any opinions on Zimmerman rotors vs. orginal equipment?
Any problems with zimmerman? Any real benefits to original.
Only hard street driving, no track.
I thought Zimmerman was also the manufacturer for the OEM rotors. I put a set of new rotors on the front of the blue 83 right after I bought it 2 years ago. Due to availablity, one side was OEM, the other was a Zimmerman. I had to add some flat gray paint to the zimmerman so it looked the same. Looked identical with paint. 2 years later. Still very nice. Used it at the track for 2 DE's with street pads. No problems. No warping to date. Rock solid.
Thank you, nice to hear as I had to order them already. (only ones I could
get before next week as this weekend is 'brake job' weekend.)
The other option was Porsche original, not "OEM". From what I
OEM means that they will fit and work, but aren't necessarily exactly the
same quality standards as "original" parts.
My understanding is that OEM stands for Original Equipment Manufacturer.
Meaning that they manufacture rotors FOR Porsche.
The only real difference that I am aware of is that the "Porsche" rotors have the "hats" painted, and the Zims will not. Best to give them a shot(the hat not the rotor surface) before installation otherwise they will get rusty quick. Rather ugly when running an open style wheel.
Well, whatever OEM means. One came in a box with Porsche written all over it, and the other one came in a box with Zimmerman written on it. Only difference I could tell was the paint. Braking and wear seems even between the sides.
Ive had great luck with zimmerman. especially, ones for the S4.(they come drilled standard)
great stuff, even for the track!!
I have used Zimmerman without trouble on my OB and my 20v quattro. Both with no problems.
IF you drive hard (street, or especially DE's at a track), the typical
"grey" paint may not hold up very well. I've had good success with
thoroughly cleaning the hats of Zimmerman (et.al) rotors with Paint thinner,
followed by Lacquer thinner, letting dry briefly, then spraying two or three
thin coats of BBQ grille black on them. This paint is supposedly stable up
to temps of ~1200-1300 degrees F, and does protect the rotors hats from rusting.
