I have them on my FR-S in 205/45-17 and prefer them over the Continental's (which I also had in 205/45-17)... best daily driver tire I've ever had, equally great handling in the wet and the dry with a little better ride quality than the Continentals. Just the right level of stick for the FR-S on the street, my top reccomendation for street tire for the FR-S and highly reccomend trying 205/45-17 sized tires on 17x7.5 wheels with +40mm offset for the FR-S. For track I'd probably run 215/45-17 DOT-R compound tires, like the Nitto NT-01, on 17x8 wheels... like the NT-01 when I ran it on the Integra RS I use to have.
