Turbo handling versus C2
My biggest concern when I finally decided to switch to 993Turbo from my 993 C2 was handling. The C2 is really crisp and fun on the factory suspension compared to all of the Turbos that I have driven which feel more Mercedes like in terms of smoothness but not as crisp and not as responsive. i.e. the Turbos seem to drive more like grand touring cars compared to the C2 My questions are:
Is the less crisp handling of the Turbo caused by the 4 wheel drive, the additional weight or by the stock suspension. I know at least one RLer who is removing all of the 4 wheel drive components to try and duplicate the C2 handling. Do you think that this will work? Is an upgraded suspension the answer ( there are lots of threads about M030, PSS 9 etc) ? Is there any answer or am I going to be chasing ghosts? Your comments will be most welcome.

993tt - AWD = RWD = point and shoot track weapon!
Removing the front differential, front half shafts and torque tube transform the car. New alignment settings are also needed after the AWD removal.

There's a very well put together 2WD kit by ViperBob. See here:

I will be converting my 993tt to rear wheel drive this winter sometime. I know how you feel. I went from a 993 C2S to this 993tt and agree with your personal findings. With that said, most of the suspension packages for your new 993tt will make a big dfference. Scan threads here on this forum to figure out which you want based on everyone's feedback.

All I know is the nut behind my wheel keeps going off track with the 4wd margin for error. I am assuming with 2wd we would have to revisit the part about driving 7/10ths.

I've only ever driven one TT. It may not have been a good example so I do not mean to offend but I did not like it. The GT2 is very different. Everything I love about old school 911's just a lot, lot more.

I will elaborate on my previous post... I was not aiming at anyone with that comment. It is just a funny saying. I was only pointing out that some can drive a high HP, rear engined car (certainly not me on track). It depends on the driver. I was referencing the post I quoted.

Graeme, I'm sure you do love it, but you've been driving and racing 911's of various stripes for a looong time, right? And (koff, koff) any chance of caging a ride in said GT2 at a 2008 track day?

Though along with the exhaust note, that is the one other thing I like better about my NA C2 993... the lighter steering feel. And no torque steer out of a turn.
I am getting used to it. The extra power makes it bearable
Still, I am on the fence on the 2wd conversion. Tempting.
Decisions decisions...

This topic was beat to death on 2 WD conversions. Note post #39 on 8/31/2007 good stuff I must say.
Brian, thanks for the complement, a nut is clearly a step up from a felon.
The PROBLEM with the conversion is your trying to reenginer out the solution porsche engineered in.
This is a short wheel base, high horsepower car with a tremendous amount of weight behind the rear wheels. By removing the all wheel drive you've created more rear weight bais. NOT GOOD unless you run much bigger rear tires and a huge wing.
Remember those 993 GT2s' were built for homologation purposes by porsche not as a superior handling car. Jeff Zwart ( who is really a talented driver) holds many Pikes Peak records was 16 seconds faster in a 993 tt over a two wheel drive 996 GT2 which he described as scary. If the sanctioning bodies allowed awd, you'd see more cars. I believe Audi won the Speed TV series with the awd and who could ever forget Hans Stuck destroying SCCA with an awd underpowered car against tube frame race cars then SCCA banned the car.
I believe crisp handling disaappears at about .85 Gs and then you want grip and the way to get it is awd.
