Wilwood 6-piston vs 4-piston

[Zach34]

After some searching, I'm not sure anybody is actually running the large 6-piston/4-piston Wilwood option on an 818 R or S yet.

The FFR red car pictures show the 4-piston.

I had 13", 6-piston fronts on my Roadster for some autox and two track days and I loved them. They were easy to modulate with an aftermarket manual master cylinder, and they had no problem at Auto Club Speedway.

My priorities here are:

1. reliability
2. durability
3. performance
4. weight

I'm perfectly fine accepting the additional weight of the 6-piston fronts as long as there is a tangible benefit in durability and performance. So my question is: Is there a tangible benefit in durability and/or braking performance with the big 6-piston kit over the 4-piston kit?

The pursuit of weight savings often involves compromises that amateurs like me can't afford in the long run. I think by the time the R is put on the scales it will only be a couple hundred pounds lighter than the Roadsters, so I'm leaning toward the 6-piston since I liked them so much on my Roadster.
