Wouldn't do it on my E90...but the ducting allows me to run the Stoptech Street pads in cooler temps on my E46. They keep the pads temps in a reasonable range that prevents them from transforming into a useless brick of pad material. I wouldn't even think about it without the ducts. If you route the ducts carefully, you can go lock to lock without tearing up the hoses. If you do wear a hole in the hose...just fix it with some duct tape. I think DDing with brake ducts is doable. I might be concerned about rain...probably not an issue especially if the brakes are warm/hot.

is the help with pad life pretty significant? that alone would make it worth getting some ducting setup. i haven't had any problems at the track. the brakes stay consistent when hot, but if i could get better performance and longer pad life, thats a win-win.

That's all I was pointing out. I do understand that mods give a person more confidence and can make that person drive better. It's a continuous black hole and we have an addict thread for that lols. But at the same time I see dudes who never tracked before with full aero packages talking about how they can feel the downforce working on turn x failing to realize a stock car could have handled that turn easily at those speeds. I get it though - people have their own preferences and mine is just that - a preference and opinion. But you know what people hammered into me when I was starting out or when looking to the fastest drivers along this path - maximize the car and your skill. And that's stuck with me. But to each their own. The smoking brakes wasn't an achievement to call out it rather that it can and does happen. But I'll be damned if I was the guy who needed it because I was coasting on brakes too much or just over braking in general. That's what I learned from being on this forum.

I'm getting about 5 weekends on a set of front pads in my E46. If I had to guess, I think I can get 6-7 with the ducting. Quote:
Threshold braking is important for a beginner. What drives me nuts is hopping into an advanced student's car and they still just hammer away at the brakes into every damned turn. That just tells me that they don't get it. A really good driver will drive just as fast a lap using up less brakes, tires, and fuel. The simple fact is...brakes never make the car go faster. So braking harder and harder just makes the car go slower and slower because the car is no longer maximizing traction at all 4 corners. I guess you can go buy better coilovers with stiffer springs and a $4000+ 2 way diff which will make the car better. A much easier way is to find ways to maintain momentum through the turn and get back to the throttle sooner.

Thanks, I might have my fab guy build some custom backing plates that fit inside of the rotors.
One thing that comes to mind is if the rotors are better off without backing plates... like instead of the entire rotor being exposed, it would now only be fed air through the ducts. Is less air (but more focused) as efficient as more air all over the place?

Porsche GT3 front duct. Simple and probably effective. Can't be that hard to make.

^ thats one of the things i had in mind. i love that porsche already proved the concept.
my fab guy could make something similar very easily with aluminum. the only downside i see would be if the scoops are aggressive, they would completely water blast the rotors in the rain. making them removable shouldn't be a big deal though.

Main problem I see wkthgetting the Porsche part to work is our control arm is a lot twistier
But at $20 a pop per side or thereabouts I still think I'm going to try it one of these days. |

More apex/exit speed = the same problem you had before but even worse because k=1/2mv^2 and you spent less time cooling off because you spent less time on the straight. Easy to make a car turn a fast lap, not so easy to make one turn 50 in a row at night in the rain flat out
That speed-energy correlation is why when people who are good, experienced drivers who can get the best apex/exit speeds out of a car drive these cars on track one of the the first things they bitch about when they come in after a session is the brakes, they give you really high hopes with their street performance because honestly it might be the best brake system outside of a Porsche anywhere especially in software and how it tolerates oh shit moments/low grip/odd tire sizes and just works. Amazingly capable system that can only reach its potential for a handful of laps before it shits the bed. Gives me the sads. Last edited by Richbot; 11-05-2016 at 09:55 AM.. |

I'll have him build custom scoops from aluminum. Maybe secure it to the oem shield.

Yikes don't do that the knuckle moves independent from the control arm or are you saying just hang something off the stock splash guard?
This is making me want to buy a 3D printer Fave setup I have seen is the c5 Vette part it's like a flattened ABS plastic tube that turns inward toward the rotor hat by where the Luca mounts and then picks up air from up front and the flattened part of the tube doesn't eat tire/steering lock clearance Last edited by Richbot; 11-05-2016 at 10:00 AM.. |

I'm talking about the dust shield. I'm just thinking out loud. Gotta get under the car and turn the wheel and see where we have room.

Pics please! And do you have a part number on the GT4 splitter?

I'll see if I can find pics.
But I've had 4 GT4 lips. I've had the mode carbon, the volkommen (plus a backup), the one banned member Meza01 was selling and an ebay one. They will eventually break/crack so don't waste $$ on the RKP or motorsport part. It doesn't affix to the chassis so the splitter can really only be as stiff as the factory mounting points. The volkommen was FRP so it was by far the most robust. It was heavy though. |
