INC. 121.45041 C-Tek Standard Brake Rotor

Used on race car. Seems Mazda Motorsports also sources C-Tek (referenced in their part number). Only issue was that I had to open up the stud holes about 1mm to > 13.1 to match the rotor I replaced, otherwise the rotor would not fit over the unthreaded portion of the stud. I presume studs are OEM - they are not extra long.

Nice looking rotors. If I'm not mistaken, all 2003 and up Miata's have the larger "Sport" breaks as standard equipment. From the description, there's no way to tell that these won't fit. Amazon's configurator say's they do, they Don't.

Worked well, and removed the shimmy i was experiencing. Just use brake cleaner before you install. time will tell if they hold up.

It's a brake rotor. It's metal, it rusts, what else is there to say?

Good basic brake discs. They do their job. Spend your money on good pads and save on the discs.

Cheap and lasts a reasonable amount of time. No fitment issues on a 1995 Miata.

Works on my racecar.

Great

Ordered a pair of these and both of them are scratched in a straight line across the center hub. Thankfully it's just surface level mark and not an actual crack. It seems like a cosmetic manufacturing flaw, but still not very happy about it and won't be ordering again.
