The trembling speed range might change, but anyway its trembling occurs again.

What year type/trim do you have on your Z ??

turning rotors are a quick fix that is more of a bandaid especially on a sports car.

i had the same issue with a rumbling/vibrating in the steeringwheel during braking at a specific speed point. over the speed was fine, under fine but only between 40 to 65.

i changed my rotors + pads last year and everything is good again.

i have a 2012 touring sport.

Your best bet is going to be to start over with some new rotors, new pads, proper bedding, and practice good braking habits going forward

A few tips on proper braking habits:
( Click to show/hide )
Come on the brake smooth and firm as needed and disengage similarly smooth. Emergency braking and riding the brake can both heat up the brake system significantly. Pay close attention when the brakes are hot and do what you can to avoid applying the brakes while stopped. When the rotors and pads are really hot and the brakes are applied while stopped, excess pad material is deposited on the rotor in a single spot. This creates a high point on the rotors and is often the culprit for your vibrating or shuddering under braking which is commonly though incorrectly referred to as "warped rotors". The worse it is the more you will notice it and at slower speeds.


oh and another thing, don't go through deep puddles if you can avoid them... i think thats why i warped mine. making wakes with hot/warm rotors touching cold water and rapid cooling.

and the holding the brake pedal down too hard during summer on my dd home from work
