Should I be turning the traction button off when I'm on track?
At Car Limits Andy told me there were no benefits to doing so but that may have just after seeing my lack of ability!!
PS I have a 997 GT3

Are you pushing hard enough that the TC is actually doing anything? I've heard that it can put a lot of wear on the rear brakes. If not, then leave it on - it may just save you one day. I scarcely ever see the TC light flash on mine so I'm happy to leave it on.

Sport button gives you a bit more movement before it kicks in though if you want some middle ground.

For track and road I always use the sport buton. Maybe I need more space for run offs b4 I deactivate the t/c.
I was watching Chris Harris clip in he's 4.0 RS with him sideways with TC off.
Happy to have a go :-)

I heard that PSM can wear the brakes as it may apply them to keep stability when you are driving hard.
Not good for expensive ceramic rotors!

So when I went to donny recently in my cayman s I decided I would switch it off to save disc wear...
My first track day I had loads to worry about (tyres, engine, brakes - oh and crashing) so thought this would lighten the burden, especially if I just take it easy.

So on the first sighting lap I switched it off after craner curves and it was back on before the next bend! If you have even had the rear step out on you it is ferocious and I'm not sure I could catch it without PSM. I didn't want to find out on my first trackday so it went back on again.
I figured if I can take it easy for PSM (or lack of) then I can take it easy for engine/brake/tyre wear.

Having the sport mode on was enough and I found you can only do a few laps anyway before the tyres start to lose grip.

I hear you. Not like you getting paid to be the quickest and most flamboyant out there is it. TC it is!!

Either it wasn't dry (in which case it's more understandable) or there's something wrong with your car, or how you're driving it (in which case get some instruction). I instructed someone on his first ever track day in his Cayman S at Oulton Park in the damp a few years ago, PSM was left turned on but never cut in all morning whilst he drove - I then did a few "hot" (that that hot really, but a fair bit quicker than he'd been going) laps and even on a (by then) wet track PSM never kicked in at all - I'd not driven a Cayman on a track before and I was really impressed with how balanced it was and its capabilities without the PSM ever troubling us.

I suppose my point is; sure, leave it on as a safety net, it's unlikely to cut in anyway unless you're driving the car in an unsettled way - and if you are, get some instruction to learn to be smoother. smile

I thought the TC button on the first 7GT3's was just a throttle cut off like the older 996's?
PS, I know what PSM does, and I love the sport setting that lets you go a little bit sideways with the comfort of knowing it will cut in again if you dont catch it, lets you learn a road/circuit so you can turn it off knowing when you are going to reach the car's limits the next time around.

I wouldn't expect that to happen, not a driving god but done a couple of days in older cars that don't have the luxury of TC and never been an issue, even in the rain.

Interestingly we had a couple with a new Boxster on a recent drive out and they were complaining about the tail end being happy with TC off, it was a baking hot day. I suspect there was something wrong, maybe tyre pressures?

My parents MX5 can wiggle its arse in quite a scary and unexpected way when the tyre presses are off and mismatched, and it doesn't have Porsche levels of power.

Note that PSM kicks in braking even if you turn it of. This gives slower throttle response out of tight turns. Some cayman and boxster drivers have installed cut-off switch to yaw sensor to prevent PSM turning on in track driving.
