PK part number is the newer dual density Polylast bush. Personally I'd (and will be when my IMS hat goes in) go stock ford front. The IMS hat will stop the uneven side torque load that kills the lhf bush.

Have you had yours installed and who/where did you get it done?

I am pretty sure that Luke will be doing his install, if he hasn't already done it.

I know I'm reviving an old thread here but having just replaced my CAT600 bushes with the IMS kit, I thought I'd share my thoughts on both setups.

 

The CAT600 setup with Nolethane bush served my well in my Kenne Bell supercharged XR8 for about 6 years and 50,000 k's with daily driving and the occasional thrashing. There was increased NHV as was to be expected from such a stiff type bush, but it was not unacceptable.

 

Recently the CAT bushes had enough and thrashed out so I replaced them with an IMS diff hat kit with the Superpro bushes and I was very surprised how much quieter it was compared to the old bushes, even when they were new.

 

The car also now has zero axle tramp which it still did have a little bit with the CAT bushes and running Shockworx coilovers.

 

So the CAT bushes were good with the standard layout but the IMS kit, I think, addresses a basic design flaw in the original Ford design with out really increasing NVH. I'm very happy with it and recommend it.

Good review. I'm guessing manual as your complaining about axle tramp?

[FrogXA]

Thanks mate. Yeah, car is manual. Axle tramp was very mild with the CAT bushes but noticeable. No tramp at all now, it either grips up or spins the tyres but no bouncing up and down.

Good to know that. thanks for the feedback. I now know what I gotta do.
