There was an interesting comment about the 964 RS being as fast as a 993 RS - can this be the case?
Yoda, taking Spa as a reference, the answer must be a clear 'no', especially if the comparison involves clubsport versions of the two models, and even with stock versions of the standard lightweight models. However, this wasn't always the case.
I have been an avid reader of the French Flat 6 magazine since its inception in '92. In French club racing, which I followed for several years, when the stock 993 RS came out, it was major disappointment against well-tuned 964 RSs... That is, the stock 993 RS was slower. But then, 964 RSs were comparatively easy and cheap to tune (e.g. hotfilms, 18 inch wheels). Some were really well tuned. With time and money 993 RSs caught up and became the tool of choice in club racing (especially when cup cars became available). It is only expected: stock 993 RSs already have more grip from larger wheels, bigger brakes, better ABS, better suspensions and stronger engines. Physics must prevail. However...
I know someone who drives at Spa quite a lot and quite well (Chfs911 knows him too as we spent 3 days at Spa with him). He owns a 964 Clubsport, a gorgeous 993 cup, a 996 cup and a 914 GT (and also a couple of 911s for the road). He raced in the 964 cup. His favourite car for Spa is not the fastest (which would be the 996 Cup, without a doubt), but the ... 964 Clubsport. For him, the issue is not overall speed (he is not racing anymore), but feel...
On this dimension of clarity of feedback from the steering wheel and seat of the pants, the 964 RS wins over the 993 RS. Is there anyone out there who disagrees with this statement? You must have driven the two models to be able to disagree [
