Brake discs Zimmermann or OEM Volkswagen

Zimmermann rotors are good and the price is good also .

I had the impression that those discs wouldn’t warp as easy as one piece discs but it looks as I was wrong. VW tried to machine my warped discs with them mounted on the car at one point but they failed so badly that they did not even want to show me the result. After that they messured the runout on new discs on the bench and found them OK. After the discs were mounted on the hubs they were messured again and that one of them had warped. That was the way they found the bad hub. I was quite surprised when I was told that VW did not have any tolerances for the runout on the hubs or the discs. I took for granted that they had quite strict tolerances both on the hubs and the discs. I don’t know if the eight piston caliper and the setup with opposed pistons makes the whole system more sensitive to warpage or not but that has been suggested. And to get this a bit more connected to the thread subject I can add that I have not found any alternative to VW original 365 mm floating discs at all. I was quite surprised to find them cheaper than the one piece 334 mm discs to my Passat W8 though.

Could be the hubs. Mine had an axial throw of 0,02-0,03 mm which I thought wouldn’t affect the discs. I filed a complainment to VW regarding warped discs and they blamed the calipers. Told me one of eight pistons was a bit sluggish. With new calipers and two sets of discs later they found what I had meassured before the complainment, a warped hub. The last pair have not warped after the typical 5000 km mark as before. So at least the floating 365 mm discs are very sensitive regarding straight hubs.

I recently did my rear brakes; all new pads and rotors. I stuck with Oem brand parts; Zimmerman rotors (made in Germany), which were the same brand as the stock ones I took off, looked identical and stock VW pads TRW (Made in USA). Performance wise; I am sure, other pads probably would perform better with lower dust, etc. Mine lasted 16 years and I figured they worked ok, lasting a very long time and I knew the type of performance they were.

Anyway 09 Tig SE and went with Zimmerman Rotors and brembo pads. Alls I have to say is a good choice. Not low end - not super deluxe - assume all Made in Europe. happy with the quality of hwy braking and that’s all that matters for me.

I went with Zimmerman z-coat rotors and Hawks Performance Ceramic pads when I had my E46. Great stopping power, and low brake dust. The bite was progressive, so it required a little more force on the brake pedal, but it was easy to modulate how much you wanted to brake.

Have them on my Tiguan with Zimmerman rotors, not a peep so far, excellent grip too.

I went with Zimmerman Rotors and EBC Red Stuff pads from NGP. Not slotted or drilled, just a quality German made rotor. The material quality difference is evident. My only complaint is the Red Stuff pads do make more brake dust, but its a pretty minor grievance. The rotors were also coated to prevent unsightly rusting.

It was brought in by another shop that installed rear brake pads and rotors.

front brakes already instaled also i changed brakes fluid for little better one ATE Blue Racing and now it stops better after a while i figure out there is some problems with brakes... i tried to find what is wrong... finally i got it!! brakes callipers was broken... pistons where jammed in callipers... i send it back.. i got cashback and i order another set from diffrent seler unfortunatelly i need to buy another set of brake discs... drilled zimermann set.
