I've had 2 sets of RE-11s in stock zcp sizes and will continue to run them
for street/track dual duty (until I get a dedicated R-comp set for the track).
The grip is so good that I don't feel the need for bigger tires (they run wide
with square shoulder) and I really like the stiffer sidewall feeling. My current
set is wearing much more evenly after I installed camber plates. so far I've
had 6 track days and 10k miles and should be able to get another track wknd
plus few more months out of them.
