i am using the street version of the millways. one track day on them so far and i think they are doing pretty great. can't say much about them on the street as i don't drive the car much outside of track at this point lol. but honestly to me it does not feel much, if any, different from the stock setup. granted i only drove the stock setup to 1150mi, did break-in, then went to 1 track day and that is all the driving i've done really. another track day at the end of july. see how they hold up then
