That's how you're driving it, not an innate characteristic of the car.
If you can't drive it that quickly while also keeping an eye out for
what's going on around you, then you're driving too fast for your
abilities.
Oh dear! It is precisely because one is aware of what other motorists
are doing that one sometimes has to pull quite a lot of speed off in a
hurry. You haven't been in this newsgroup for very long so I accept
that you don't know much about me. Quick summary - driving for 40
years, clean licence, no accidents, high-speed trained for the road by
a mix of police class one and former GP drivers, driven everythying
from Morris Minors to Ferraris, writing about motoring for years, etc.
Apologies if my comment might have sounded a bit glib, but I do know
what I am talking about.
High performance cars like the Rex, when driven to their potential
(however well and safely) will get through brake pads pretty quickly.
If you are using up pads, you are also using up the discs. This is
true of all modern cars, where the discs are regarded as sacrificial.
It is not unusual to have to change the front discs on a high
performance car every 20 or 30 thousand miles.
