Even lighter rotors??

synolimit · 03-17-2014, 02:54 AM

Went to audi yesterday. I've seen a wave cut before on rotors but a new 2014 RS-5 got me thinking. Why not ask Z1 to cut the weight even more on their rotor by doing a wave patten? Less weight doesn't offset the less material loss or something?

I think the wave cut requires additional manufacturing processes which may increase their price over round rotors. From what I've read on Audi's as well, it was a solution to increases their resistance to warping more than a weight saving thing.

Wonder what the cost vs savings lbs vs less material means fast heat up time is.

Why does it look like it's wavy on the outter face and still a full round rotor on the inner face? That's definitely not the shield.

Ceramic brake rotor are the lightest.

It is the heatshield, I've seen it on a coworkers RS5.

Looks like the shield.

Why not just shave the rotors down if you really want to save weight?

For a machinest to do one set it'd be a lot. Cheaper for someone like Z1 to order like 100 pairs at whatever cost over the original.

Can't see people ordering 100 sets of rotors that don't last as long or cost a few hundred extra dollars.

And if they can turn your brakes for $10, just have them turn them like 5 times, lol.

Wilwood High-Performance Disc Brakes - Hat (Bell) Mount Rotors

Willwood has a few, they call them scalloped rotors that are not safe for street use and mainly used for midget. The biggest they have are 12 in and might be able to be used with the hats for their kits for our cars. But doesn't hurt to call and ask if they would fit the akebonos.

If you have thinner rotors then the pistons in the calipers will have to extend further to push the pads into the rotors. This will make the pedal feel soft.

Yeah, but if we're really trying to save 1lb here and there at whatever expense, I think shaving the rotors is just as viable of an option. I still think its a little bit out there of an idea, and not worth it.

The other thing, if rotors are not CAST with holes or in roughly the same shape as the final shape, the rotors will be week. Z1 and every other company making rotors gets a bad rap because CUSTOMERS order drilled rotors, I doubt they want to deal with the crap PR of having a BUNCH of scalloped rotors cracking to hell.

This would be a neat option to have but it would be more cost effective to go with the Z1 rotor upgrade rather than paying a few hundo more for a pound or two.
