Just cut off the spindles from the axles and used those for the wheel carriers and removed the diff and driveshaft

An AWD Porsche has a greater tendency toward understeer as well.
Removing the AWD system makes the car lighter, and thus faster.
It's much cheaper to buy a 997.1 Widebody and do this conversion than to buy a 997.2 GTS.
It's also completely reversible to go back to stock AWD, whereas doing body mods will make the car less valuable to the purist at resale time.

If anything ever happens to my RUF C2S, I'll be shopping for a 997.1 Turbo, modding the intercoolers, turbos, suspension, and doing this RWD conversion to create essentially a GT2 for $50,00-$70,000 less.

Point 1 alone is worth repeating. I don't know how different the feel of a RWD 997.1 is from a RWD 997.2 but coming from two C4S's to the RWD GTS was a real eye opener. I knew there would be a difference but I had not anticipated just how different they would be. Your description of how it's different is spot on imo.

Bad drivers make understeer and 911s make understeer when driven improperly. C2s inherently do not want to turn in due to lack of weight in the front so Porsche suspension wizards use geometry and grannies to help the general track neophyte consumer with understeer. Trail braking has historically helped others, especially those setting cars up neutral for track and before the wonderful, albeit annoying world of electronic safety nets.

Turbo mushy feel is due to suspension set up and it is made to feel "plush" as it is Porsche "luxurious rocket ship."

997 GT2s out of the box has a large amount of understeer (light front, more neutral setup). Trail brake is your friend. Complaints about GT2 oversteer is more by virtue of throttle oversteer.

At the end of the day, I doubt most are even close to the limits anyway so any understeer complaints would be driver error.

A GT2 is more than just ripping out the AWD system.

Yes, though the engines are based on the same Mezger platform, I'm sure the GT2 has some different internals, but changing the turbos, suspension to TPCs Tractive DDA coilovers with their DSC box and a full RSS kit, the rear wing, retuning it, and doing the RWD conversion would get you 95% or better of the way there for much less money. The suspension would actually better than stock and fully active, plus you'd still have usable rear seats, and far more luxurious cockpit. Would it be a GT2, no, would it be damn close, you bet, and probably even better for a street car.

Can someone please link me to the correct place to order the RWD conversion? The one from this thread does not take me to the right place. Also, would this conversion work for a 997.1 C4? Description shows C4S.
