Was thinking those Cat600 fronts. Was in a car the other day with them and the nolathane rear and was quite ok noise wise. Just a little diff whine.

I had the CAT600 bushes in my GT and they were pretty noisey on an otherwise stock car. Like, unnecessarily/too noisey for a daily. Lots of clunking and diff wine. Literally ZERO tramp though!

If you've got surge pumps, an exhaust, horny turbo noise etc then you're less likely to notice (I.e. I went in Dan's old FG XR8 with the KB blown aluminator motor in it and that had them in and couldn't hear a thing from the diff over the blower and exhaust).

I heard his "TerminatorS" TS AU drive past one day on Toodyay Rd.  Relatively epic noise just cruising through the intersection, doesn't do things by halves.

Same motor, just with a blower instead of twin turbos and in a different car. Noise from that thing was insane! I have this vivid memory of him stomping on it (on a private road) and the thing lighting up and fighting between gripping and slipping as it slingshot into high triple digits all the while he's sitting there calmly telling me to watch the tacho needle "watch it, watch it, watch" as the thing revved out to like 7k! Fastest car I've ever actually been in and think it was "only" running like 530rwkw at the time. Definitely doesn't do things by halves!

Ugh I love the 5.4 it just needed boost so badly

Was that the one with the 6 litre block?

4.6l aluminum modular

^Correct.

Yeah a Ford Mustang SVT Cobra S/C engine that the US team who created it called the "Terminator".

 

Sounds like it was crazy to ride in.

Who in Perth has fitted one. Are they quiet and what front bushes did you use. Got to do my diff bushes but being quiet with no vibrations is No1 for me. And need to check how close my twin 3" manta exhaust will go to the hat mounts???

 

Anyone in Perth can take me for a drive or better yet let me thrash their car on a test drive.

 

Mine is probably just as quiet as the standard bush setup. If not quieter.. 

 

I used Cat600 front bushes (pictured below) and replaced all of the others with Superpro bushes.

I'll be trying standard bushes...will see if they hold up to the hurt locker that is my car's rear end with the IMS diff hat fitted.

 

Ah it's not really that bad, I try not to beat up on it too much in all honesty.  Try.
