I am looking to upgrade the front brake rotors on an 87 944 turbo, non M030 suspension. Do I have any other selections other than Sebro or Zimmerman?

I am trying to find a more durable rotor, I am developing zillions of small cracks. I have ducting to the fronts, so I do not think lack of air flow is the issue...but again, open to suggestions.

Thanks in advance.

I'm on Zimmermans all roun now and they are holding up well. I've been told the OE Porsche ones are the best though.

I have had the best luck with solid OEM. I even tried the Frozen Rotor variant with not much difference. Small cracks are expected with a car that is tracked. I do have a set of of Sebro on the car now only because I got a deal. Two sets for the price of one set of OEM. We'll see how they hold up.

I run OEM rotors that I buy from Sunset. Make you have enough cooling, pick pads that aren't overly hard on rotors and learn to brake less. It is the last part that has made the most difference for me!

Get used to the idea that rotors are a consumable on a track car, like oil and gas....

The fine stress cracks on the surface are normal and can see them even after a single hard use. Keep an eye on it and run them until the cracks propagate nearly all the way thru.

+1 to the above comments - OE last longer than aftermarket zimmerman. Buy from one of the discount dealerships, Sunset (westcoast) or Hennessey (east coast), at 25-30% off list price they are not significantly more expensive than the aftermarket rotors.

Check out Stop Tech to see if they have a two piece rotor. Initial would be high but they do last and then you only replace the rotor not the hat. Giro Disc may have a disc also and their quality is pretty high.
