R1 Concepts Front and Rear Brakes and Rotors| Front and Rear Semi Met Brake Pads and Rotors Kit| Fits 2008-2012 INFINITI EX35; 2013 INFINITI EX37; 2011-2012 INFINITI G25; 2005-2008 INFINITI G35

Easy install, simple remove and replace. How ever, these rotors are surprisingly heavy, As I assumed they would have been "lighter". Pads are of good quality. Installed yesterday evening.. ( 8-4-17 ), So far, seem a bit noisy, and tends to "pull" a bit to the passenger side, but l give it a week or so, to "set in". I love the way it looks with my original Nissan black colored wheels, I have the touring model 370z so I do not have the 4 piston calipers, I have the 2 piston. While you do the install watch your brake fluid reservoir to ensure no leakage occurred when you push the caliper pistols back flush as to when you install your new pads. My car has only 30k miles, and I had a little bit of backfill when after I pushed the piston back flush into the calipers, watch this closely guys as brake fluid can destroy your cars finish and obviously makes a huge mess. Other then that, take your time, go slow, and this mod. Should go smoothly without issue. Ill do a follow up review as to tell you all about the noise and the slight "pulling" I'm having. All in all, great look, I'm liking it. Be safe enjoy your 370z !!Follow up: It is now 8-7-17 Monday. And I have no issues at all. No more slight drift to the right, not any noise. Perfect " wear in " no pulsing pedal, Still looks great very nice upgrade, well worth it. Highly recommend it.

Easy to install and fits perfect!!! Great upgrade from oem!!

The brakes from R1 Concepts are made to high standards. I could tell a huge difference in the brakes from R1 Concepts. This is all for brake rotors with brake pads. This did not include hardware (new brake pad holders/mechanisms, I just used the old ones). The stopping power has dramatically increased in my Dodge 2016 Grand Caravan R/T. There original problem that I had with my OE brakes was mainly over heating, which would cause the brakes to overheat and become warped. My OE brakes were not meant for the speeds of the German Autobahn. The Grand Caravan especially had it worse. I would experience extreme steering wheeling shaking, cause by the overheating brakes at little to no braking at 80MPH+ speeds. The times where I need to Brake hard; mainly due to slower cars jumping in the speed lane, or the constant on and off of construction. The new brakes from R1 Concepts are amazing and exceeds my expectations. I no longer have that violent shake, cause by the over heated, warped brakes, happening as I break. I have breaked at multiple speeds multiple times and I only slightly experience and shaking of the steering wheel caUse by brakes. ( Happened once with full passengers, with luggage, going 180KMH, max limited speed. It was very light and the van stopped without a problem) These brakes do allot of work to stop the huge van alone plus the extra weight that I am always carrying in it (family, furniture, and luggage). The brakes also have a stylish look to them. I enjoy the look especially. The brakes have made my Grand Caravan allot safer than the OE brakes. My family and I feel safer cruising at the high speed of the Autobahn, the right is very smooth and enjoyable, especially now, with the braking allot less scary and allot more trustfully.I am overall extremely satisfied with the brake from R1 Concepts. I have had the brakes Install for around 4 weeks. I have taken multiple long trips at some fast speeds and the car brakes exceptionally. These brakes do fit in the front dual piston brake caliper.

I have a 2017 Kia Optima EX with 2.4L engine (non turbo, non hybrid). Ok, so my factory brakes started to warp/pulsate around 30,000 miles and I decided to get this kit. First impressions is these rotors look awesome. Drilled and slotted looks so good. Brake pads seemed high quality too. Install was a breeze, took maybe 1 hour to install both front rotors and pads. Make sure you buy a tube of brake grease to do the caliper slide pins and add some grease to the back of the pads to stop any potential squeal. Brakes look amazing on my Kia Optima and perform as good as they look. I have 37,000 miles now and zero warping, zero pulsating, zero squeal, nothing. Brakes are super strong. Powerful stops. Much bettter than OEM.

Rotors looked terrific when I received them! For those misunderstanding, YES the sacrificial zinc coating comes off the rotor face with use. And YES It is supposed to. The coating is for the remaining portion so it doesn't dissolve into a big centrifugal rust flinger. I don't recall if the vanes (interior) are directional or not, but I will update when I take another look. Pads are fine, the quality of mine were great. Not something to use at the track but perfectly silent and effective otherwise. The smaller diameter rotors are for the Focus ST's produced on/before March 31, 2014 (320 mm). The larger 335 mm front rotors are for those produced after that date. Rear rotors are the same for both. Which... Brings me to the reason I didn't give a five ⭐ review. This is partly my fault for not checking thoroughly, but I received two sets of front pads and rotors instead of a front and rear set, which were all in one large box. Sincere condolences to my delivery guy :/ I had a lot of back and forth with R1 Concepts and Amazon, trying to figure out what to do. They wouldn't let me return half the order, only the entire 80lb set. I ended up selling the extra pair, but I could only find one manufacturer making a rear set of slotted and drilled rotors for my ST. Oddly, even R1 Concepts doesn't seem to offer just the rear set for sale. Anyhow, learn from my mistake, check your order. Lastly, as I said, I'm not sure if the veins are directional or not, but take care to install them on the correct side of the vehicle. Unlike regular rotors, these have a specific orientation, with the slots & holes running away from the center when driving forward, not inward. Despite the packaging error, these have been great so far, but double check your ENTIRE package to be certain. Rears are noticably smaller than the fronts.

Smooth install, no issues. Recommend to buy lubricant like I did. (Purple bottle in pic) delivery was fast

Brakes and rotors are good quality and a perfect fit. Only knock was no brake hardware, which was not a big issue. Gave four stars for that reason only. Want to finish my vehicles front brakes but our if stock unfortunately.

Brakes seem to be of good quality. Installed on a Chrysler 200 and made a big difference from stock. Only thing is they took a while to ship and I wished they came with new clips for the Brake Pads.

The break pads should have included new mounting clips, had to reuse old ones. Other than that I am completely satisfied.

Great Product, Good price Fast shipping and interaction with seller is quick .
