Did you have ceramics on your last GT3? If not, did you miss anything? There is your answer. For me personally they are a must and worth every penny.

I value your opinion. Why are they a must?Smiley

To answer your question, I can't say I missed anything on the GT3 but I didn't have anything to compare it to. I always thought standard Porsche brakes were excellent. 

IN short it is brake feel and precision of braking . The reduction in weight and lack of brake dust are bonuses too.
