Nick ebc green will be fine, you need to be very much the seasoned track day warrior or a racer to bother with anything more extreme that needs a lot of heat, if you typically do half a dozen flying laps followed by a cool down lap. At our level of track experience in relativly slow reasonably light cars, crazy brakes is overkill, and more extreme pads are not ideal for road use and getting to and from the track either of course. I have Also heard that the pagid fr pads are also very good....
If you do go for the ebc pads, don't fit the anti vibration packing or whatever it's called behind the pad, as I'm told this can cause the pad to wiggle about!
