Brake Package Specs
Does anyone have any further details on exactly who makes the various brake options for the F-Type? The official website and literature is annoyingly devoid of details. For example, I have the Super Performance Braking Package on my car - here's what the website has to say about it:
"The Super Performance brakes, featuring 380mm/376mm brake rotors, are fitted with red calipers for visual flair"
Does anyone know who makes this system? How many pistons in the front and rear calipers? Any further details?
Thanks!

According to that spreadsheet, they do - it also seems to indicate that the calipers are the same on all three options. If that was the case, what exactly would be the difference? The calipers are visually different on the three systems, so I think that spreadsheet is missing some info...

I'd be really surprised if they were any less than 4 - and for the rears, any less than 2. Especially with those large discs and a heavy car.

On the base, the larger super performance rotor/caliper should perform better than the standard base stock rotor/caliper by virtue of the larger diameter.
Looks like the difference between high performance and super performance lies in the larger rear rotors/calipers and not the fronts?

Does the number of pots make *that* much difference when the options are 2 or 4? Presumably braking force is the approx. the same, assuming master cylinders are the same?

Yes, larger disks should perform better than smaller, but 4 (or more) pots will provide more clamping power than 2. Holding disk size, vehicle weight, etc. constant, 4 pot calipers will produce shorter stopping distances than 2. You've doubled the number of hydraulic pistons, and the more piston area you have exposed to the fluid the more force is exerted onto the pad/disc.
Similarly, the fluid pressure in the brake system should be the same (assuming same master cylinder) no matter what calipers are on the ends of the lines - it doesn't increase because there are 4 pots rather than 2, but it IS spread more evenly over the back of the brake pad.
However, given that the brake pad backing is a relatively thick metal plate, I would opine that pressure distribution at the pad face would be essentially similar with 2 OR 4 pots or at least not vastly different with everything else remaining constant.
Regarldless of the pot count, you can get the super performance upgrade kit (as parts) for the base car for ~ $2700 consisting of 4 larger rotors, 4 calipers etc, which seems a fair price in the JLR universe - and possibly the only viable *available* upgrade for the base. Not so good a deal for the 'S' however as it already has larger front rotors and calipers.

The Super Performance front brakes are the same size as fitted to my XFR (380 mm) and they look identical from the outside (same caliper, same anti-rattle clip), so as my front brakes are definitely 2 pot I would guess the F-Type Super Performance front brakes are also 2 pot.

Not to labor the point BUT - a woman in high heels exerts more pressure per unit area compared to a woman in sneakers, HOWEVER, the total force exerted is the same in both cases b/c the force is due to the woman's weight, which is a constant.

The only consistent consensus I found was that "more pot" calipers are generally bigger and better at heat dissipation. That advantage would probably only be helpful in terms of keeping your brakes alive for longer race track sessions. They seem to make little or no difference in terms of stopping distances until brake fade begins to occur.
The same seems to be true of carbon fiber vs. conventional brakes. One review I found had the V6S w/ super performance brakes stopping from 60 in 106 ft. vs. 104 for the carbon fiber brakes.
I'd always accepted on faith that more pots were better, but after looking into it, that's not necessarily the case. The demand for them seems more driven by the "bling factor" than anything else.
