Cheers Adrian, I'm already running the Hawk ceramic pads, braided hoses and Motul fluid but the StopTech discs are an option
In that case, keep the pads for now and just change the brake discs, take the car on the track, see how it performs and take it from there.
I use Pagid RS29 on the GT-R, they are just brilliant, but very aggressive for the discs and they squeal.
