Firstly, you must have done something wrong to warp disks in a month - cooled too fast etc, whatever disks you buy will do this.
I need some new discs soon (Got HC's now) and am thinking about going OE / aftermarket standard replacement or Max. This is a quote from the Brembo website:
"Brembo high carbon cast iron rotors better dampen vibration and noise to improve comfort and, ultimately, performance."
It does not mention improved braking / heat tolerance etc, are they really worth the extra money?
The grooved 'max' discs on the other hand are advertised by Brembo as being their 'performance' disc:

[FONT=tahoma,arial,helvetica,sans-serif]Obviously its all advertising at the end of the day and I'm not really sure you'll notice much differance in the Clio but i'd be inclined to either go OE for cheapness or Max if you can afford them.[/FONT]
