What discs do you have to put on these kits?

Do I have to put them on from Scoobysport or can I source elsewhere?

I want the 330mm or the 372mm.

Currently using 330mm. Will I have to change anything to goto 372mm?

This page (http://www.kad-uk.com/subaru_brake_upgrades.htm) suggests that 330mm and 372mm use different caliper types. Suggest asking KAD directly, then SS if necessary.

Thanks!

We use exactly the same disc from KAD
