I don't know about those rotors, but I did buy cross drilled rotors from a seller on Ebay. They work great, but they are supposedly zinc coated and are not. No problem with craks or anything.

Okay guys. The cross drilling and slotting not only increases the risk of stress risers, but also significantly decrease pad thickness through much of the shaving. FWIW, there is NO performance gain, and I and other AX and RRer's know, especially since our sports tend to use brakes a lot. If you like the looks, okay, but there is no significant performance gain from the rotor face patterns, no matter what any user testimony may want to say.
The Zinc coating on the friction face will evevntually buff off, however if there was any rust on the rotor face, it would be eventually be buffed off as well. Therefore the Zinc coating helps much more with the surfaces that don't involve the friction of braking by yielding less corrosion, however the corrosion on the inside of the internal ventilation hasn't hindered the cooling properties of the rotor by much.
In short, if you want looks and don't mind risking a sacrifice in performance and/or reliability, get rotors with those fancy features. If you are concerned with improving braking performance by cost effective brake modification alone, then be concerned with rotor swept area and brake pad compound. If you want those rotors buy them for looks, not for performance increase. Any possible results any will claim with the rotors themselves will be mostly placebo effects.

Wow, Now thats a right up LOL. Makes sense and very good points, I do want them for the looks factor. It's not my DD or my race car just a cruzer that comes out a few times a month.

It just you forgot the one thing that goes against getting them for the looks- an INCREASE in brake dust. Of course, if you don't mind cleaning your wheels after everytime you go out, it shouldn't be an issue either...

Answering your original question: I bought these about a year ago. I've had NO problems with them, as far as cracks. They have warped within the last month, but in that year I've put 50,000+ miles on my car so I think I got my money's worth. Getting ready to buy another set from them. They look great with my TT2's and painted calipers!

I bought Baer Eradispeed front rotors on eBay, new, shipped to my door for $300. I know they were more money but over one year now, no cracks, no warping and great performance, rear ones are $280 just my .02...
