GT2/3 rear pads when converting to steel discs

[NBTBRV8]

Guys,

When you convert from PCCB to steel rotors what pads are you putting in the rear, are they the same as the normal GT3/turbo steel pad or are they a larger pad due to the 350mm rotor?

Also I am looking for a new or excellent condition red (steel) right hand front 6 piston caliper, so if anybody has one for sale please PM me.

Thanks
