ModROTOR™ by NALLEN...

[nallen00]

Representing the culmination of more than two (2) years of rigorous computer-aided design and analysis, the ModROTOR™ composite braking system is NALLEN’s most prized work-in-progress. It is dramatically lighter (up to 50%+), stronger, and more thermally efficient (up to 30%+) than any cast alloy rotor from the competition, making it, unarguably, the most forward-thinking automotive performance brake rotor architecture in the world.

The following images show the ModROTOR™ Cobalt SS/TC alpha model with optional materials/processing:





Keep your eyes peeled for updates on our website, including an in depth technical description of the system, availability, and projected pricing. Of course, I'll be posting extensive coverage of prototype production and testing, including photos and video, right here.

I'm prepared to answer any questions you may have, but you'll have to wait for a complete background until the website is updated.

Thanks,
Nathan

Progress!

While we're waiting on material quotes, we decided to burn some 60% scale rapid prototypes on the Z Corp. We've already cut these several times in CAM, but wanted to run our fingers over it before making a commitment:







Problem with material is I'm competing for 17-4 with the aerospace and medical industries, both of which have deep pockets. The trick is locking in a supplier at the right size and price.

The issue with the core (shown above) is minimizing mill time. The vane pockets as shown are smooth, or .001" step. Bumping this to .003" step would decrease mill time considerably. The surface would be slightly more "rough", i.e. not perfectly smooth, but this would also increase surface area by ~3-5%, which is a good thing.

At this point, the plan is get the prototypes together in time for testing at Putnam in April, followed by their formal debut at Winged Warrior in May. Watch for a complete assembly mockup in the next couple days...

Ok seems cool but possibly overkill for a street car. What is the damage $$$????

Thanks! We're EXTREMELY excited to finally see this project coming together.

We originally designed this system for motorsport, which speaks to its modular architecture. 100% configurable. Aside from the obvious advantages of being significantly lighter, stronger, and running cooler, you buy replacement discs, not complete rotors, saving you on spares.

Pricing will vary significantly depending on the disc material: 17-4, 6al-4v, or CF. The Cobalt SS/TC system shown above w/ 17-4 discs should run in the $800-900 range at volume, $1000-1200 w/ calipers. I'm speculating, of course, since we haven't locked down the initial material costs...

I think our calibers are larger than a Cobalt of TC. Could be wrong though..

[nallen00]

I didn't mean to imply any crossover. We can use the factory calipers, or supply them.

In any event, only small changes are necessary to adapt this system to virtually any application. The fact that it's 100% CNC manufactured means that we can fit new makes/models in less than a day...

Well, I was saying $$ for the size and since the calibers are larger the $$ would be more.

Looks awesome... a blend between street and track... i would love to have 2 piece vented rotors! can these be resurfaced like standard rotors, or will they be like drilled and slotted rotors that can't be resurfaced?

Totally modular... Interesting.

6al-4v, Titanium?

You guys are really thinking outside the box... Have you done any small scale testing?

GM Parts Direct has the Cobalt's Brembos for ~$184, and the Camaro's for ~$84...

Thanks! It should be possible to turn them conventionally. Depending on the nature of the distortion, and because each disc has two (2) functional surfaces, it may be necessary to have them Blanchard ground.

Correct. All testing at this point is "in math". Among our services is simulation and analysis featuring COMSOL Multiphysics. We've run a 1000+ simulations over two (2) years, factoring every known force, both mechanical and thermal, in various performance and motorsport environments. Our first physical test session is scheduled for April at Putnam Park...

I like keep us posted!

I've got news for you, the factory brembo rotors are 32mm thick. The minimum thickness is 30mm. There's no way we will be able to resurface our factory rotors, with only 2mm to work with, 1mm on each side.

Racing Brake already has 2 pc rotors for the Camaro SS. I put them on my car 2 weeks ago. http://www.camaro5.com/forums/showthread.php?t=59008
