Godspeed.....Non-floating.
TBH, PF's are not gonna make it worst, and sometimes we all do stuff to our cars because we just want to spend the money on 'the best' that we can afford and without any logic or application of science. E.g. The Cup spoiler isn't gonna really help with downforce.
Equally people forget even if you buy the latest Nike's, still wont make you play any better or turn you into Ronaldo....Therefore, so not sure about Bigger Brakes helping with laps times (£), I guessing track day lessons are better (£) spent in that instance.
If my brakes were snagged, and I had the money, PF's for me (without the rattles)
