I finally got time to install the new rotors that I ordered from R1Concepts.com. I chose the drilled and slotted rotors (just front) and purchased Black caliper paint for the rear calipers to match the OEM front calipers. The kit also comes with the excellent brake cleaner as well.

The caliper paint is no joke! It's the best paint product I've ever used on cars and it goes on even and smooth. The paint is still wet in the pictures.

The front Rotors and calipers on the Genesis are a breeze to remove. There's only 2 bolts to remove the caliper and 3 screws to remove the rotor. Stainless steel brake lines are next!

Looks very nice.

Just watch-out for crack around the holes as you use the brakes. Very common with cross drilled rotors. Especially if you use the brakes very hard.

That is why slotted and dimpled rotors have become the prefernece of many high performance drivers.

Good advise. I think the key to avoiding problems is to purchase a quality product. I've had drilled rotors before (Summitracing.com) and never had one problem, and I don't expect to have problems with these either.
 
Looks great! So far I only heard good stuff about the G2 paint we carry. They are a little more expensive then the stuff you can get at the auto store, but the G2 are rated at 950F the other stuff is usually at 450F.

As far as cracking because of the drilled... Well around 6 of us here in the shop got drilled and slotted rotors on our cars. Some had them on for a few years, and no cracking or heat stress marks. Yes it is possible for the rotors to crack, but that is somewhere around the >1% mark. And if they do crack, we do offer a 1 year warranty. So if it crack, let me know and I will ship out another set. Only time I seen these crack was from a guy tracking his Camero. For a daily driver you should be fine. Just enjoy them!!!

Scottdk:
The OEM brakes on the 4.6 have monstrous stopping power. In terms of functionality, is there a decipherable difference in pedal feel and performance, or do you gather it's more aesthetic? Love the look of the cross drilled on your black 4.6.

How many miles did you have on the car to replace pads & rotors or did you have money & labor to burn?

Sure it's aesthetic, but I'm into the performance aspect of it, and explained above, gases can have an escape route under braking, and these rotors will disapate much more heat vs. the OEM rotors. Are many Genesis owners going to ever benefit from something like this? Nope. When I'm driving "spirited" this will assist in the braking performance especially when doing higher speeds. Not many people who drive a luxury car are big into performance, vs a Mustang owner etc., but I'm well aware of the powerhouse under the hood and I use what I purchased.

19,000 miles. We all have money to burn don't we? If we didn't we would all drive Corrolla's.:D

Just like my OEM airbag, I'll sell the rotors online as well. I may have to wait until the car is a little bit older where people have racked up some miles and are in the market for new rotors, but they'll sell as always.

Want a spare set in case you buy a V8 in the future??:D

It only took me an hour start to finish (clean-up, cleaning brakes, etc. etc.), but the temp in the garage was 110 degrees so my clothes were soaked when I was done. I enjoy working on cars:)

:D Well on my Hyundai changed them at 22,000. I think I still had about 50% life left in them. Mainly did it for the performance upgrade. And they look so nice~ I think if you have rims, this will make your car look a lot better.
Plus you do the install at home, you save on all the labor cost.
 
Looks real nice! I would like to do the same myself. I think it would look good with my wheels and show through quite well.

Out of curiosity, did you call to order them? I go to the website and the Genesis is not even listed among the available applications on the r1concepts website.

Yup, I called the number listed on the R1Concepts rotor thread. There was a little delay in shipping, but I was told that the program for the Genesis wasn't yet uploaded into the CNC machines that produce the product, and then the same day the rotors were shipped. This would explain the website not updated yet. Worked out just fine.

Scottdk your absolutely correct. You were our first Genesis customer. So when you get the first batch we need to program the machines. And we need to make sure the program does not drill into the vanes and etc.. So there was a slight delay for that, I do apologize for that. But the next customer we wont have that issue.
 
UPDATE -

I like the caliper paint enough that I bought some for my brothers Subaru Legacy GT Limited since he wanted it done, and I will be ordering another kit for my Sonata.
 
Similar upgrade on my '09 4.6 at 19,600 miles. Rotors were warped. Actually... that seems to be a fairly prevalant problem on the sedans, at least on the early ones.

Had a couple mm before squeal tabs hit. Rotors were edged pretty good. Did this upgrade with ceramic pads to try to keep things a bit cooler.

Were you at the track weekly? The rotors on the Genesis 4.6 are excellent. I've beat the hell out the the new rotors I've put on, but the OEM rotors are the best I've ever even seen. Maybe you should purchase my OEM rotors I have laying around:)

Nope... no track time in the sedan; gave that up years ago. All my miles are basically up and down the NJTP... lots of 85 to 10 and back to 85 cycles in any given nearly every time I drive. Just about through the OE tires at this point, too. Rotate every 7500 etc. Just a lot of heat cycling.

I suppose I should have located my old IR temp gun and taken some readings, but haven't dusted that thing off since I dumped my last 911! :-)

Good to hear that the OEM brakes held up well for you. I am hoping the coupe's brakes fair better...
 
I just wanted to give an update on this old thread. I will comment that I still really like these rotors, and I can still see a little bit of the machining marks on them even.:) That's one thing I like about drilled/slotted rotors is that they take heat very well and never warp (nor can the rotors be turned). I would say the most evident braking difference between OEM and these is the initial bite of the brakes when applied hard. They bite very hard and don't fade or let up at all, even at high speeds which I have tested many times. My brother also has given positive feedback on these rotors to me, which I installed for him quite a while back on his Subaru Legacy GT '05.

I installed the same rotors on my Sonata, which needed all 4 rotors and pads done, but I installed the OEQ blanks of these. Original equipment quality is what it stands for, basically same high quality rotor, but not drilled or slotted (blank). I am currently running the OEM brake pads with these rotors........I know, I know:rolleyes:, you change pads with rotors:D

Hope this helps in the future.

Well said! I have a 3.8 Track A/T Coupe that of course came stock with the Brembo braking system, but that didn't stop me from getting drilled and slotted rotors and better pads also; in fact, I did the same thing to my 2009 Sonata 3.3L V6 Limited right before I traded it for the Genesis Sedan, lol! I'm looking forward to doing the same on my Genesis Sedan, but all the way around! Once done, I'll post up pics! HAPPY DRIVING! ;)

Wow, you may be the first person I've seen that has both a Genesis Coupe and a Genesis Sedan.

Well, a perfect storm of repairs hit my on the BMW's that preceded my the Genesii. With a history of "premium" vehicles (http://home.comcast.net/~corporatepurgatory/images/g/fleet.htm) that always seemed to need some sort of mechanical/financial attention, I was ready for a change. I have not been disappointed.

Brakes on the coupe have held of well; much better than the OEM had on my sedan (for me, clearly others have had different experiences) . I only have the GT coupe, so no Brembos there. I am at 22k miles.

The x-drilled/slotted rotors have also held up well on the sedan. I am at 34k miles now. An occasional shudder at low speeds, under light braking, and after the car sat for a week or so, but it goes away and stays away with consistent use.

So, the brake quality is not the sole variable here. One of the things I got zealous about since having to replace the brakes so early is retorquing the lugs to the middle of the proper range of torque after anyone else does anything with the wheels (rotation, state inspection of the brakes, etc.). As you guys likely know, overtorqued lugs exacerbate heat in the spindle through both generation and retention. I figured it wouldn't hurt to get back this in case it was the culprit... perhaps that was my earlier problem. -j
