Hey guys i was just wondering how you get rid of the diff bounce/bang under hard gearchange?

I think you can get some kind of bush upgrade for your drive shafts, I recall them being quite cheap and from peddars.

Is this common? maybe its just the diffback exhaust bouncing off the driveshaft end near the diff.. it had signs of it but i had never heard any loud noises until now and had heard rex's make the noise?

Had an argument over who's lane it was with a new SS, i won. First time ive really had to use the whole tacho up a few times

Didnt even do a proper launch, took off normal and gassed it up.

As far as I know its common. Mine used to do it under heavy gear changes everytime.

I remember posting the exact same question on the old forums and got the reply I gave you about the bush thingoes from peddars.

You can get a bushing kit for the rear shaft/diff to stop the banging, whiteline do one.

However, this will make the rear diff seem very very loud, especially under decelleration.

Speak to RMS for more info.

I've personally never experienced diff bang or bounce in my WRX...

get a set of the pineapple bushes, they cost bugger all, it'll fix the subframe movement causing the bang..
