Bloody awesome!.

Did the supplier give you any details as to how well these bushes will hold up in the AU IRS?

You're probably well aware that the standard design is poor and flog out the mounts real quick. Hopefully these bushes solve the issue!

Awesome. I was part way through a similar conversion to a set of worn mounts. What is the kit cost

Guys,

What are the symptoms of worn shock mounts, I have an S3 XR8, it appears to be travelling well at the rear. What should I be mindful of or listen out for?

Cheers

Maybe others had different symptoms to me, but the best way I can describe it- I kept thinking I had not fully closed the boot lid. I would pull over, get out and check it. All good. Hop back in go over a bit of uneven road and think, that bloody boot lid is not closed properly again. Took me a couple of weeks to work out where the noise was coming from.

Great,

Good to know, mine is solid at this stage, no adverse noises. My rear tie rods and link pins were shot, that helped stiffen the rear once I replaced those items. No noises or excess movement at the rear.

How many Kms on your car when it showed signs of wear/noise Crakrz?

[Xdesp80]

How many of you have done this conversion and are satisfied with the results?
Seems I am now up for the same repairs on my XR8.

Hi Everyone
How are these holding up for everyone? I have just got my diff rebuilt and changed the diff gears to 3.91 in my S3 XR8 but i don't hear any noise in the back just the front making a slight knocking noise reversing out a driveway but i think I'm going to do front to back.
If anyone needs passenger airbag clips just let me know.

The best way to check these upper mounts is to have someone drive the car while you sit in the back with one half of the rear seat down. With the cover already removed from the shock tower watch the top mount when the car is driven over some bumps. You will soon see if its stuffed or not.

I saw a T Series car on a club cruise on a freeway and the rear wheel was bouncing due to the shock mount on a smooth piece of road. The driver wasnt even aware of it. So don't rely on hearing a noise from the rear to assess.

There is another thread on these and the company that makes the replacements also does exchange with a deposit so if you don't want to tackle the swap and removing the rubber there is an alternative

Is there a company that actually dose a replacement for upper shock mounts?

No, the they have been NLA for a while now unfortunately. Superpro now makes the inserts above.

Pretty sure my XR8 still has the originals at 250,000km and they somehow are holding up ok...
