Im using EBC disks and OEM pads at the minute, done a track day on them and they felt superb
Just as **** You wont gain a thing from using them....
In all honesty with a 1.4 underneath you, OEM brakes will more than be up to to the job...you wont be that hard on the stoppers at the Ring because you wont be pulling silly speeds anywhere & especially with it being your first time....trust me
Best off using the money you save on aftermarket pads/discs to give your calipers a good clean & change the brake fluid to castrol response & fit some nice OEM discs/pads
Job done!
