Retrofit PSM????

[loki_ut]

Here's a question right up Loren's alley. Is it possible to retrofit a 2000 996 C2 with PSM? I would be suprised if you could, but if so, I may have found my new (to me) Porsche.

Thanks is advance for any help,

Matt

Although likely possible - probably not practical from a financial point or time and effort. You don't have the wiring in the harness for the relays, switches and control indicator, the wheel sensors, the rate-of-turn sensor, the lateral acceleration sensor, the steering angle sensor, the brake booster pump, the DME program changes, or control module.

Oh well, i thought that would be the case. I had found an interesting car pretty close to home, but it a C2 without PSM. The car would be my daily driver. As I live in South Florida, severe weather can show up without warning. I am just a little reluctant to drive a 300hp car in bad rain without the PSM.

Thanks for the quick response,

You would be fine without PSM even in the rain. Not that hp really has anything to do with daily street handling, if you haven't driven a car with 300hp, you will find it is surprisingly little...

yeah, after about 4 mos or so, you'll start to think your car is slow and wnat something more :D

The 996's handle beautifully in the rain without PSM.

Just make sure you have enough thread in the tires.

I've driven two years in my 986S (first RWD car) without PSM and I'm blessed that the Boxster forgives a novice like myself. The point about good tyres is correct, the Boxster just snaps back in if you lift off the gas following a slide of the rear end under acceleration.

996 oversteering is surprisingly progressive. Your tail won't snap out all the suddent like a Boxster that has 50-50 weight dist. You can modulate the slide on 996 by slowing down and counter steer a little. In rain, just drive less aggressively than dry and you'll be fine w/o PSM.

IMO, PSM is actually more useful on a Boxster than a 911. I thought 911's rear weight bias would swring out and be uncontrollable without electronic aid given I have heard so many stories and based on common sense. However, if the rear tires are good, you won't have any issues. Don't mix your tire types BTW.
