 MY chassis were different to earlier cars?!?
I had a chat with their distributor about this and they were scratching their heads, however neither the subframe or the suspension had been touched between the before and after measurements. Anyhow the car does drive nicely with their firmer road durometer bushes. Out of interest, what castor numbers were you achieving after fitting their ALK? Mine is at 8 deg on the nose and iirc Pudding’s is also.

I'm still at planning stage for Mk5 - fitted camber correction to Mk4 and Lupo, different set up - Mk4 gone and not had Lupo on the road

Stock castor is +7.5 degrees with a tolerance of about half a degree. I suspect the SP anti-lift merely corrects any factory drift and gives you +0.5 at the most. If you end up with 8 degrees on both sides after alignment, call it a success at a reasonable price. Equal castor is more important than equal camber.
Offset bushing is not the best method to increase castor anyway. All the SP bushes do is push the rear of the wishbone outboard laterally approx 10mm, which ultimately means the front and rear bush alignment is no longer concentric, but it does kick the strut forward a tiny bit, but nothing like a full degree.
The best way to increase castor is to either tilt the top of the strut further back with adjustable top plates, or move the bottom of the strut forwards with modified knuckles. The SP offset bush method is a half-baked bodge that won't ever give you a full degree of castor.
The SP consoles do improve the front end feel and grip quite a lot, but it's purely down to the wishbone not moving around so much compared to the stock bushes, rather than the claimed castor increase. If there was an appreciable castor increase, wheel hop would reduce, but it doesn't.
