993 C2 vs C4 on the Track

I'm curious about the performance trade-off between 4WD/2WD and the handling characteristics and respective 3175/3065 curb weights of these 993 variants.

Assuming both 993's are stock except for track-friendly suspension and big reds, which would result in lower lap times for (1) someone with intermediate D/E experience or (2) someone with extensive experience, such as Ruf's own test driver (I am reminded of the Yellow Bird video)?

I guess what I'm wondering is, do the benefits from the 993 4WD more than make up for its different handling characteristics (I'm assuming the 4WD does not allow the driver to "throw" the car around as much) and the additional 110 lbs?

Would increasing torque/horsepower (e.g., Protomotive turbocharger) result in a different conclusion?

Thanks.

Based on my observations, the 993 does not have enough power to be traction-limited on a race track with two wheeldrive. The lighter car with less drivetrain inertia should be faster; however, the Audi Quattro Trans Am cars of the late 1980s show the merits of four wheel drive in high-horsepower relatively heavy race cars. Slick tracks strongly favor four wheel drive.

My understanding of this is that the C4 in standard form exbits greater under stear on the track.

Actually I've read this more in conjunction with the 964 than the 993.
However it can be ironed out, I think more negative camber helps.

I'd check rennlist for 993 related stuff. It's been discussed in length over there.

I reckon though AWD doesnt help on the track. Otherwise we would see a lot more track cars with it.
I've no personal experience with AWD on the track though, or for that matter on the road.
My simple understanding is that AWD would impove control once traction is lost, but it wont give you more traction.
Hence it's essential for rallye and off roading.

Porsche's GT3 is only 2WD and the forth coming Carreara GT is also. But the 959 was AWD, but that has rally roots to an extent.

But I could be totally wrong about it all.
(Life and AWD) hehe
