I have the ES-100's on my 924S and they have not proven to be a limiting factor during the 10-12 DE's I've done with them. With these tires I can pretty much stay up with anyone in the turns...they are very predicatable and have higher grip than many that have commented abouve give them credit for...Now, if I could just get some more horsepower....

Not a bad tire, just not a track tire, I swapped ends without warning after 4 laps. The were like grease with the heat.
