AB,
I was considering both those tires for my boxster. Both got good reviews/test data. I ended up going with the Dunlops because I know the first version was very good and if the latest tire was better I would be happy. They have been good so far after 2 events giving me a #2 and #1 BRI placing. Carl Vanderschuit ran the Rivals so contact him (cvanders) on here for his thoughts.
Hope that helps.
