New Brake Rotors
On my '85 RX7 GSLSE I found that I need new strut supports on top, (see alignment thread). I decided to replace the Rotors as well and ordered the drilled and slotted ones from Mazdatrix, (Brakenetics 45012). They seem a bargain at less than $90 ea. They came with new studs. I'm having a shop do the work and am concerned that these are not like the stock threaded rotors. Is it hard to install the studs? Will my shop have problems? Why the difference? I'd appreciate some prompt advice on whether its an issue.
Thanks,

i went with the same rotors. But i used a different stud (aftermarket from summit racing). I had no problems.
Its more likely cost since press in doesn't require tapping thus cheaper to produce.

Dear Whizbang,
Awesome, thanks for the response. These rotors are fantastic and i was just worrying about the shop finding it to be a problem or showstopper. Since by strut tower braces are deteriorated and broken, I decided to replace everything; rotors brake discs, shock strut cartridges, brake lines and wheel bearings. The shop is doing all of it for about 650$ Zoom-Zoom

If for any reason the studs don't press in right, then use aftermarket ones from ARP. Like if the stud is too loose. Ive seen this a few times over the years.

I bought extended studs for exactly this reason - increased thread contact to the lug nuts. Note that the pull-throuh studs have a heavy steel lug which is the clamping surface inside the hub. This is a stronger interface than threaded studs into the hub.
I've experienced no issues with the cross-drilled and slotted rotors since installing them many years back. The price hasn't changed much in that time, and the only issue is that they're not cadmium plated like they once were. My recommendation would be to sand them perfectly clean, wipe with acetone or other denatured alcohol, and the spray paint the non-braking surfaces with a good quality spray paint to protect against rust. If you don't, the rust in the holes and slots might bother you down the road.
