It is amazing how the whole system needs to work together. For example I ran the Conti scrubs with the above stock suspension -2.2 front……..I was faster once I got the tires greasy and car started to move around. Thus the tire was not over powering the suspension.
I've run the R888's on a Spec Miata as the above poster noted. The R888 is not a great tire unless it's perfectly dialed. It is slower than the RA1 unless you have the setup (temps, camber) perfect, and even then there are better R-compounds to try with easier setup parameters ie RA1, NT01, BFG R1, Hoosier R (aka Conti Extreme Contact Race scrubs).
