Yepez, can only write in English, maybe Alvaro can help translating.
I would definitely recommend the yellow stuff for the GTV6 as I have used it for racing, where it was very effective. So presently we are using it on most of our cars for road also! Well we love this compund!
Have used Green stuff before, but it was nothing special with that, just that it did not make as much dust on the wheels as the original ones. Braking performance is definitely inferior to the yellow stuff.
Have not used the Red stuff, so I cant say, but its for racing, and needs time to heat up to work properly. Unsuitable for road use. Have not used in racing as we need good brakes even when the brakes are cold or its raining!
