Ok, i wish i never bought the firehawk indy 500.
Maybe it's the best for the money but in comparison with the Michelin Pilot sport 4S are night and day.
Except the they're more narrow and there is no much protection for the wheel,
where do i start... much quieter - comfortable - the steering wheel more stable on higher speeds (due to this amazing sidewall). Big mistake that i went with the INDY 500 in the first place.
I didn't expect that much of a difference but WOW.
In a few words, for 250-300$ more buy the 4S - THANK ME LATER
