Why don't GT3/GT2 have PSM?
 

I'm as enthusiastic as the next guy about "pure" performance but a fully defeatable PSM would be great for the street. I read somewhere that the system uses no special equipment and is software only so cost or weight should not be an issue.

Nobody? some debate?

wait til morning Tyson will have something for ya!

psm available on gt2
 

psm is an option on 2004 gt2...

Re: psm available on gt2
 

u mean pcm or psm? ;)

PCM is an option, PSM is not :)

Correct.

Re: Why don't GT3/GT2 have PSM?
 

For starters, why would you want PSM on a 2wd car? Second, with a car that oversteers, you want the slippage at the rear. Mercedes experimented with something like what you are talking about on the CLK models and it really didn't help to a measurable degree.

Correct me if I'm wrong, but the GT2/Gt3 cars have an LSD, which would drive any kind of PSM system nuts.

As to why you'd want PSM on a RWD car, there are a myriad of reasons why it would make sense on public roads in normal driving. Unexpected weather conditions (like snow on a bridge), gravel on the road as you make a turn, and idiots in SUVs veering into your lane are all things I've experienced, and PSM activation sorted it out. Chances are, at least one of those (probably the snow on the bridge thing - that puckered me up for a good hour or so) would have resulted in a nasty crunch. PSM is really useful when you're driving at less than 100% concentration, which applies to 90% of street driving (and, for some people, an unforgivable percentage of track driving)

PSM only has to save your ass once to make you a believer. I love the GT cars, but I will never again own a Porsche without PSM.


On a track, I would agree that playing with slip angles is the whole point, but most cars get driven more on the street than the track. Even then, not all of us can afford to stuff our 100k cars into the wall. I can't.

I'll climb off the soapbox now. I've experienced the effects of non-PSM car and PSM car, and for me, the choice is a no-brainer.

The best solution would clearly be a 3-stage PSM, with the full safety mode (default), the current PSM half-on/half-off option, and a fully-off you're-on-your-own-son mode.

A GT2 w/ PSM would be pretty much the perfect car for any Porsche fan, and it already is for a bunch of us.

The 40th anniv 911 has PSM and a LSD so they can be put together. One of the primary reasons I recently bought a Stradale vs. a GT3 is the lack of PSM on the later. It may sound pansy, but I do like having the safety net on the public mountain roads when driving aggressively.

Well said. I have plenty of rwd cars with systems similar to PSM and it is a wonderful thing.

Howdy!

I've been browsing for a several weeks, a 996/TT is high on my list of replacement weekend/track cars.

At any rate - something like you described below is implemented on the Z06 (Vette). There are two handling related systems, TC - Traction Control, and AH - Active Handling (both I think pretty self-explanatory :) )

You can run with both on, or switch both off, _or_ hold the button for a few seconds and TC is turned off, but AH is left on. This allows you to rotate the car on-track (hopefully you're doing this on track ;) ) but keep the AH - the DCI actually indicates "Competition Mode"

I've heard it reported that the Z06/V2.0 of this system actually desensitizes the AH sub-system while in Comp Mode. Gives you a bit more freedom on track, while still providing some a$$ saving, drive-the-car-home input.

Seeya -

Nope, mon frere. No, it doesn't.

You are a pansy Ben ;)

As Guy once said, PSM on a GT2 is your right foot.

I think you guys put way too much confidence in PSM. It cannot overcome the laws of physics and on the track it is downright dangerous.

GT2/GT3 are meant for competent drivers. If you guys like PSM that much, these aren't the cars for you. Besides, if you have a safety net all the time, how will you improve as a driver?

psm available on gt2
 

as stated earlier, psm is available on 2004 gt2's. call germany directly to discuss...
