Stock pads are actually not that bad on track.
The biggest issue most people have with them is that they don't have that much 'bite' in them (esp. with rain when water gets onto the discs and pads)
Perhaps this issue will be less on the Fed-Elise and the 111R as they have brake boosters, unlike the older Elises which are non-assisted.
Brake fade and such are not very common on the Elise to start with, as the low weight of the car and the relatively big brake rotors means that brake temperatures remain within acceptable limits.
Even the motorsport elises didn't run with brake-ducts, because when they tried it actually over-cooled the brakes, which you really don't want if you run full-on race pads that really need some heat in the system to start working properly
Bedding in is still needed on new cars. The initial running-in period is great to also slowly let the pads get a good contact with the rotors.
Once that's done do about 3 to 4 medium brake actions from around 60mph to 20mph (do not come to a stop!). Make sure there's not more than 30 seconds or so between each brake application.
This gets everything up to temperature. Now do another 4 *hard* (very close to lock-up/ABS activation) brake applications from around 70/80 mph to 10 mph (again.. do *not* come to a complete stop) to fully bed in the brakes and heat-cycle the pads.
Then drive the car gently and let the brakes cool down. Do not apply the hand-brake or keep your foot on the brakes at a traffic light during this time.
Repeating this process once in a while also 'refreshes' the pads (burns off any deposits and breaks glazing) and helps to keep the car brake properly.
The brakes on these cars are meant to be (ab)'used' hard and if they are not put through their paces regularly they don't work as well.
