Post pictures of your brake duct

I'm planning to hit the track more often next year, and looking for brake duct options, please post pictures of your brake duct and a brief review, Thanks :)

Thanks Ken

I just got my NSX less than 2 months ago, it's a blast to drive. I also signed up for the NSXCA membership last week. I had big brake kit On my previous car (2001 Audi S4) and I've also read about all the debate regarding BBK or stock brakes in this forum, so I wanna give the stock brakes a try.
Would you recommend dali's brake duct? is there other options?

Thanks

Dali offers two options. One is a deflector, which replaces the stock deflector with a wider one. It's inexpensive, can't hurt anything, and probably helps a little, but not as much as true ducting. I think it's worth trying before you go to anything more radical. The other is an actual ducting kit, which is pricy and which requires the removal of the air conditioning; I'm sure that one helps a lot, but obviously, it's not for everyone.

Yes, you can always get high-temp ducting (available from online race shops) and have a custom install; it's not that difficult for a shop with race prep experience. If you're willing to live with two-inch ducting, you can squeeze it alongsize the bottom corners of the radiator, and you won't have to remove anything or have it reduce ground clearance. They cut two-inch holes in my splash shields, welded a flange to them, and used that as a mounting surface for the hub end of the ducting.
 
My techie made a custom ducting with aluminium plates from the holes where the foglights used to be (A/C is removed) - reduced the top disc temperatures appr. by 150 degrees Celsius (now never more than 450 degrees).

Downside: With the holes completely open I experienced more understeer than before in high speed corners (over 100 mph). I guess I lost a bit downforce. Ended up with closing the holes by 50% - still enough cooling, but more downforce. Looks like that:

post your brake duct pics.

Ken and All….THANKS for the info.

I, like Polor, am looking for more detailed pictures of ducting, hoses, mounting brackets, custom ducting, etc. We are all aware of the great improvement in braking that comes with substantial brake cooling and increased airflow

What would be really appreciated is photos shot from underneath and from inside the wheel wells. Guys with race prepped or track type X’s PLEASE help out here. Now seems to be a perfect time to do some brake mods.

DAVE
 
I like the carbon one!!! But as you know we can't have the same items anyway! The RM one is $100 cheaper and lower, and will give more downforce. I will admit I like the look of the Dali one better, cause I am a sucker for c/f. But as low as the NSX is, you may end up painting the c/f black as Kevin had to do to cover all of the battle scars!
 
I already plan on having it painted Black...considering the WW Side Skirts and rear 03 Valence should look good with the Gun Metal Volk GTCs. :D

Just FOOLIN around with ya.... I know you can take a little ribbin. The Marga Hills is TOO much I like the WW I think it's just the right size Skirt. The Spoiler looks like it has the perfect air channel for a small duct to the Brakes.



Peace Bro!!!

I thought that the plastic one from RM was not track worthy because it flexes quite a bit. Hopefully you have the track version of the splitter..

The correct ducting would be to the center of the rotor (hat).

Hmmmmm, got me thinking.

I just went to the laundry room and looked at my old Eureka vaccum extension attachments and I think I may have found a simpleton solution here.

The black flexible extension tubeing is 5' long without stretching so that should be ample ducting. One solid end (the one that fits into other solid extensions) looks identical to the one that goes into the rotor - it is only 1 1/8" wide so it could fit one of the two brake shield holes for those who have the brake shield.

I will paly with this idea once I have it on a lift. Whether this tubing will be able to sustain the heat from the track or the environmental conditions it's a different story but then what do you expect from household scarp ;)

52 weeks in a year, 26 w/o the kids, 1/2 for the wife, that leaves 13 weekends for the track! :D At least I am not afraid to go to the track in the rain or snow, and actually DO the events! Steve the season starts in 3 months @ Gingerman rain/sleet/snow or shine.

I am holding off on the supports. I think it will be fine, since track speeds are less than what Sean does on the street, and his holds up fine. If it does wobble, I will get the supports.

You can get some here to.

If any of you looked at my car at xpo you would,ve seen a simple effective diy brake duct solution.We cut mobil oil plastic container in half and used the half with the mouth(top) turned backward,and to this we zip tied a length of lowes brand pcv( blue) tubbing used for pools.This fits on the mouth of the oil can well.The tubing is zip tied to the susp and the end is tied to a dali deflecter.We also removed the slotted plastic front inner wheel well liner that now exposes those small fans.I have the heat shields removed.When I tested rotor temps with the ducts blocked vs open the difference was 125 deg f.I also put a mesh screen in front of the air collecters(oil cans).I know you want pics well I'm not too good at that.When I get a chance (could be months) I'll take some and e-mail them to Lud.
