I have Bridgestones on still and have been pretty happy with them, I find them predictable and quiet and the grip was ok when they were new ,rears are getting a little low now and are struggling to put the power down a little, I’ve been very impressed by vredesteins had them on my old 535 and just had them fitted on my wife’s Impreza wrx , and my son has them on his vrs , good grip and in the rain , always seem to be near the top on tyre reviews, don’t know if they come in isf sizes?
