Someone Want To Tell Me About These Ducts...

[Ronin 09]

See the below pic, anyone have these on their GTR - the bit from the front lower lip to the wheel well...

Are they are factory part, or are they a Nismo part??

I don't have em, and want a pair

Please enlighten me

I figured that you could duct them to the brakes...

cheerio

[Noy]

i got them on my 33 gtr and thats what there for brake ducts, i'm pretty sure that they are a stock nissan item. maybe someone could get u a part number.

[Ronin 09]

i've not seen them on a 32?

I was actually looking at not having such a dramatic change in cross sectional area along the length of th educts...as i thought doing so may cause turbulence at the inlet and hurt flow...albeit it would increase the velocity of air...

No doubt Nissan no more then me. But looking at race cars, after having a large throat to capture air, they typically maintain a similar cross sectional area, even if they do go freom rectangular passage to 80mm flex duct.

My undertray also goes to just in front of the steering rack...if you want one should be a bolt on between GTST and GTR once i am sure the ducting works (LOL, bring on Sandown)

32 GTR ones are flat without ducts

My 89 has them. Looking at FAST suggests they are standard part for JDM spec R32 GTR's

I have them on my GTR....well i have one now! The other one ripped off as i had to drive somewhere without a front bar (cooler hose blew off and i was already 1hr late). I dont think the cable ties held it well enough. I was thinking of going proper ducting like V8 supercar style instead of using these. Otherwise i gotta find one more!

I should add that my car also has a curved rubber 'defelector' attached to each of the tension (castor) rods, which directs air from the ducts onto the back face of the brake disc through a hole in the backing plate. These also appear to be a standard JDM R32 GTR part.

I doubt that it's particularly effective, but better than nothing.

[Roy]

Rip off the backing plates and its something for nothing...lol i have spent way too much time looking at google pic search coming up with my budget brake upgrade that doesnt involve upgrading brakes

[Scooby]

my 32 GTR has them and it's a standard 32

[Topaz]

same my 32GTR has them, but I took them off recently, being brake ducts I might put them back on again

i think the intention here was to have them double as pie coolers. pie too hot? place in front of duct, drive for 2 minutes then remove. perfecto. the reduced cross sectional area stops said pie from entering brake rotor - messy.

hahah I give up I must be mad!

[N1GTR]

My gtr didnt have these when i got it, but thats an easy fix - im getting some made from aluminium

[t01-100]

My R32 V-Spec II has them, but I have only kept to the tow point of the factory part, cut the rest off, installed a PCV downpipe section to convert the 4"x1.5" duct into a round 3.5" duct and run heat tollerent flexi ducting back to the rotor centre.

The item on my car that isn't in that pic is an extra air guide on the castor rods... again, cut and shut the air guide and its now just a bracket that the ducting is braced to.

Looks like i'll have to check mine out, highly doubt if i have them.

[benm]

Yeah I have them..

Indeed i do but its not like i'm a sick racer liky Roy to use the benificial that it design for anyway.

[T04GTR]

standard issue 32 gtr brake cooling ducts.

they all have them.

if not they have been ripped of on a driveway or the like.

:lol: :lol: :lol:
