Performance brake pads recommendation

Hi all, has any one replaced the oem brake pads with aftermarket branded pads? Would like to know the options available for i8.

In addition, some online retailers are saying that i8 shares the same stock brake caliper with M2/M3/M4, therefore, all of the M car sized brake pads can fit into i8 as well. Can anyone confirm this? thanks!

Garage List
I found that repeated hard braking from high speed at a track day was not what I wanted. After a frustrating search I ended up with EBC Yellow and am quite happy. Solid stopping power and minimal fade. First few stops cold are reduced response but quickly come to operating range. Many manufacturers offer front pads but then not rear. I wasn't willing to mix brands so EBC. Having said that, I took my old rear pads down to my favourite shop and started opening boxes. There are lots of identical pads. They are not listed because the i8 apparently specs the rear pads at 1 mm less thickness. Knowing this I would simply buy whatever your favourite brand and buy the M3 rear pad and "adjust" if necessary.

I've read on a forum where someone has obtained Porterfield AP1609 and AP1473 pads for the front and rear, but hasn't installed them yet. I'm curious if these would actually work OK before attempting.
I daily drive my BMW i8 and enjoy doing my own service. If you're interested, please follow along on my journey to maintain and improve my i8.
