I have noticed what I think is an interesting trend in autox this year. The MR2 Spyder is doing very very well in ES and it seems that all the top placing drivers are riding on BF Goodrich Rival 1.5 tires. Meanwhile, the MX-5 which is the Spyders competition in ES is using the Bridgestone RE71-r almost exclusively. That trend is repeated for all the other classes where the MX-5 is one of the dominant chassis. CS and STR MX-5 drivers also almost all use the RE71-r.
I would like to hear from some of the ES drivers on what traits in particular make the Rival the superior tire when paired with the MR2 Spyder and its McPhearson strut chassis. I have read many reviews and in most of them the RE71-r appears to be the superior tire. However, the dominance of the Rival shod Spyders is ES so far this year cannot be denied and seems to contradict this view, at least in the case of the MR2 Spyder.
If any of you ES drivers would share your thoughts, I would appreciate the insight.
