PTV for CGTS - Page 1 - Boxster/Cayman - PistonHeads UK

I have a a deposit down on a Cayman GTS and have decided on X73 suspension and PCCB. Would PTV be a worthwhile addition? The car will not be tracked and I am a very average driver, however I was highly impressed with the overall feel and turn-in of the demonstrator thus equipped at Kendal OPC or do all CGTSs feel this good irrespective of PTV or not? Thanks

I would spec ptv again. I bought it mainly for the LSD, and didn't really want the torque vectoring part on entry to corner. Having said that I think it's brilliant. I don't notice it 'working' not in the same way as psm or TC is intrusive - it just somehow magically removes all trace of understeer Definitely a worthwhile addition with x73

Thanks for that. Are there any problems with increased brake wear?

Thanks I asked the senior driving consultant at the Silverstone Experience Centre and he told whilst PTV is by no means essential it is "icing on the cake". If you drove two cars one with and one without you would feel the tighter turn in and reduced understeer (due to selective rear braking) and better grip coming out of corners (thanks to the LSD). I specified it on our Boxster GTS, also with PCCB.

I'm new to Porsche, and didn't spec the Carbon Ceramics on my M3, because all Porsche and Ferrari people I know replace the carbon ceramics with steel if they do serious tracking due to the cost of replacing rotors. Any thoughts on that? Also, is the LSD revamped compared to the ones in the 997 and 996 GT and non GT cars where the diff would wear out after a couple of track days. Has it been reinforced?

Yes, I do plan to track the car. However, it won't a regular event so to speak. I am also fully aware on the replacement costs, as I went into this choice with all the facts and figures in mind. I don't know about the LSD, so I am unable to comment.

Milnsey said: Thanks for that. Are there any problems with increased brake wear? My instructor at the Silverstone experience centre mentioned extra brake wear. I have no personal experience but I find it hard to believe that the modicum of extra braking needed to reduce understeer could have a dramatic effect on brake wear.

Will have to take another think of it, but I think doing 8 track days / season I'm a bit worried about the PCCBs, although the lack of brake dust and endurance certainly has it's appeal.

I doubt it would have any more effect than the intervention of PSM already has on rear pad wear, marginally more possibly?

At the risk of stating the obvious I guess the harder your drive the more wear will occur as the PTV intervention will be harder and more frequent - but if you are driving harder brakes, tyres etc will experience more wear anyway irrespective of PTV.

Just to resurrect this thread again, can anyone enlighten me on whether PTV is active at normal cornering speeds or does it only come into play at the limits of adhesion when PSM is about to kick in? Thanks

Thanks As I understand it PTV (the rear braking bit) comes into play WELL before the limit of adhesion to aid turn in. Given that it is easy, without even thinking you are trying, to register .8g on roundabout I would expect it to come into play quite regularly in normal driving. I don't have PTV to confirm that though.

I have PTV on my BGTS, pain in the ar**. Had a couple of days down south last week went from Minehead to Lynton and Lynmouth via Porlock hill and the PTV kept kicking in around the tight bends on Porlock hill resulting in the car dragging the inner wheel around the bend. If I was to spec another Porsche this would not be on my list unless it was free and you could turn it off.

If you turn off PSm that should turn the. Ptv off

HokumPokum said: If you turn off PSm that should turn the. Ptv off That's fine on the track, not sure I would turn PSM off on the public roads though unless you are pretty good driver. It's quite an eye opener when they demonstrate PSM on and off at Silverstone, the instructors there strongly recommend not turning it off other than on a track!
