Typically the rotor itself is stamped with a minimum thickness spec. Do yours have such stampings? If so, that's what I would go with.

EBC gold anodized rotors are $300 each. Did you find some cheaper?
Brembo's from Coventry West are $37 each.

1978 Jaguar XJS ,fronts!
i dont know about Genuine Brembos for $37. each.
heck , just throw a set of pads on it,forget the resurfacing, save money!

I'm with that.
Rotors only need turning if they have an issue. Usually,
not, unless the pads were run down to the metal. and, then the gauges might be so bad as to make turning useless.
Scuff off any glaze if one wishes, make one feel useful. Actually,
not really, it will be right back on a bit of use.
Swapped out the pads on the front of my XJ wuzza six a few years ago. A bit prematurely. But, better than too late!!! Rotors decent, left them in. Braked just fine.
A bit later, oh, oh, losing fluid. drops under the rear!!! Yup, back calipers oozing...
Farmed out that job. Loaded rebuilt calipers via Rock Auto. Rotors good, still there. braking better, yet....
Way back when, my IHC Scout II and 85 Ford F150 used the same braking system. Each ate one pad per side and grooved the rotors.
I lived with it for a while. I could knock in fresh set of pads quickly.
But, then broke down and refreshed them, rotors, calipers and pads.
No discernible difference in braking????

Replacing pads,rotors, calipers, etc is probably never going to be noticeable in normal traffic, except some warped rotors. The rest of the increased performance is picked up under hard braking and continued use, where less fade is apparent. So unless you slam the brakes enough to remember the difference, you aren't aware by the seat of the pants the smaller stopping distance from speed. Although I am personally a fan of brake checks to make myself aware of my own stopping distance. Nothing like hitting the floor once in a blue moon, only to find you keep going much further than expected!
I would also expect both of those vehicles to have garbage braking performance anyway, so even "up to spec" still means sub-optimal.

Most people with a new-to-them XJS probably have somewhat out of shape rotors that don't feel to noticeable, but given their age provide a little bit of oscillation under braking.
