6 pots would be a complete waste of money on a festa, some decent 4 pots are more than enough, combine these with some decent yellowstuff pads, and grooved/dimpled/drilled discs and braided lines with DOT 4 fluid.
DON'T use dot 5 or 5.1.
The festa simply doesn't weigh enough to need 6 pots, even std cast cossie 2wd 4 pots would be way more than up to the job.
