As I understand and have seen on YouTube, the front wheels may not buy you anything under most slippery conditions with the C4. What is it, I recall 35% max power to the front wheels? Still, doing a proper lift job, tall wheels, and painting it to the Rothmans scheme seems like a very cool idea. Would love to see that.

The plan is for this to be a budget (relative) so I'll be sticking with the stock 996 set up. That said having been driving my current C4 for the last two Michigan winters the system is perfectly adequate.
The only reason I stopped driving it is 12" to 18" of frozen crusty snow was starting to tear things up so until the roads are plowed I driving the Jeep.

Sounds like a great project. Someone did a replica of the Dakar 911 (technically a 953), while the suspension it very different, they might be able to give you some pointers. I believe that replica was a lifted 964. Also, random thought, but I think the guy who did it owned the Ferris Bueller house! I recall seeing some pics of it in a garage that looked just like Cameron's.
I see from your sig that you have a lifted Jeep (no such thing a WY though, I think you mean WJ!), similar principles should apply. I would look at adding spacers in the coils, and installing longer travel shocks. Some modified Jeeps use stock length shocks, which limit the flex. Also, don't forget about CV shaft angles. It it's too steep you'll be asking for breakage. Since you'll only be lifting a small amount most suspension geometry shouldn't change that much. However, remember that you may need to make adjustments with the steering, roll bars etc. to accommodate. Ball joints will likely see accelerated wear.
Good luck!

Thanks DK570, and yes my jeep is a WJ (typing never was my strong point lol), it has coil spacers (a lot easier on a solid axle).
I agree half shaft angles and length will be a potential issue. This is still just a idea and I will need to find a suitable C4 to modify I want to keep my current car pretty much stock.
I'm only thinking 1 to 1.5" lift and skid plates smaller rims and same rolling dia tires probably narrower I will need to look at available rims and winter tire sizes.
Certainly a lot of details with suspension geometry possible spacers / adapters or new brackets need to dig into the manual and get the current car on the ramp that may be a while as Gary has a V10 M5 (can't wait to spring to drive that) which is calling it home right now.

Not snow, but 35% does not help at all...
I'd think the positive lock up of the electronic clutch packs in a 964 C4 would make much more sense. Same technology as the 959.

That video is really irrelevant to the AWD capability of the 996.
Wet grass has same traction as ice. Staring uphill on the ice covered surface on the summer tires has same result in any car regardless of the number of driven wheels.
However, you are correct that 996's AWD system is not geared towards low traction/slow speed situations. The system was designed for high speed cornering, to help pull the car through the corners.
But, 911 already has a very favorable layout for off-road use. You have most of the weigh sitting on the rear wheels, and that in and of itself gives all 911s great traction. With raised suspension and chunky tires 911 becomes a buggy by default. I know most people don't drive their 996s in adverse weather conditions, but those who do will report that 996 has amazing traction in wet and snowy weather in the stock form. Physics of the RR layout makes 996 a grip and go car in any weather.

I'm glad I'm not the only one who has thought of doing this. I live on the outskirts of Phoenix and have been thinking about doing a Porsche rally project too. Lots of opportunity for dirt and off-road fun.

When we ordered ours there were options (TE?) for SS under carriage plates to cover the gas tank, engine, and diffs. There was also a 4" lift kit too. We had planned to do it at some point so we could freak people out driving it on the beach, but life happened before we did. I started looking again off and on a few years ago, but haven't been able to find the information again 
As I recall at the time we were ordering there was an article in some Porsche related mag about someone from Hollywood that did all that to their 996 C4 and drove it through the deserts out west. That would have been in the 99-01 time frame.
