    Gonna need to replace my pads soon. Does anyone know where to find the TRD pads for 2016+? Can only find 15 and back.

    I don’t think the TRD performance pads are available yet for 3rd gen.

    I’m trying the StopTech sport pads along with there cryo rotors. I’m going to look at some Trd pads at the dealer tomorrow to compare them to stock, pretty sure there the same size. These pads are listed for all second gen, third gens, 4 runners and fj’s. They also require similar break in as the trd’s.

    I have my stoptech rotors and TRD brake pads installed for 500 miles now. I noticed a scratch on the inner diameter of the rotor above the black circle. Running a finger over it feels like a scratch too.

    Is it a scratch or is it just an area where the pad doesn't contact the rotor leaving that surface un-smoothed.

    Just did this upgrade on my brakes a few weeks ago. They broke in very nicely, and no more shudder during braking! I was surprised that mine needed replaced after only 60K!

    You're right, the pad doesn't contact that portion of the rotor. False alarm!

    @crashnburn80 Have you looked into this company? https://www.r1concepts.com/

    They have a large following online. Their products look to be high quality, but I’m not sure if their marketing average products to less educated consumers.

    Their coatings do look nice. They even offer a big brake kit with 6 or 8 piston calipers. Their social media pages show their products in race and off road environments.

    Have you heard of them? When I do my brakes next, I am going to have to decide between DBA and maybe them. The R1 price points are much better from what I can tell.

    Yes I’ve seen them. If you look into the details about their performance series stock size rotors they specifically call out they use the OEM cooling vain configuration. They claim some minor enhancements like coating the veins for smoother airflow and it looks like mildly shortening every other vein for ‘split core’ veins for claimed better airflow. None of these techniques increase cooling surface area which is critical for heat dissipation, and their split veins would actually very slightly reduce surface area. They also do not increase the mass of the rotor which helps with heat saturation. They are not a reengineered rotor design like StopTech and DBA.

    Cool looks is what many use to sell rotors, and very successfully. However real performance traits of a rotor are not going to be externally visible or look cool, they will be internal on the rotor design. Very few actually spend the R&D to redesign the OEM rotor, especially when you can pass off the OEM design as a performance upgrade.

    Hey, so, do you still run the setup you started this thread with? How has it been, and how is it holding up?
    If you had to change things out since post #1, where are you at now?

    I want to pull the trigger. I replaced my 2010 Sport OEM pads with Wagner ThermoQuiet pads about 4 years ago. OEM pads lasted forever, and the Wagners did/do not impress. Will even consider replacing rotors, even though I'd have to deal with braking red loctite from my spidertrax spacers, but oh well.

    Anyway, thanks for the write-up.

    Still on the same setup, TRD ceramics are very long lasting. I go back and forth. The performance OEM ceramic pads are ultra quiet, the dust is very fine and not very noticeable on my grey wheels. It is enhanced performance over stock while still having the positive performance characteristics like stock. Sometimes I think about going to semi-metallic for better cold weather performance and initial bite, but it would cause massive brake dust, noise/vibration and much shorter pad life, which I’m not sure is worth it.

    Keep in mind the pads determine bite and operating temp range, the rotors determine thermal capacity and cooling, aka resistance to brake fade. I would buy the StopTech rotors again in a heartbeat.

    Excellent. Thanks for the follow-up. I went ahead and ordered the rotors and the pads. Current Amazon price for a rotor is about $137, and the pads run $99. I need something new. I tolerated bad brake performance longer than I should have. Anyway, thanks, again.

    As a random datapoint, I have had 3 trucks that I have put drilled rotors on, put over 100k on each and never had any issues with cracks forming.
    The last two I was aware that the holes did nothing for performance but what can I say, I like the look of them.

    Current daily driver has drilled ones because I couldn't find Lexus IS-F rotors in stock that were slotted only. StopTech does make them, they were just out of stock when I ordered mine.

    I did a Lexus IS-F rotor, Tundra caliper brake setup on my truck. There is a guy on the X-Runner facebook group that does small runs of the caliper adapter brackets.
    Used Stoptech rotors and braided brake lines, brand new Tundra calipers and EBC green stuff pads.

    Great upgrade for the 5 lug crowd.

    Richie,
    I myself waited for the gentleman to make a run. I then realized after a long wait and more research the rotors are rear rotors for a Lexus, design to have a parking inside i.e. Added weight. The calipers are cast iron i.e. more weight and the adapters are thick heavy steel plate even more weight. Sprung weight may not matter so much on Pre-runners & 4x4's but it does the lighter the vehicle gets. Driving light weight cars you can really feel it. So I decided to go with the Stop Tech / Tundra racing BBK with two piece rotors. The stock brakes with rotors and splash plates were 29 lbs. (if memory serves me right) The kit weight saved 4 lbs. (alloy top hats, alloy calipers & alloy adapters) So between losing 6 lbs w/ lighter weight forged wheels and the brakes the ride improve! Plus I can now do nose wheelies‼️
    Now I just need to install the QA1 coilovers & URD SC setting in the garage.

    Those 2 peice rotors are nice! I looked at them for the 6 lug but they are quiet spendy by comparison.

    I looked at that same kit as yours and almost pulled the trigger on it.
    It came down to money for the most part, parts availability being the other. In a pinch I can find all the parts at the neighborhood parts store.
    This truck will never see track days, it is my work truck so squeezing that last 1% of performance out of the setup isn't too much of a concern.

    BTW, cool seeing a built up 5 lug that isn't an X-Runner. Almost went the 4 cyl base route but got a good deal on the X.
