Uprated discs for track & sprint
 

I plan on keeping the std Brembo set up for track and sls next season so ideally I'm looking at replacing the std discs with discs that's will last and so the job better, any recommendations?

I sprinted my Wagon with Godspeed big discs & standard callipers & large Blue Stuff pads. A VG combo.

326mm discs? 2pc? Is that the ones @ £300?

No, it was this one:
