Brake discs Zimmermann or STOPTECH

I put about 4k miles on the Zimmerman front rotors + Hawks HPS 5.0 so far. There is still a little squealing coming from the setup. Very small. Pretty sure the pads are the reason. Not the rotors. Lots of people are using thre Zimm rotors here in Quebec Canada. And noise isssue isn't something that comes in the reviews.

Rotors are good. Least amount of balancing machining marks I’ve seen on single piece aftermarket rotors.

Zimmerman rotors, will not warp or crack like inferior chinese metals.

I am about to get pads and rotors done all around at 110,000km. Textar pads and Zimmerman rotors

+1 for Zimmerman rotors. They are great and resist against rust better than the oem discs. I’m currently on HPS5.0 and Zimmerman at front. Braking power is great. No dust almost.

I just installed Zimmerman rotors with the stoptech pads upfront and ate ceramic pads for the rear. Performance has been excellent for a street driven car. Noticeably better than the stock pads.

I used Tire Rack for Stoptech rotors. Not sure if it’s really a bonus but I sprung for the cryo-sportstop. They look great and are smooth. I wouldn’t look at Stillen rotors. They were unbalanced garbage.

Swapped them out for Stoptech drilled/slotted rotors and the problem was better.

I'm going to need front brakes soon. Last time I got brakes I ordered one of their Zimmerman/Akebono kits that covered all four corners, rotors and pads. I only need front pads and rotors, so I was going to order the same kit, just for the front, and then send in my old pads and rotors off the front.

I'm using StopTech's 1-piece drilled and cryo-treated rotors and EBC Redstuff pads and have been extremely impressed with their performance on the street.Very good braking and fairly low dust and/or noise.
