Have you tried calling them? I've emailed them before and their turnaround time was not bad, but I had better luck calling.

 

just swapped rotors. the noise is gone. this is a HORRIBLE design flaw. I better get a full refund. Also tried calling, no one picked up. I don't have time to deal with this BS. uploading video right now...

Also, no email response yet. And looks like the G35 drivers are having issues with R1 Concepts as well.

It's a shame that you've had problems. Fortunately, I haven't had any problems with my rotors.

sorry for the horrible quality video. but you get the idea.

yeah, it really is since a lot of lexus owners seemed to be happy with their product. I swapped back to my OEM and I think my R1 Concepts were slightly warped also since I have less vibration under braking. Sad I only had them for a month and only used for daily driving.

 

Update:
finally got a hold of them...and I'm really confused with their customer service. I talked to their reps and he was really nice. He's sending me a new set of rotors and a shipping label so I can ship one old rotor back and they can inspect it.

GSTeg, you were right, they do stand by their products. We'll see how these new ones do once I get them.

 

I am slightly confused, shouldn't you have serious issues with lug nuts loosening if your rotor is able to move between your hub and wheel. Torquing the assembly down should keep everything locked down? There will always be a slight over sized hole with brake rotors as they are hub centric not lug centric.

it's not moving between the hub and the wheel.
the rotors are moving within the over-bored hole for the studs. click on the video, not the best quality but i think it'll explain better.

 

not the best quality is a understatement. did you 4get to pay your light bill or did you choose to for go on that 2 get said rotors? j/k that sucks i read the review from the gs forum too (well like 4 pages of it then said enough is enough) they mainly just had a issue with it rusting and some yahoo dude being a **** on there!

 

All rotors will rust to a degree, unless the hub part is anodized or coated with powercoat.

 

I'm a poor college student but I can still pay my electrical bills lol. it was more like my light bulb just burned out and I didn't have any other source of light.

well, I've been running these R1concept blank rotors for a while now and so far no huge mechanical defects.

I got brand new set of rotors drilled to specifically fit. I think it's sliiiiiiiiightly warped but besides that, no issues. Does a good job at stopping for street driving.

...d'oh, i forgot to do this!
