Hi everyone, picked up my 07 GT3 on Saturday and loving it so far.
Just a bit of a concern, when I was reversing it into my garage last night (up a slight hill and on gravel) the clutch seemed to be slipping. Almost to a point where I had the clutch completely up to nurse it over a slight hump as you go into the garage.
There was an aweful smell once I had finally got it into the garage. It seems to me like the clutch is slipping, does this sound right? If so, where do I stand with the OPC? Its got a 2 year warranty but I assume clutch isn't covered.

Hi, clutch slipping won't be covered under warranty, but you may have a case to go back to your dealer and at least get a contribution from them if it needs a new clutch. What's the mileage on your car?
I had mine done a few years back on my 07 GT3 also, was having an RMS done under warranty so I just paid for the parts as gearbox was coming out anyway. Mine had done about 20k miles, the friction plate that came out was worn only a little so had plenty of life left - cost was about £1k for friction plate + pressure plate + bearing, then another £1k for flywheel (mine didn't need a new one), and at least another £1k for fitting. This was not UK OPC prices but a rough guide - may be +20% more than the above (was a vat free country).
Have you seen it slip in gear, say suddenly flooring it at 3k in 4th gear?

I'm taking the car to work tomorrow so when I get home I'll try pulling it into the garage forwards instead.
It does just seem to be in reverse and it absolutely stinks when it does it. It doesn't really smell like I would call conventional clutch smell though, hard to explain the smell but doesn't smell good.

My 996T does this as well, but it has (supposedly and probably) recently had a new clutch. I would say that these cars don't like the clutch being slipped as we all tend to do when performing certain low speed manoeuvres. Or perhaps it's a "recent clutch" thing. It seems mine used to stink more, or perhaps I just do this less...It does just seem to be in reverse and it absolutely stinks when it does it.

Mine judders in reverse and sometimes stalls if the revs are too low.
I understand that the limited slip diff offers more resistance when pushed backwards and hence judder/stall. I guess that if the clutch is starting to slip the extra load of being in reverse will make it more obvious?
If you floor it in 2nd or 3rd this should obviate the problem, probably!

I had the same the first couple of times i drove mine, tried reversing slightly uphill into my garage & would either stall or get a clutch smell... The gearing seems high in reverse & suspect it was technique rather than the car because it's been absolutely fine since!
Hope you're enjoying the car....

I have occasionally slipped mine in reverse too and it smells, so rather than ride the clutch try to fully release it.
For all those that have shudder in reverse, you shouldn't have. Mine did and after I changed the clutch and flywheel it totally eradicated it.

If you believe the clutch is slipping using 1st or reverse gear is not the best way to test for a slipping clutch.It does just seem to be in reverse and it absolutely stinks when it does it.

Drive the car around until everything is up to temperature.
On the road -- where you have some room -- put the transmission in 4th or 5th gear. At around 2K RPMs floor the gas pedal. Hold it for as long as its safe. If the RPMs climb with no increase in vehicle speed the clutch is slipping.
No need to test this again. The clutch will not get better on its own. Time to replace the clutch and any associated parts the tech believes need replacing.
If the clutch is not slipping then something else is going on.
I suspect it is driver related. Reverse gear is higher than 1st so the same gas pedal/clutch release technique that we know so well for moving the car away in 1st doesn't work so well for reverse.
Either the clutch gets slipped excessively or the car judders and bucks from a too quick engagment.
My advise is to avoid backing the car up any more than you have to to avoid excessive clutch slippage.
Also, if it hasn't been done in awhile (should be done every 2 years) get the car in for a clutch (and brake fluid) flush and bleed. Past its flush/bleed by date clutch fluid can really affect clutch operation and shifting.

I hear Alpinestars rides the clutch around town...still has not passed driving test 
I've had a clutch go early....usually can be the prongs failing on the pressure plate causing the release bearing to fail ...if the prongs fail then you lose your clutch pedal.

k your flywheel tooThanks for all the replies. I think a lot of it may have been to do with me not being used to reverse being such a long gear and probably riding it a bit to manoeuvre. It seems much better now I've got used to it, I will test the floor it in 4th, 5th gear later but pretty sure it will be ok.
As a side note, I now have another smell which smells like a saw mill. You know, the smell you get when cutting wood. Very strange.

In terms of the reverse judder, mine has always done it, with both clutches. I didn't replace the flywheel on mine, but a small layer was taken off the surface, I've not seen any slip in reverse, and no clutch burn smell ever in over 4 years of ownership. My reverse technique is to slip/ride the clutch as little as possible, depends on the gradient and distance to be reversed. If I can get the car moving by slipping the clutch slightly then coast to the final position, that's what I will do. If a longer distance then I will allow full engagement of clutch and leave it engaged before coasting to standstill.
One concern for me is the factory diff, has anyone had one replaced under warranty if it's not performing as it should? Do OPCs have the ability and processes/tools to check a GT3 diff and measure it's performance to factory spec?
