I was actually the one who purchased the brakes from Dave....I never opened the box nor did anything in between besides storing it in my house. I then sold it to Vince, when I brought it over and I opened up the box with Vince , it was packaged very nicely and secure. I do feel for Vince, I hope he figures out what the problem is.
I don't think this has anything to do with rotor refinishing or calliper spread or who sold what or who tracked what.
I would suggest it's math and measurement
Measure the rotor diameter to make sure it's correct for the bracket that's installed.
A 97+ bracket on 91 rotors would look just like what you've got.
If the rotor is correct then remove a calliper and check that the correct brake shoes are correctly installed in the calliper.
The brake pads may be too narrow or are too far away from the rotor centerline.
No point wasting time on tis taints.
Get out the digtal micrometer and determine the problem.
The solution will be easy after that

Not having read anyone's comments on here this looks like NA1 rotors installed with NA2 calipers.
Sorry if someone has already mentioned this.

No, daves parts are all correct. I think I have discovered the issue. I believe it has to do with the rotors not being cut correctly. The is a really and I mean really fine lip on the inside of the rotor near the hub, a high spot if you will. Its micro sized but it seems the cut did not got down enough and its lifting the pad at the bottom. You can feel the lip on the rotor and you can see on the very edge of the pad where that lip is digging a grove. it would make perfect sense that its lifting the pad and causing it not to touch all the way, thus the grove in the pad. Just ordered new rotors from SOS but I think that's the issue. Thanks for the help and sorry if I upset anyone
you may need new pads too, now.

I don't see how after 150 miles. They will wear down flat. However I just spoke to R1 and they said they only slotted them and didn't cut em. I don't know we'll see what happens Friday. Going to sand the pads and put them on the new powerslots and see what happens after the weekend
If the ridge is only on the inside of the rotor wouldn't the outside pad still sit on the outside rotor surface correctly?
If there is a ridge on both sides of the rotor then perhaps that might explain why the pads on both sides are not sitting correctly.
Did you remove the wheel and calliper to check the rotor finish?
Were the rotors the correct diameter?

The ridge is on both sides of the rotor. On the inside, I mean closest to the hub. If you look at the pics of the pad you can see where the front edge closest to the hub has a cut out from where it was riding the high spot, causing it to lift at the inside of the braking surface

You might want to bring this back to R1 concepts. Not expecting them to do anything, but it seems their "slotting" machine is defective; leaving an uneven surface on both sides of the rotor.

Just spoke to them. Useless.
fwiw, again just trying to help since i'd be a pissed off mess if I was in your shoes, I always go thru a bed in procedure when changing new brake components.

No one painted Dave as a villain, at least I didn't.

If the calipers were bent then yes I would have "junked" them. However, you should read all the post...."Dave, like I said not calling anyone out and to be honest, with out installing new rotors and pads to inspect you would have never known"
''Again, not trying to say anyone fuc#ed me, just looking to get it resolved.'' Never did I say this is Daves fault. Was I wrong about the issue, maybe but did I point a finger?? Nope

Indeed I was blaming the possibility of spread calipers on track use. What else could cause that?? But again, I did say that if that was the case I'm sure Dave didn't know about it. That's why I didn't blame Dave. How ever you decide to take what I said, that's not what I meant
I called jdmdohcpower and offered him a set of brand new slotted DBA rotors I had at almost 1/2 of retail price to help with the situation. A situation where I did nothing wrong, and the company that turned the rotors screwed them up. And mind you there was another buyer between us. And I sold my brakes to him rather cheap.
I'm glad it's resolved, I just wish that my word and knowledge of calipers carried as much weight at some guy that works at Acura and decides to say my calipers are "spread" because he's seen it happen to their "track car". It's a complete misdiagnosis and lack of understanding. My car was never a dedicated track car doing wheel to wheel racing. What my car has seen on the track is probably less than what many NSX's have seen on the street. JDM you have to understand my position here, and see how you'd feel if someone said to you "nope, your calipers are junk from your track use". It wouldn't make you feel good either. Honestly I was so confident in my brakes that I would have just bought them back had they not been painted blue and slotted. Saying my calipers were junk does still put a dark spot on my reputation on the forum, even if you say I may not have ever known. Trust me if my calipers were damaged I would have known.
Anyway glad it's getting resolved. I guess we can all just move on. Thanks to all the guys that tried to help with the situation.

I'm sorry for my choice of words. I guess it was said out of frustration. Thanks again for the help
No problem man, it's all good. Let us know how it all works out.
A caliper is a just a simple clamp and and brake pads are not precision machined parts so a little uneven ware until everything can find its place is perfectly normal.
