My rear rotors are now 24 years old and looking the worse for wear though still above the minimum thickness spec.
I use the car for regular track days with regular stopping from 100 mph.
A simple upgrade without going to larger rotors is to replace with 'better' one:
Choices - slotted rotors R slot and S Type
- dimpled and slotted
- J slotted

I have been advised that with the 10 mm thick rear rotor the slotted one may crack when hot.
This is not just about outright lap times but also making sure it doesn't end up in the sand trap
after back to back runs when numbers dwindle. When I decide I will be doing front and rear.
