Hello Folks

It won't be long before I need a clutch, was looking about and thought while I am at it would it be wise to get an IMS upgrade, been looking on RPM web site. Is it a no brainer to get it done or do some of you think against it. I am sure there has been loads about this but I couldn't see anything on it so wanted to raise it again.

Regards Phil
 
Hi Phil,

The way I see it the regular IMS is at least 95% reliable.
The LN IMS is lifed - you have to replace it every few years/miles.

Better to have an IMS guardian - the light comes on, you stop the car, you get it towed to a garage, you change the IMS bearing.
 
Available here for £275 as a DIY job.

I've met Tony the owner a few times, really top guy.
 
Thanks Rod

Maybe your suggestion is a good one. I didn't realise these had to be replaced after a certain miles / years.

Maybe to go with what you suggest would be the way forward.

Cheers Phil

 
I had my ims swapped for a ln by autofarm who i recommend. The information was the life was 45,000 but autofarm said they had t had one fail
 
Check out the Revolution Porsche website - they do several different IMS upgrades, including an oil fed one I believe.

As far as I know the original LN bearing had a recommendation to change every 40k, but there has been another LN bearing upgrade which is a dual row fitment for single row cars.

So many people seem to think after-market solution is a permanent fix.
 
I'm not sure that I would trust the IMS guardian to be honest, by the time there is enough metal to trigger an alert the chances are there are loads more pieces of metal going round the engine. Bad times.

Plus if you were in the outside lane of the motorway doing 70mph when the alert goes off, what are you going to do? By the time you've got to the hard shoulder the engines screwed anyway.

My view is why pay circa £300 plus for the guardian when you can upgrade & almost forget about the issue for circa £1k?
 
Why waste £1k when simply fitting a new OEM bearing is a perfectly safe option?

All arguments have pros and cons
I went down ln bearing ims replacement and will also add in guardian
The crux of matter is we have bought a car with risks as compared to turbo or 997 and these are just mitigating factors
 
If the IMS issue is really bugging you and stopping you enjoying your car, then odds on no words of reassurance on this or any other website will help.
If that's the case get it done and enjoy your car. with regards to longevity nothing is foolproof, but hopefully it should ease your mind for the foreseeable future.
Just my thoughts.
 
The ceramic bearing just replaces the perceived risk with another (real) risk.

When I replaced the clutch last year I was in the same predicament. Should I replace it with one that has a 95% chance of lasting 200K or one that should last a short while (on the US web sites there are a few that do fail) but will start to disintegrate after 40K.

After chatting to Sid @ PorscheTorque he fitted the latest version of the OEM bearing direct from the company who makes them for Porsche (it was less than £50).
I'm just going to treat it as a consumable and replace it every time I change the clutch.

I've slept better ever since 😜

I thought that a lot of the failures on the original bearing were at low mileages. If that's the case, putting another Porsche bearing in raises the risk in my opinion.
 
The number of failures is very, very low (regardless of the scaremongering on the internet).

The bearing is not a Porsche bearing, it is a third party item sourced for the production run, Anybody who wastes money on an unproven 'preventative measure' that is vastly overpriced is being ripped off. There are many cheaper and more proven ways of fixing this if it is a problem, but for most it is not a problem.
