The general IQ level at SEMA seems to have dropped recently

With shit like this being exhibited...

All I can say is... Wow. Brakes are safety systems... I hope for their sake these people have liability insurance.

:lol: :lol: Thats funny. I wouldn't trust those at all.

O M G.

I *really* hope those Willwood's are just the caliper on a homemade rotor.... I'm no engineer, but I'm pretty sure that rotor's a little big. :roll:

The other 2.... we'll, a pair might work well on the front fork of 400lb motorcycle, but I sure as hell wouldn't drive a car with those on it.

That's what it looks like... somebody took a Wilwood caliper and stuck it on their own dookie-ass rotor. It's got plenty of bling... never mind the fact that the caliper is using less than half of the available rotor surface.

Yeaaaaaaaah.... I love the ZMI website (http://www.zmibrakes.com/whyzmi.html):

1. ZMI rotors are born from aerospace grade titanium for unprecedented weight savings and uncompromising strength.

*Sniff* *Sniff* What's that smell?

Even if they used a high-grade titanium with a really high yield strength, the Young's modulus of titanium is roughly the same as cast iron - so with about half as much material there from using an unventilated rotor instead of a typical ventilated design, the rotor will flex about twice as much for the same amount of load.

A patented design is cut into the rotor to allow for the "active cooling system" to take effect. This cut allows the rotor to expand under heat in such a way that air can enter and cool the rotor more effectively than veins or cross-drilling. This design guarantees that your ZMI rotor will never warp due to heat.

*Sniff* Hmmmm, yep... I smell bullshit. No question.

I can't even believe I'm reading this. Allowing the rotor to expand for more effective cooling? Even with an 800F temperature rise under severe braking conditions, a 2" long slot like the ones they cut in their titanium rotors will only elongate 0.00784 inches. Wow. I'm speechless, guys. Your space age materials, cutting-edge engineering and innovative design might get a whole 0.0000000493 CFM more airflow through that dookie little slot.

And I don't think I really even have to go into why cutting all those channels and slots in a solid piece of rotor metal is a bad idea purely based on structural strength and safety reasons...

You know, instead of spending $4000 on their brakes, you could simply stack all that money in a pile on the floor and light it on fire. It would be a hell of a lot more entertaining and safe than actually trying to use those things on your car.

BWAAHAHAHHAH!!

I believe that needs to be copied into an email and sent to their company. Post replies here. :lol:

Well if I saw them on a REAL car and not just some show car i would be scared :shock: to be near them..... but if you ask me they just going for BLING and not effectiveness :wink: not that impressed with non functional things :roll:

I can understand the bling idea, for show cars and the like... but I wouldn't trust those rotors to be safe just driving the car from the trailer to the booth at the show.

If I was only judging by the SEMA picture, I would probably think that too; however their website clearly advertises them as high-performance braking systems and they have an application guide for anything from Mustangs to Subarus.

Jesus... Make sure you CC the NHTSB on that email to ZMI. :lol:
