The S20s are actually **** good tires. I've been through the OEM set on my 636 and moved to the Dunlop Q3. It was a great tire as well. But not very neutral. The current set on my 636 is the S20 Evo. I've got 4 intermediate group track days on them and maybe 1000 street miles and they are hosing up great and have dealt with everything I've asked from them, including predictable spins and slides.
I have around 2700 miles on the OEM S20s on my 14 N1K and they are just about 50% through their lifespan. I have a set of S20 Evos waiting to go on before I hit Deals Gap next month. I opted for the 55 rear this time.
