Poly bushes for front ARB - worth it?

Is there really any point spending £30 on two bushes rather than £7 on OE rubber ones?

My car has 90Nm front springs but a standard S2 ARB. It doesn't roll much. The PCGB race cars still use rubber bushes don't they?
 
Mines poly bushed Ed, I think you would notice the difference.

BTW I'm heading back to the UK tonight and will be out your way on Friday 4th, marshaling a rally, so if those springs are still available?

Thanks Gerry

At the moment I'll be around on the 4th - hard to be certain as client visits often get arranged at reasonably short notice. I'll stick you in the diary & aim to be at home that day [:D]
 
I polybushed the front ARB on my last car and am about to do the same on the current one.

I used the orange Flo-Flex bushes from eBay and they were really good. The current ones are a bit worn and one is very spongy due to a slight oil leak - I'm not planning on attending to it until I do the belts at the end of the year so a polybush will resist that too.
 
The cheaper bushes can squeak or in some cases crack. Those sold by SuperPro/Superflex (the same firm bar the latter using Stainless sleeves on their bushes) and Powerflex seem to do the job well on most cars I have tried with them.

My 951 came with Poly bushes, but I would probably go with them again to save changing them (a leaking crank seal or power steering fluid will soon ruin rubber bushes (they were shot on my S2 due to this). That is before you mention oil changes where oil from the filter seems to work its way down despite stuffing the area around the filter with the world's supply of rags). I guess one way around this is to ensure one has no leaks, but then again you never know when a PAS banjo washer etc. will leak.
 
I have done the whole car and nothing creaks. Flo flex where fine for the ARB but they were not right when it came to the wishbones (too short) the rest of the car was done with Powerflex.
 
Hi Ed. See you on track at some point soon hopefully[:)]
I have Proflex poly bushes on the front ARB. No squeaks in the 5 or so years they have been on so no real downside IMO. Do they work? Can't really remember a dramatic improvement when they were fitted but they are purple so match the KWs nicely[:D]
 
Poly bushing is allowed this year,solid top mounts also,got mine from Lindsey racing,feels much sharper than before,like a delay been removed from front end,felt good before but better now,would love to do it to my red turbo.
 
Solid top mounts can wait.. (spending too much on cars at the moment)

The 944 should be done in a couple of weeks - I presume yours is all OK now Steve?

I'll be doing my next trackday (cadwell in april) and Rutland in the Boxster - hope you won't disown me..

I bet the cars feel a lot more "pointy" now mark.?
With slicks and all....
Are you allowed to fit lower chassis braces yet.?
And poly/solid castor mounts.?
 
I saw the lower chassis brace on LR and really would love to fit it but I am pretty sure it's against the rules[&o]
The castor mounts have to be standard [&o]
Everything else can be poly bushed now which is something.
The solid top mounts do as you say make the front end SO much more pointy was very pleased,the original top mounts were taking a pounding and they are not cheap so I was glad the rules relaxed a bit.The slicks under race conditions are hard on such an old car and 968 parts are not getting any cheaper.
