These could be better for racers even if a little heavier if they last longer and the replacement rings are cheaper than new OEM rotors.
Is the missing chunk part of the balancing process? |

Adding additional weight can't be beneficial in this context as the Car is already heavy so it will make more sense to reduce the weight by any means necessary. Best to stay OEM than to take this route.

All,
We have been away from the forum due to other commitments keeping us busy but I'm going to address a few things here, especially the unfounded claims made by Dasky Spas. This might not be the greatest PR reply but as a business that invests time and money into offering high quality aftermarket options, we do have the right to defend ourselves. 1) The two-piece discs have 2 hardware options. The one you guys see on the website was improvised where there is just enough room for expansion (you won't be able to move the disc by hand) to prevent cracking. The reason behind this was that the other option was adding a hair over a LB to the weight. This same design has been in use for over 3 years on some of our initial adopters (including other platforms) and there hasn't been a single issue to this date. However, if you require the other hardware setup to add more gap, we are happy to do that since customization is our niche. 2) Weight concerns- The OE BMW M discs are extremely light to begin with. This was addressed above on 02/07/2024. Now to clear up the claims being made by Dasky Spas- please bear with us because this is going to be long but needs to be put out there so other members can see through this themselves. Said individual owns an M850i (pay attention to this one) and wanted a solution that is lighter on both axles. The size of the M850i front is the same as the F90 M5 but the construction is different (he was made aware of this). The M850i OE rear is a totally weird size and design which does not permit a 2-pc construction. He assumed and is still fixated on the front being the same as the M5. The data in our systems shows that the design has minute differences and our job as a custom product supplier is to ensure that there is 100% compatibility. Would BMW supply an M5 disc to him for the M850i and guarantee fitment as well as performance? Not at all. But going back to the basics- we already provided him a lighter front setup than his M850i. The rear setup was a custom solution as well that required hours of work from our two engineers. We provided him larger rear discs with better calipers as well as our newly launched solution for factory EPB compatibility. Mind you guys, we discounted the whole setup for him because he had been pushing to get a sponsorship from us. Once we realized that the rear setup has to be fully customized and will add to the cost, we even offered him a full refund. But he wanted to proceed with the alt solution. So that is what was done for him. In the mean time, he emailed us about comparisons with the M5 front discs again and we had to address those. Fast forward to him receiving the package, initially he said everything looked good but then the email rail-gun turned on. He went back to comparing with the M5 discs and we had to address that again. I am not sure what it is that he doesn't understand- his car doesn't use the M5 discs. But he is stuck on it like superglue. Since we shut that down, he mentioned how the quality is questionable since the discs are made in China. Just because something is made in China makes the product questionable? Brembo-AP has been making it's products in China for over 25 years. So I guess they need to be questioned as well. BMW needs to be questioned as well since a lot of the parts in Euro cars are manufactured in China. Would people be ok with us lying about where these are made? We have always functioned on transparency about where our products are made because quality is a matter of enforcement and not the region of manufacture. But the individual has strong racial/regional biases and it clearly shows. Then he said there was no anti-corrosion coating on the rear, which was false and we pointed it out. The only difference was that the front OE discs have a different coating vs the big brake rear discs since both the lines are different- and we explained it to him. Then he has issues with the slots (machining pattern) on the discs not being polished on the inside. This is just hysterical. The purpose of the slots is to increase the friction on the disc surface and we cut the slot pattern that he asked us to. But the increased friction is somehow dangerous according to Mr Brake Expert. Then it came to him saying the front and rear hat designs are different- when it was clearly explained to him that his front is OE design replication and rear is a custom disc focused on as much weight reduction as safely possible. Mind you, this wasn't an issue initially but since we didn't cave in to his arguments about the M5 discs, this also became a problem. Then he moves on to crying about no washers being present. We explained that the M8 size bolts used with the disc design have plenty of surface area to spread the stress and washers would be required on smaller bolts, but he responded with the same statement- washers are not present. Then he moved on to the bolts being off shelf and we explained that the bolts are common size so when the time for replacement comes, if someone damages a bolt, they can source those locally instead of having to go through us. So then he says that we use low quality bolts and our discs are not safe- which is slander because we use metric grade 10.9 bolts that exceed SAE grade 8 hardware strength (also called heavy duty car bolts/hardware). Then he moves on to the small slivers of metal that are shaved from the inside lip saying how rotors can't be balanced because metal is missing. This is because Mr Brake Expert has zero knowledge about how brake discs are balanced- small slivers of metal are shaved from the inner lip (facing the vanes) of the side that is showing slightly heavier on the balance test. This is standard practice and every brand's discs have the exact same patterns of shaved slivers (including OE discs). All this time he has been pushing us to give him half his money back and when we respond with factual statements to his opinion filled emails, he throws a fit and asks for a full refund. Our policy clearly states that unless there is a manufacturing defect, we don't offer returns on any custom orders due to the inherent nature of the products. Which is where he keeps looking for something to create a fuss about only to be shutdown fairly easily. He has been sending us nasty emails and texts hoping we would cave in to his demands. Our apologies for the long post but this was required to clear the air and also expose the individual for his false claims. If this means that some of you folks won't trust us, then we will be fine with that as well. We do not sit back and take BS from individuals who keep bullying businesses so they can have the products for free or extreme discounts.

Please read the last reply. You are more than welcome to check with individuals who have been actually running our brakes instead of folks who are reaching for something so they can get some of their money back.

All our hardware is tightened with hand tools. We never use impact guns- we have videos and photos of our processes to prove it. But you keep making false statements. Your front is OE replication in a 2pc design while your rear is a custom disc meant to reduce as much weight as safely possible. We could have made an OE like disc for you for the rear, but looking at your antics, then you would have whined about the rears not being light. Edges have slivers shaved in order to balance the rotors. Metal is never added after the production is complete. Go check brembo, AP, RB, Giro - it's the same. This just shows how you have zero knowledge about these things but want to play keyboard warrior.

All our designs go through over 120 heat cycles during the design process to ensure that nothing bends or cracks. Additionally, each rotor ring is put through extreme heat treatment before it is used for the full disc assembly. This ensures that if there is any ring that is expanding in an unacceptable manner, it is tossed back into the furnace and a whole new ring is utilized instead. Replacement rings are cheaper than new OE rotors, yes. Missing chunk is not actually missing. Those sections are shaved in slivers to achieve balance. More metal cannot be added to the lighter side after the discs have been made. Every brand's discs have these small sections shaved from the inner edge of the side that shows up as heavy on the balance/true test.

Washers are used on discs where the hardware is smaller and narrower. On most of the discs though, we use M8 bolts which have a wide enough stress distribution surface and there is no need to use washers. Also, the marks on the discs are minor surface marks caused by the handtools used to tighten the hardware to spec.

Our job was to provide you a 2piece disc that mimics the M850i and is lighter. We did that. But you are still stuck on the m5. Keep at it because we won't entertain it at all. As far as the data goes, no- we are not going to provide you or anyone with our proprietary data that we worked on. You are just making yourself look worse with every response and email.

TritonMotorsports, at the risk of you coming hard at me also, and with conceding and admitting off the top that most of the technological discussion is beyond my expertise, I’m going to just state that coming after and bashing your customers (even if they are in the wrong, and I don’t know enough to know whether Dasky_spas is or not) is just bad business. We’ve seen this happen with Project Gamma and serhat06 and the like.
You are a company, you were mentioned negatively, and you have the absolute right to respond to your naysayers. But there is a proper decorum and tone to set while doing it. You may be entirely in the right here, but boy do you sound bad doing it the way you’ve done.

A customer making baseless claims and bashing a business to hurt them is ok, but for a business to expose that customer’s antics in order to show everyone what the situation is, is somehow a huge “no-no”? I am sorry but some businesses work hard on their products and they have bills to pay as well. No reasonable adult would say that you should just cave in when a customer throws a fit. Like I mentioned in my response earlier- this is not the most PR friendly post and even if it means losing some potential customers, it is fine. The goal was to defend our products against baseless opinions.

I never stated that you aren’t allowed to defend yourself, or that comments that were made about you weren’t egregious (again, I don’t know everything). But you went to personal attacks and arguably some ad hominem statements (again, even if such comments were made about you first). I’m really not trying to argue with you, nor am I trying to stir the pot. I’m not your customer (not because of this situation, but because I’ve got no reason to mess with my OE rotors). But we’ve seen multiple businesses shoot themselves in the foot going the route you’ve gone. It’s usually caused forum members to swear up and down they’d never purchase from such companies. If I was a potential customer, this would be an instant turn off for me. You could have asserted your defense more objectively. But hey, it’s your company, your product, and your right to free speech! This wasn’t meant to be a fight or argument, just a casual, unsolicited observance. You’re free to disregard it and me!

Other individuals also asked questions here or on emails and you can see our responses. But for someone to just look over the logic and facts, and start slander- we don’t sit back and take it.
