Floating disc or fixed 2 part disc for track

[kaveney]

Hi all

Im just looking for some information on what would be best .

I will be looking to run an AP racing 4 pot front brake set up with Pagid RS29 pads on my Fiesta ST MK7 but am not sure if a floating to part disc or a fixed two part disc will be best .

The car will be only driven on the roads to track day events so will be 90 % track car only with 10 % road use .

Is the extra cost and noise worth it for the floating disc option .

Thanks
