On ebay for $50 + 35 shipping for a pair. Curved vein, Zinc platted , Slotted only, Not drilled.
I just talked to the guy on the phone, good guy, 909-626-8537, he has about 200 pairs left.

I've tried plain, slotted, and slotted/drilled and 'slotted only' are by far the best option in my experience. Now you can afford those Porterfield pads you've always wanted!

What size are these rotors? I didn't see a size listed.
I assume they will need to be redrilled for TBirds correct?
But what is the diameter of the rotors?
Thanks

Cobra rotors are 13"...

They're Cobra rotors, 13" , 5 x 4.5 lug pattern. They will need to be re-drilled to 5 x 4.25 for T-bird hubs. It's just a great price. Re-drilling a T-bird bolt pattern is a piece of cake even with a hand drill - just use a good template. If you need a template then PM me.

The R4-S compound is for street use. They're not cheap but they are worth the $$.

"You get what you pay for".
I got these rotors and they are not worth the time to put on the car. They were machined out of plane with the casting. The individual discs vary significantly in thickness, though the overall thickness is consistent.
"Mike" says the entire lot is like this but he hasn't heard any complaints.
Take a look at the pic, the top side is way thinner. When you rotate it 180 the top side is the thick side.

Sorry if anyone bought rotors from this guy, I should have waited to inspect the product before recommending it.

Did you actually measure the difference with a caliper?

The top side measures 0.265", the bottom measures 0.369" at greatest delta, of course they are equal at roughly 90 degrees, then opposite at 180. Not worth the time to remove and replace much less the time to re-drill the bolt pattern. Lesson learned.
