In comparing the 225 RS3's to 205 Dunlops,I liked the 205's better.Transitions were stupid precise,whereas the RS3's felt not really vague,but heavy.I have had both on a 15x8 wheel on a 96 B14.I'm all for wider is better,but personally I had more fun on the narrower tires.I taught at an autocross school last year,and ran over the flat spots of all 6 slalom cones with each of the 6 students.Sure made me look like I knew what I was doing.Still,can't wait to see how it all shakes out.
