Happy New Year to everyone from South Africa

I have a 1972 Aussie Valiant Charger but I'm using a Mustang II spindle with coil overs

Saw these Helix Wavestop rotors: Mustang II Disc Brake Conversion 2-piece Spindle 11in Big Brake Conversion 5x4.5 | johnnylawmotors.com

I was wondering if anyone had used them or had any insight into them, weight etc
I think they use large GM single pot callipers - any ideas on how they work?

Thanks,

Brett

But are they any good?
Drilling is not really a great idea usually as it can lead to cracks.

Also curious how much they weigh
 
If they are advertised as 11 inch rotors, does that measurement include the scalloped area? If so when braking the brake pad would not even be in contact with the that part of the rotor, and if not part of it, then the pad does not come in contact with, more weight than necessary.
 
Well 50% of the time they could be 11s and the other 50% they could be 10.7s, lol
The big thing is;can they shed heat, or rather will they shed enough heat in your application?
If they can do that, then I'd try them. yeah, I'm stuck on cute,lol.
I'm a streeter, and I have my rear brake bias set very high to take advantage of the 295s back there. As a consequence, my KH 4piston front pads last a really really long time. So I guess, I'm not using a lot of front brake. Or at least most of the time they are just there ready to work. I have a stick car with 11/1 compression, so when I lift off the gas, my 367 is like a little Jake-Brake. So again, I don't use the brake much. Plus I'm 64 so I don't usually drive like a teenager anymore.
So, All in all, I could probably do with 9" drums 85% of the time. I think those little cute discs, could be suitable for my application.
Your ride may require more, only you will know for sure.
But/and/hyup; they sure look pretty.
 
Yeah I'm going efi Hemi 265 Turbo (+/- 450-500hp)
Streeter but it's going to be much much fun
Will get a rear disc setup with a TSD-500 helical gear diff but may have to go Wilwoods.
The issue is that I'm paying 13 times for the Dollar plus 40% import duty so trying to budget but get the most bang for my buckaroo!

Those Helix are cute but I think they might be pretty heavy and they only work with big GM single pots

Most have issues but if the have chamfers around the hole they are way less prone to crack
 
what is the point of the waves? so you either have the pads biting against an uneven braking surface, or you have extra disc material sticking out you aren't using. Either way I can't see any advantage.

@brewil if it will help you out on exchange/duties, I will gladly place/accept any orders for you here in Murrica and post them along as "prototype parts for testing". I have done it for many many Aussie friends as their dollar bounces constantly..

Sweet mate, I will definitely keep that in mind when I go to order.
 
Found this on a motorcycle website. There is a company called galfer that makes the wave rotors for motorcycles, in this explanation i could see where this would apply in the larger scale car rotors.


“So what's the big deal? Why upgrade to Wave Rotors? Galfer Wave Rotors utilize the entire brake pad surface to maximize stopping power. In testing their rotors & combined with Braided Lines, Galfer achieved stopping power 30% greater than stock disk designs.

How is that possible? When you grab a fistful of front brake, the moment of initial bite is when maximum grip is generated. However, the more you brake, the less grip your braking system will have. Galfer Wave Rotors focus exclusively on this moment of inital bite to generate brute force brake power.

The shape of the waves are engineered in such a way to enable the disc to provide constant new braking surface while the brake pad is trying to establish that bite as the disc is rotating!

Galfer Wave Rotors also offer improved heat dissipatation characteristics. As the disks heat up, your pads can lose their grip. This is because the heat generated from constant braking can glaze the pads. If the rotors heat up enough, they can burn off the pads (been there, done that!), or worse yet- expand the metal beyond its design tolerances. Equals warped rotors.

Galfer's rotors have a wave design that maximizes initial bite plus continues to provide a fresh bite of the disk as it rotates!”
 
I ran Galfers and the only diffrence I saw was increased pad wear. Also these Helix rotors are NOTHING like Galfers. These simply have a wave edge to them. These are gimmicky BS at best. One of the first things they point out is how cool they look...pass on these
 
If going with an after market rotor, I would look at Hawk Performance or PowerStop. I'm not sure what they offer in the Mustang II realm, but I have had great results with both

This explanation is not accurate. brakes fade when hot because the friction material off gasses as it heats up. The gas builds a layer between the rotor and the pads, causing no friction, no brakes. Drilled holes help to get rid of the off gasses....Different friction material withstand different heat ranges. Organic off gasses the soonest, fades first...
 
Speedway Motors sells a similar kit with standard Maverick 11" rotors and GM calipers. I have the kit installed on my 76 Mercury Bobcat.

Prefer these at 30% with CH2017 code so they're $517

Made in USA 4 piston floating discs

Why don't you see what is available from the used car wrecker.Most local cars have excellent 4 spot calipers ,even my old falcon ute has them standard.Try an find an old stub and match it up.My mate converted his challenger from Dodge to valiant and is useing standard brakes.I plan to keep the 340 Duster fronts as they are 4 pot but they don't float so not sure if i can change that or not as i've got other little jobs to do.Good luck
