997.2.GT3 Does changing coilovers give a PASM error?

Hypothetically speaking: If one was to replace the coilovers on a 2010 GT3 with something aftermarket, would it cause any problems other than the button becoming redundant?
P.S. Thanks Maximtaylor and NXI20 for putting idea's in my head :D.
 
You will get a pasm failure, which will prevent you from engaging sport mode

Unless you get something pasm controllable or properly disable it
 
Thanks for the answer. Do you know if that's something that can be turned off with Durametric? I was wondering if it was worth investing in the software anyway.
 
I would imagine the fault code could be switched off ok, have you had a look on rennlist to see how its been done in t he US ?


What are you thinking of putting on there?
 
I've had a quick look on Rennlist, but my search terms didn't result in much.

I have just hit the button on a set of Ohlins 8)
 
Nice. Id be really interested to drive mine on a passive set up. What are you after that the pasm wont do?, i know its not the b all and end all but the car is pretty capable on a circuit on the std suspension already.
 
I beleive piwis or durametric will allow you to tell it pasm is not installed which solves the issue
 
Mark: Cheers, I had a quick read up on the Durametric software, and it seems useful, so I've got an 'enthusiast' pack on the way to me as well.

Senoj: I recently did the Destination Nurburgring 9 trackday, and the car was great! However I made the mistake of going for a lap in Max's Manthey 410 996 on the Manthey valved KW V3's, and it felt quite considerably more composed over some of the rougher parts of the track than mine. There could obviously be a lot more to this than just the coilover units themselves, but the car has roughly the same power and tyres, and from the passenger seat at least felt very different.

I've specced the Ohlins for combined road and track use, as I still daily drive the car. We'll just have to wait and see if fitting them is a backwards step for normal road driving. I'm confident it will make a substantial difference on track.

Now I just need to get the slightly tired diff sorted. I'm still waiting for Guards to get back to me on rebuilding mine to their spec.
 
Phil, i was at DN9 too. Were you leaving PASM in normal rather than sport? In sport at the ring its pretty torrid for about 70% of the lap. I leave it soft on the RS.

My thinking is Sport Auto drove a .2 GT3 round the full circuit in 7.40, if you are getting close to that then maybe some fun can be unlocked with a passive set up. But on the road the PASM is a pretty good compromise and any set up is going to be a compromise of some sort.

As i said though, i would love to try passive and active stuff back to back but i suppose i just dont fancy throwing the £'s at it :lol:

Regards diff, just get JZM or someone to fit a cup diff plate set, job done and should be under a bag o sand.
 
Ahh cool, sorry there's always so many GT3's there I lose track.
Most of the time I had it in sport, but I did give it a go in normal for a couple of laps. I (perhaps wrongly) presumed that the quoted best lap times would have been done in sport. If not, what's the point of it?
In no way would I ever suggest I'm anywhere near reaching the full potential of the car with the current suspension. I'm just looking to cheat to help me get the best out of the car as a whole :D.

GTGears / Guard have got back to me, and will supply the parts I need to a spec that suits me for $1500, and I have to build it. It sounds like quite a lot to me for some parts, but everything I've read says it's a better choice than just the cup plates.
 
Best production GT3 997 lap times on the ring have all been set in normal mode, track is just too bumpy for sport. At a smooth circuit like Spa then yes, sport mode all the way.

I am pretty sure those with passive adjustables are setting them pretty soft there too.

The Guards is a good product but i honestly dont think its worth the hassle for us in the UK as there are plenty of specialists fitting a cup spec diff with good results for reasonable dosh.

I have a 997.1 which is running Motons. The 997.1 has two buttons one for PASM and the other for sports mode. If you remove the PASM the code error can be removed and on board computer needs resetting. Sports button is not effected in any way and works fine.

Hi Phil, glad you're doing some real mods, not just cosmetic fluff :)

Confirm that the 'ring needs soft damping (I use what I set the Motons to for the road, which is 2 off full soft on bump & rebound both ends). It also doesn't pay to have the springs too stiff either (BTDT). Jon & I are both on 100N/mm F & 140N/mm R and that seems a pretty good compromise for street & track, even using slicks.

Ref the Motorsport LSD, I have had loads of use out of mine (about 4.5 years, 65K miles & 110 trackdays). It still works fine but is getting a bit tired plus I want to increase the lockup %ages next time so it will be changed out for another Motorsport pack soon. I'll be talking to Matt @ Guards ref some different gear ratios though...

Spa :thumb:

...Or anywhere else except the 'ring for that matter. I've tried using sport and most of the lap isn't too bad as long as you know the line with the smoothest tarmac (most don't - even some of the very experienced drivers who turn in faster laps than I), but there are a few places where it really doesn't seem to work for you at all (and all of them are fast sections) so I generally drive it in soft too. A 996.2 GT3 on stock Bilsteins rides the bumps better than the PASM dampers (in either setting) on the 997 at the 'ring though (IMHO, but the rest of the out of the box 996 chassis is markedly inferior).

I am still a very long way from replacing the dampers on my 997.2 personally but I will look forward to hearing how you get on with the Ohlins - a CSL jockey that I know recently fitted a set and says little other than to rave over how much he loves them. I don't as yet know how they will be on a GT3 though as I haven't met anyone else who has tried them.
 
I wish I could have made dn9, next year hopefully I can go.

Reading about modifying the gt3 makes me depressed
:sad: I want to change a few things on mine but just can't afford too :frustrated:
Recession sucks.

What kind of times did you manage Phil??
