I'm usually on another forum and I was surprised to find that only two people had heard of them. I was cautioned on the cross drilled and how they might crack. My car isn't a daily driver. Have you ever heard of the cross drilled rotors cracking or warping?
I had read about them on this forum, and I just ordered them. I also got Centric Posi-quiets (or whatever the pads they are selling) pads. They are currently in transit to me. The people were real helpful. Tell them you are on the forums and if you get fron at rears they will do it for like 529.00 for the rotors free shipping. That is for the SRT8 rotors though.
I will let you know how they work. I have seen nothing but positive feedback on the forums regarding these parts.
And yes you dont track Cross-drilled rotors, they will crack. Road use is fine though.
I purchased the slotted/cross drilled from R1 for the front and rear last year once the oem's warped. They are much better than the OEM, better stopping and no warping issues to date. Customer service is great as well, UPS lost one of the boxes on me, Steve replaced the box with no problems. Good service and great pricing is hard to come by these days.
While I agree that the posi's do have some issues, and I let R1 know that, my experience with the stock setup has left a bad taste in my mouth. If I were to use the stock pads and the new slotted rotors I am not confident I wouldn't have the same issue another 25000 miles down the road.
I am confident however that these rotors are a far more durable and reliable piece of equipment. Besides, they are lighter (any time you can lighten rolling mass that makes a big difference). They only cost 125.00, (500 shipped for 4 of them from forum members) so the extra 120-130 overall for the piece of mind that they will last longer is great. Plus if I went with the stock pads they cost more than the rotors. Oh and the cross-drilled/slotteds look GREAT on the car. I would absolutely recommend them again, just with a little more performance oriented pad.
