Should I fit Powerflex bushings ..... or not?

[Ireland]

I'm planning getting a few jobs done to the car over the winter months.

One of them is to see about replacing the suspension bushings.

The original rubber ones are looking a bit perished.

There seems to be a very clear YES / NO divide about the Powerflex bushings.

What do you all reckon about them?

Are they worth the cost / effort?

well worth doing ,but a right pain in the asre !!

You'd have to be nuts not to fit the powerflex bushes imho.They're easier to fit,perform better,last longer,and should the need ever arise,will be much easier to replace if already fitted.

I'd be interested to know how long they last, I've fitted polyurethane bushes before (to other cars) and they didn't seem to last too well. Could've been an individual case, hence the question.

Apparently the Cerbera isn't as hard on its bushes as the Rover V8 TVRs, due to the (relative...) lack of torque at low speeds.

As far as I know, my car is still on its original bushes and they seem ok to me after 128k miles, but I've probably just got used to the slackness .

The rubber ones closest to the heat on my griff,lasted just 10-11k miles before starting to disintegrate!Whilst others nearby werent so bad,you could see that they were on their way out,all the same.The powerflex ones i have,have not been on much longer,but are still perfect at the moment and judging by others experiences that i have heard of, will be on for a much longer time.If they only lasted the same length of time,i'd still fit them purely for ease of replacement!

Polyurethane all the way, just make sure that you get the same stiffness / shore hardness as the original rubber type otherwise it becomes too harsh

Mine came with heat shields for the ones nearest the exhaust manifolds.

I sell the powerflex bushes and they come with heat shields as standard where needed.

It's your fault I even posted this question.

I just replaced a powerflex on my chim nearest the exhaust. After 2 years all that was left was the inner metal sleeve. But I have put in another poly as they are so easy to fit.

I ordered them today along with a new set of bolts for the suspension from Steve Heath.

Guess what I'll be doing on a number of evenings over the next few weeks .....
