OK.. Here's the dilemma.. I can get the Stoptech brake setup for $1695 (front kit) the system comes with rotors, calipers, pads, steel brake lines and Motul Brake fluid..

Now I can get the AP Racing setup for $1675(front kit) the system comes with rotors, calipers and pads, (no steel lines and brake fluid). PS Ap is coming out with a two-piston caliper to fit the stock rear rotors...

Both setups are 13.1 inch rotors, 4-piston calipers...

?'s

1. Whats the benefit of a two-piece rotor and a one piece rotor??

2. Which setup is better ??? (AP Racing or Stoptech)

3. What would you get??

 

Check what the rotor material is made of.

 

I'd go with the Stoptech kit. They have done extensive testing with the Z, and tailored their kit to work with the stock system. Also, they have superb customer support. You can call the people who actually make the brakes, and get answers right from the source. I think that is a huge advantage if you ever have any questions or run into problems. I wouldn't think twice...I'd go with Stoptech.
