Found out that race brakes are going to be putting a kit together which includes a 355mm rotor and 2 pot caliper.

No details out yet other than the size of the rotor, no idea even which caliper will be used. The idea is that it will fill a hole in the market for people who want a bigger rotor but can't afford 4 pots.

I like the idea of it but they are working off an 18 inch rim template so it may not fit 17s. I wouldn't think there be any performance increase over the Premiums with 325mm disks but it will look nice.

You thought wrong, larger diameter discs offer a higher torque value for you brake system while allowing you to more easily modulate your braking force

Sounds good any idea on price?

Only 2 pot.

Sounds like they'll be cheap compared to other kits that size and hope that the buyer just focuses on the 355mm part.
