I went out to move the car this morning and noticed a bit of what looked like a bush on the ground, got under for a look and sure enough theres a couple of bushes starting to spontaneously disintegrate.
They're all the same brand and age, Whiteline, about 7 years old >5000km's, so looks like I'm going to be replacing the lot.
 
So what are people using? any recommendations? Don't care about cost just want quality parts that won't fall apart. 

Ahaaaaa I say Drewdog.
Had my last RS off the road for a few years as it was going to be the Cossie recipient.
When I changed my mind, I put it back together and on the first outing got a terrible clunk and thudding from the rear.
Turned out the sway bar bushes had disintegrated.
I never remembered what brand they were. They were a light blue colour though.
At the time (2014) I did some asking around and it seemed there were one or two brands with dubious raps.
Since then I have used Nolathane and Superpro. No problems to date.

I've just been out to the shed with a beer to lament the situation, picking at some of the bushes they have the consistency of mature cheese, I like a good cheese but not holding my car together
I picked up the Whiteline stuff from the same shop I got my rear leaf springs from, he had them in stock and it seemed like a good idea at the time.
Yeah from what I'm reading Nolathane and Superpro are the way to go. I'm leaning towards Nolathane as they were on the car when I rebuilt it and were showing no signs of deterioration at 15+ years old.
The tricky one I'm having trouble finding is for the original sway bar to diff bush. 
Superpro are saying they do them but are only listing the oversize ones. I guess it'll have to wait until I can contact them during the week.

+1 for Nolathane. 

I put nollies in my lowered leaf springs after I snapped a stock one and had nollies in the front sway bar and steering rack. That was when it was on the road like 18 years ago. When I pulled everything apart over the last few months they still look like new. 

Funny Marka should say the blue ones went like chalk, a mate had the same thing on his rear bushes, clunk noise and leaving a blue patch of crumbles, new bushes time..
