Kempo

I need to replace the discs and pads on my 2010 WRXS. It has the 295mm diameter discs so wondering what people recommend as alternative to OE parts. I've found the braking performance to be fine for my use so the things I want are:

Style - I like the look of grooved / dimpled discs etc as long as they are not noisy and don't warp

Finish - the stock discs appear to be treated on the hub part as they have not rusted and are a pale black colour

Cost - want to do it all for under £250

All thoughts and help appreciated. Where is best place to source OE parts if that is the choice.
