I may be wrong Dan but from previous posts on here the poly RTABs are bigger and you cant run with the turner limiter kit.

i had powerflex bushes and OEM were put back in when Murketts replaced some of the rear suspension under warranty, unfortunately they didnt last a year so now they are fitting the limiter kit for me, I wont be able to claim on warranty if the RTABs go again but even Murketts say they make a worthwhile difference, I will let you know

I hope not! Check out swift springs.:thumbs:

In a word Dan "No" ;) Still running O.E. RTAB that were replaced under warranty just shy of 60K miles. I do have "POWERFLEX" ones on standby :thumbs: when the replacement O.E. ones finally give out ;) :hahaha:

THANX mate :thumbs: I'll file the info.

Matt, why bother when the limiter kit offers OEM comfort but much controlled movement making the bushes last 3-4 times longer. Haven't touched mine in over 3 years and 30,000 energetic miles.

KW Clubsport :thumbs: :whistle:

+ 1


new range will have handy twisty adjusters for much easier access

Will dig out some pics

Simpsons did me a limiter kit along with brand new OEM RTAB's last April Steve, it made a huge difference, shame it feel's normal now! I need to tweek something again to make it feel more special again! :hahaha:

Rob/Daz, what's the deal with these new KW Clubsport's out then, what's new and improved over the old range barring adjusters? Oh, and any word on price yet?

Any thought's guy's? :thumbs:

The rear trailing arm bush is designed to be sideways-compliant in order reduce the toe-out on the rear wheels under hard cornering.
This is in order to reduce oversteer.
More toe-out on the rear = more oversteer.


The RTAB limiters effectively stop the rear toe changing during hard cornering by stopping the RTA from moving sideways.

What everyone calls "tightening up the rear end".

But it will increase the tendency to oversteer.


So I'm in two minds.

I am running these ATM and they're ok. But I haven't tracked my car to see how good they actually are, although simpson rave about them they say you don't even need to change your oem ARBs, the limiter kit will be suffice even for the track.
