Wilwood Aero 6 Brake Kit at Hammer Performance

I put around 5K miles on this kit on my Gen 1, and it was a great improvement, will be doing to my Gen 3 as well….

I done reading on this. Structural straight is fine. But the drilling of the holes cause micro fractures. Some expensive for foreign cars cast the holes in the rotors which help. Beveling of the holes also has provided some help. Still an issue. Interesting to me.

Yeah I was gonna say that if you cast the rotor with the holes, they are less prone to cracking. Drilling them, as you said, introduces micro cracks that if only really street drive, cause little issue - it's at the track where the issues become big bad and ugly.

Likely a big difference in dimpled (cast) versus drilled. The DBA rings on my bench were for my ZL1 1LE. These are dimpled. BTW, this is what your garage becomes when you road race. You wait for rotors to go on sale in the winter and then buy 6 at a time. Terrible disease (road racing). I can quit whenever I want (is what I’ve been saying for 20 years). LOL

could you shoot me pricing on this kit as well?

thanks

I’m no metallurgist (physical or chemical), but I find it impossible to believe that introducing a hole into an engineered piece of steel somehow makes it more reliable or stronger. Some engineer spent time designing that casting, forging it, testing it……..and then someone else just drilled a bunch of holes in it? Just my $.02

Just because you find it impossible does not make it not true. I am not a physical or chemical metallurgist and i don't know a single one who tracks cars but none of them buy drilled rotors. Drilled rotors are marketed for looks and "Performance by allowing water an gasses to escape for better braking" Nascar, F1, IMSA, Michelin Pilot Challenge, Porsche Cup, Lamborghini Super Trofeo etc etc etc DO NOT USE the superior drilled rotors designed by engineers, they are either solid or slotted/hashed . I cannot tell you the number of drilled rotors i see on track weekends which have spider cracks STARTING from the holes. Hell I have had it happen to my OEM rotors before I switched to Slotted. Sure you see countless OEM drilled rotors from many High end manufactures (AMG, ///M, Porsche etc) STREET CARS but NOT on track cars.

The drilled holes will NOT cause any issues or be the source of stress cracks for your everyday hey look at my drilled rotors. Most drivers NEVER push a brakeing system even close to its stopping potential or max capablitites. Just becasue the Drilled Rotors may be fine for going to the grocery store does not mean the drilled is OK for ACTUAL Brake safety and performance.

Thank goodness this thread got resurrected……..LOL

And yes my belief does not make it true, but already tested and proven that dimpled, drilled or slotted rotors will not make your Ford Raptor Truck stop more quickly or shorter.

Dimpled, drilled or slotting rotors is used to help remove hot gases from the rotor surfaces during severe and extreme use cases. If you are running standard DOT brake fluid and have not boiled your brake fluid, you do not need to run anything other than a smooth brake rotor.
