If someone is consistently activating ABS with them that means they are lead-footin', crazy steppin' f00ls

In other words, they're too hard on the brakes.
The Ultimates are a good pad. They will squeak a bit and they dust a lot more than an OEM type pad but that is to be expected from a ceramic pad. The important thing to do is to bed them in properly. They should come with instructions but normally you do approx. 10 sessions of braking, first from 40mph-5, then a couple from 60-5. Don't come to a complete stop. The pads should be sizzling by the end of it and smelling good and you should now have a grey layer on the rotor. Then let them cool.
