I have had these Super Sports on for one fall and a full summer now. They are mounted on my Highly modified C4 (Stage3 kompressor, JCI magic racing struts, HR Sway bars) I had SO3's and RE960's (winter) on it in the past. These are the BEST yet. Last Year, I just got them broken in in time to take off for season, so starting spring 12' I turned them loose in the mountians in N.E. TN. Nearly 500 hp and these things are TOTALLY glued to the roadway.
The ride is better then SO3's and the wear seems better. The So3's were only slightly better about Hydorplaneing (the only reason for the only 9 I gave the S.S.'s. For those of you familar with the mountians in N.E. TN and NC the curves rival even the Euro tracks, and these tires are as advertised and better. I'm looking forward to trying them @ VIR, Barber and Sebring D.E.'s I suspect I'll be hunting Zo6 and 458.
