I am thinking to get new rotors all around - seems time to get them done as the pads have worn 5-6mm on each side.

I am not doing slotted or drilled - so the question is:

New OEM?
New Zimmerman?
New other aftermarket?

Any thoughts? I lean usually toward OEM, but I think here that since I am not going with drilled rotors, that quality may be as good or better for alot less money going aftermarket.

I just ordered zimmermans myself and will be putting them on this weekend. I've used them on my previous M coupe and M3's and never had a problem.

Sebro make the OE ones I believe.

Whatever you chose, spray extra sliver paint on the rotor hats before you install them to prevent rust showing up down the road.

I had a bad experience w/ Zimmerman, however, I must quantify this as I heavily abuse rotors in DE'ing. The rotors "spider cracked" in short order, actually to a point that I was concerned that they would shatter under hard braking.

LouZ- you are using Zimmerman Drilled rotors? Or undrilled....?

Makmov

I need rotors on my car. Have not decided what to go with yet.

Zimmerman crossdrilled on mine. No complaints so far.

Makmov

That is what I have been thing about using but some have said they are crap.

At some point in time after our cars were built Zimmerman was a Porsche factory supplier so they can't be all bad.

I found sebro for 90 dollars- uhmmmmm....I think Sebro for 90 vs OEM for 350 might win...

I found Zimmermans rusted and cracked quickly.

I have DBA on the rear and find them great (grooved, not drilled) and Wilwood on the front but those are are over-kill for a street car so DBA on the front would be my choice.

I WAS using undrilled Zimmerman's!

Now I use a slotted rotor that is cryogenically frozen and it's holding up!

If you have some piece of supporting documentation or even just source for this, please post it. Unless something has changed in the last 3-4 years (which I doubt) this is not the case. I do realize that Porsche is now multiple-sourcing parts but I also question the Sebro as an OE rotor supplier to PAG. They might have been used in a few special "classic" restoration cases. And yes, it does make a difference!

Makmov

I will try to find it again.

All I know is they were officially listed as a OE supplier to Porsche. However, for what years, what cars, and what they supplied is not clear.

And I didn't suggest that was Zimmerman who was the OE supplier on our cars, I said sometime after our cars were built Zimmerman supplied parts for other Porsches.

And, yes, it is unclear if Sebro was even the OE supplier for 964 brake rotors.

Goughary

Well - also - keep in mind that OE Supplier doesnt mean they make their parts the same way as Porsche (or any other client) would specify. All it means is that One company went to them and used their facilities to product a product with their name.

I still think i am going Sebro just due to price. I'll be on a track maybe a few times, maybe once. So for street use - Cheeper the better for a rotor. I'll give them a quick shot of paint and throw them on. if they get bad, they are still three times cheeper than OEM.
