Front brakes judder

[aleks_lvr]

Hey everyone!

Just replaced the front brake pads with Hawk DTC-60 and the rotors with Zimmermann Coat Z (single-piece). After a few track sessions with braking from 140 mph, I’m getting some judder that goes away once things cool down. I suspect the rotors can’t handle the heat. Any advice on whether I should try the Zimmermann Formula F (two-piece) or just go straight for Girodisc?

I use the cheapest 1 piece rotors available and they handle DTC60's braking from 149mph lap after lap after lap.

You didn't bed them in well enough.
