I can see why this is confusing.
If you prefer to buy the
front from ECS, here is the link

But if you want to save money. You can buy the parts yourself and save thousands. I'm offering any helps and advices for those who needed, afterall, that's what this forum is about.
Don't even think about asking ECS to part out their kit, THEY WILL NOT. That's one of the reason why I wanted to do this in the first place.
The rear brake is a different story.
If you upgraded your front into 6 pots Cayenne w/ 350mm. Your car will have serious braking bias problem. The front will now do 90% of the braking while the rear just lugging along. This is dangerous, on or off track. Most people upgrade their rear into R32 312mm rotors but that still is inadequate pairing to the 6 pots front. So I designed the rear Cayenne brake myself. The first ever.
My day job, I'm a state licensed ME engineer specialized in heavy machinery/custom military equipments. I've been designing brake upgrades as a hobby since college days for our school competition track cars and numerous cars I owned. I have the design skills, access to machine shops, know where to get the quality parts cheap. So it's ridiculous for me to pay $5500 for a rear brake kit from Europe w/ a two months waiting list. When I first did this, I did it all alone w/ no helps but that what i do and I loved it. So yeah, this isn't exactly complete kit that you just buy, but if you shop all the parts yourself and get my bracket, you get yourself one hell of a brake system that turns every heads on the road.
I helped guys in Canada, UK, Norway, Turkey, Japan and Australia did this and they absolutely loved it. It's a one of a kind system and you will stand out.
