Are these any good? I want to replace my rotors and these are $20 cheaper than the genuine Saab rotors.

 

[Kermit]

Never heard of 'em.

 

[Chapel976]

Never heard of 'em.

Every Zimmerman rotor I've ever used or installed is equal to or better than OEM spec. I use Brembo OEMs on my BMW, but used Zimmermans on my old VW.

I trust three rotor manufacturers for OEM Replacement: Brembo, Zimmerman and Ate. Zimmerman is generally OEM Replacement for most european cars... you don't normally hear the Zimmerman name because it generally just get's labelled as 'OEM'. It does at BMW. When we replace standard rotors here, they either come in Ate or Zimmerman labels in big white BMW boxes.
If you want upgrades, consider Ate Powerslots or Powerdisks. Does EBC make their Dot drilled and slotted rotors for 9-5s? They make a good rotor too... not a great big fan of their pads though. I run EBC reds on my e30 and they have less than good initial bite but powerful warm bite. Might work better in a heavier car like a 9-5. The greens might not be enough for a 9-5

I'm not looking for anything fancy, drilled and slotted rotors are a hassle I don't wanna deal with. Plus it's extra $$$ and to be honest the car stops more than fast enough as it is. The extra stopping power is gonna come from the PBR Metal Master pads I'm putting on. :cheesy:

The slotted rotors do help expel some of the heat put forth by good pads. It also helps scrape off the pad when it starts to get coked up too. I run regular rotors though... so...

My problem with slotted rotors are A) they cost more, and I beat up my brakes quite a bit and B) you can't cut them should they become warped. Besides, the ABS kicks in when I put the pedal to floor, and that's with the stock pads. No, plain jane OEM replacements and a good sport pad are all I really need. Besides, I've heard those drilled and slotted rotors can crack and break.

I am confused, a warped rotor is a sign of to much heat. The idea of grooved or drilled is to stop the warping.. No cracking with a grooved disk only a slight possibility with drilled, having said that I have never seen a drilled one crack in recent years. With a grooved disk and a fast road pad the abs doesnt kick in as quickly. I used a metal compound pad a few years back before the ceramics were available, they used to get so hot on the smooth disk that red hot iron fillings used to pit my alloys.

what are rotors? THe brake pads?
how much does it cost for the rotors? :cheesy:

I'm like a boy who wanders in half way through the conversation, i'm out of my element here.

They are what the pads chomp into when activated by the calipers (which contain/hold the pads).

Have a look:

Our mates at PFS call 'em discs..back in the day us Yanks did also but all of sudden they're rotors!

 

[Guest]

They are "Brake Disks" ......... You funny Americans :roll:

You know Finn, you have a good point there. Here's the deal though, I'm trying a new pad out, I have no idea what it's going to do to the disc. The stock pads chewed up the discs pretty bad, and I don't want to be putting down money for expensive discs if these do the same. Plus, they're still 12 inch discs, they'll still rip my face off if I want them to. :cheesy:

if you go with zimmermans or brembos, make sure you paint them before you install them on your car as they tend to rust very quickly. in my opinion nothing detracts more from a nice car than rusty rotors. paint can be bought at any autoparts store and is easy to apply when the rotors are new. the paint will wear off of the breaking surface and will protect all other areas from rust

painted calipers and viggen rotors

Hi metal content in a pad will often chew the rotors. If you need better stopping power then get a fast road pad such as Black diamond. If you need even better stopping power, ie you are getting brake fade. Then change the rotors to grooved, this will help the cooling and help brake fade and over heating to the rotors. Personally I will never go back to high metal content pads, for me ceramic is the only way to go.

I dont understand what you mean by "The stock pads chewed up the discs pretty bad". If you are saying that a saab pad chewed up your saab rotors then you were obviously asking far to much of them!!

 

[bobsaab]

Painted rotors? For real?

Calipers yes - but rotors?

I have cross-drills and yes they get rusty - but after the first brake hit the rust is gone.

And I suppose the non-painted area can get rusty also...

Anyone else paint their rotors?

 

[Chris 9-5]

Anyone else paint their rotors?

Obviously not the bit the pad touches! Here's mine:

 

[bobsaab]

Wow!

What type of paint is used? Hi-temp I imagine?

 

[Chris 9-5]

You can buy hi temp, hi cost caliper paint or much more reasonable engine lacquer, degrease and paint it on!

 

[bobsaab]

Hey - one pic has slots, the other doesn't. What's the deal?

Are you now running slots or flats?

 

[Chris 9-5]

Slots on front flats on rear
