I had Kumho Ecsta SPT's on my Honda S2000 and they were my second favorite tire during the 70,000 miles I owned it. I also had Bridgestone Potenza S02's (the factory tire and my favorite, but they lasted about 5-8K miles in the rear), Sumitomo HTRZ II's, Yokohama AVS Sport's and Toyo Proxes T1-S's.
An S2000 is not a Crossfire, but it is a short wheelbase, rear wheel drive vehicle, with staggered width front and rear tires, of no too dissimilar weight when compared with one. I will probably give The Ecsta SPT's a try on my SRT6 when it is time (and that won't be too long).
