I found these rotors and pads fairly cheap compared to other brands so I was a bit skeptical. After doing some research I'm ready to make the purchase and try them out. Here is the list of parts I'm getting:
2010 INFINITI G37 Coupe; X; without Sport Brake Package
Front and Rear, Drilled and Slotted Rotor, silver
Part No - 631-68010L Rear
Part No - 631-68010R Rear
Part No - 631-68011L Front
Part No - 631-68011R Front
Brake Pads
Optimum OEp - 1551-1287-00 Front
Optimum OEp - 1551-0905-00 Rear
Brake Hardware
340-67040
340-68008

Few questions I have for you guys:
Should I get these Optimum OEp brake pads or the Performance Sport?
Should I get the black zinc coating? (I know the color will wear out but I think it'll look nice inside the groves and middle hub of the rotor)
Is going with the drilled and slotted option a good decision? (I like driving the G hard, almost like on track but daily)

Any feedback is much appreciated. Thank you

 

Slots and holes are for looks only on street cars. Get solid rotors for performance. Can't speak towards the pads other than to say I am running Hawk 5.0 pads with my Akebono brakes. They squeal when cold and groan at low speeds when warm. But, #racecar. I do track my G now and then, the pads made a difference.

 

I got rotors from r1 concepts years ago for my 2007 G35s sedan and used them again in 2015 for rotors on my 09 BMW 328i coupe and they were great.

Lately I have been looking at them and their web site does not inspire confidence. If you end up purchasing these please update us with how it all worked out.

Also, if you check Amazon.com R1 sells their e-line rotors there for less than their site most of the time.
