There is no way after I did the conversion on my TT would I ever go back...ever. You can do it on the C4S as well, no worries it is reversible when and if you sell the car. I understand why you want to do it, you don't want a Narrow body car,or you would have bought one. I don't blame you the WB is way more aggressive looking.Don't worry about the how good the car works in the not so friendly weather, if you adjust your driving styles for the conditions you wont have any issues.Now stop reading and get out in the garage and start wrenching!
So its official, it is possible..

PSM still works perfectly, the front differential is on a viscous coupling and has nothing to do with the ABS sensors which remain in tact after the axles are removed. If you have tiptronic, its a different story, wont work. Just do a quick search in the TT threads for RWD conversion, it will pop up a whole page of threads.

A few guys on the TT threads had it done in 3.5 hrs from start to finish. Count on needing a friend for help to get out the diff and axles.

I'm actually talking this over with Stephen from Imagine Auto about doing this conversion because my car is going in next week for PSS10's and adj. sway bars at the local speed shop here in Peoria,IL. All would need to be removed before align and corner balance. Will let you know if it comes to fruition.

Rep Power: 260 
Less weight, yes. More useable power, questionable, useable is the key work, getting the power to the ground is the factor and 4WD often offers big advantages, four times the rubber on pavement. Better handling, not really only different feel. If you look at track statistics the 4WD laps consistently faster, even in the hands of less experienced drivers. However, many prefer the feel of the 2WD, and the "challenge" of 2WD over 4WD, more traditional feel. I see many posters who question 4WD and PSM as taking away the skill factor and unnecessary technology, yet they never want to give up their ABS.
Once it gets wet and/or slippery, especially a little ice or snow and the 4WD will far out perform the 2WD. Also, removing the system will involve the PSM in a 4wd car which is programmed for 4WD and may effect the ABS. Having had 5 2WD porsches, and now a C4 Cab I would never go back except in the case of an older car, I still want to get another 928 as a toy.

It is a different way of driving, but, as you said, even in inexperienced hands, one can drive it really fast.
