Bill. If you think NT01 are good you will LOVE Hankook 221s - also called TD (you will have to hunt down a supply over there). Theres a detailed independant test using a 911 GT2 on the web which makes good reading (the test was in the States). The took the NT01 crown in the recent World Speed Time Attack comp....

Hi Bill. The Z214 is a good dry warm track tyre but its essentially a slick. The Z221 (TD) has groves and is driveable in wider conditions. I agree they arent easy to track down but I believe the popularity is increasing in the States so hopefully a reliable supplier will appear soon...

The MPSC had a tendency to loos the grip in a more dramatic way and hence I felt it more difficult to catch the car. They are also superior to the MPSC if there is a bit of water on the road where the Michelins where a nightmare!
I concur with your findings completely. One Speed Championship season I ran MSC tyres on my 993RSCS because there were no other options available to purchase. At that time I drove the car to and from events and duly got the shock of my life the first time I hit rain on the road - I ended up power sliding the car sideways for around 150m on a dual carriageway as I fought to regain control of the back end of the car after hitting shallow standing water. How on earth these tyres ever managed to get an E-mark to say they are road legal is completely beyond me. Dunlop D02G were much better but the R888 won my vote for best all rounder.
For my Speed Championship winning seasons I switched to Kuhmo Ecsta V700 V70A because they were available in a different compounds, my choice being medium for the hillclimb & sprint events I did. The V700 are another very good choice (and fairly competitively priced) but do require the car to be set up accurately and need a smooth driving style to get the best from them. For trackdays you would need the hard compound version.

I'm going to start tracking the 993 now (Colin fitted a LSD last year) and I'm just about finished on the suspension. I'm going to try the R888 following your feedback (and they are cheaper than the MPS which is a bonus if you get a better product)

This will probably be my last post on this build as this 9m93RSCS is due to leave Ninemeister tomorrow morning and destined be on its first trackday by the middle of next week.
The boys have been busy all week fine tuning the suspension at our local airfield and sorting out a few minor glitches which we expect on a complete car strip. Fate smiled on us and we were able to find a day to work on decoding the 88 pin ECU to eliminate the secondary air injection system and all its annoying engine check light malfunctions. The 993 turbo DAMOS file came in handy (index file for the main ecu chip) although it took Wayne and me a while to translate anything suspiscious from German to English. The good news is that my final 50 mile test drive this afternoon proved our mission successful at both eliminating the check lights and covering the car with road grime.....

.... resulting in me spending the rest of the afternoon pressure cleaning off the road grime, hand soaping and a good waxing of the bodywork, but at least now it's good to go.
We and the customer have learned a lot on our journey, a few highs and lows but only to be expected on such a comprehensive build. It's been a pleasure to photograph the build stage by stage and bring the photos to you all, I hope that you have enjoyed it as much as we all have?

Forgot to mention, it weighed in at a nudge over 1300kg with nearly a full tank of gas, take the fuel out and we are looking at a 100kg reduction from the original Carrera 4, probably about half attributable to the reduction in trim and half to the C4 to C2 conversion.

Car collected, ran the 700km trip home faultlessly apparently.
