    Brake Duct Mod

    Little jacking around at a shop





    You will need to pop a couple of holes in the plastic to get a zip tie through and mount it to something on the car. If you don't it will just come off.

    Never dynoed with it but the idea was to direct the flow of air right into a modded stock box.

    Re: Brake Duct Mod

    I was wondering if anyone was going to try this. Looks like good work. Of course, the next question is how badly do our front brakes need cooling ducts? Would also be interesting to see this sort of mod with a cold air intake system.

    Judging by the fact that I warped my front rotors at a track day, I would say that the ducting to the front brakes is already inadequate.

    I am with AZ Star, I haven't warped a rotor, but I did overheat a pad, and it shredded which put me metal on metal with the pad backing and rotor. That hooked me into a spin and through a muddy infield. Cost for one rotor - $240.00.

    If anything we need more air on the brakes. I also have had some serious hot spots on the rear rotors and think we need some vents for the rear brakes.

    I was thinking the front duct would get a mod to "open up" the duct a little more, taking some of that diffuser area underneath the duct as where to "scoop" more air. The rear I was thinking I could design a duct but I have since found it hard to find a spot to attach it to the undercarriage.

    I can tell you this putting a high powered fan 20-30mph on that duct will get massive air up into the box. Higher speeds will be insane.

    Re: Brake Duct Mod

    I'm not getting the heat issues from trail braking, rather from the track we run. Eagles Canyon is notoriously tough on brakes due to the long straights into double apex corners, and then long straights again.

    I would like to modify a road course rear brake funnel to the car, but like Silver Bullit mentions, there are no great outboard mounting points.

    We also need to remember, this isn't a track dedicated car, but it is a great street car that happens to run well on a track. These just happen to be issues we face with most large heavy sedans that try to double as road course machines. I try to remind myself, this is still a Cadillac 6 days a week, and on the weekend, it is a Porsche/Corvette chaser - BMW beater.

    Maybe try taking some of the brake ductwork off a V1 and making it fit into a V2? Just a thought.

    Re: Brake Duct Mod

    Heeyyyyy where's my credit ? I invented the brake mod for the v =) everyone was telling me that they didnt want to kill airflow to their brakes and now i see everyone pulling it apart. But it does make a huge difference, I got the idea from my jeep srt8 as it had similar front air routing to the calipers. Ideally though what we need is an abs intake pipe (wait4me in the works ) w/ a heat shield of sorts and pulling the brake duct. That will force a ridiculous amount of air into the intake.

    Cooler air to the intake is always best. But IMO it's not possible to achieve increased airbox pressure, even if all four brake ducts were used. The system is a massive vacuume. Removing restrictions is most improtant.

    Exactly. That's what our superchargers are for.
