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 :D

Please enlighten me

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

cheerio :D

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)

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!

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

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.

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.

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.

    • Ha ha ha, that's fair mate! We have the crackhead dogs now. Mainly because the missus wants the crazy dogs while she still has the energy and capacity to be able to keep up with them! Ha ha our current two are both Working GSD, there brothers and sisters (from the same litters) are in Police, Corrective Services, and I believe one did end up in defence force too. They're wild and fun, yet right now, both curled up asleep on the lounge room floor while we watch some TV. Mal is very likely the next dog (unless I get my couch potato guardian dog 😛 )   What are your Kitties names? Are you planning some house work, like those high kitty shelves, built in scratching post, and some cat passages from one room to another room?
    • Maine Coone, did look at but to big and fluffy As for performance dogs, we had Mals at work, performance dogs are fun to watch, but, way to much work for this old rooster
    • Yep, it was only an option on the Q50 Hybrid.  Same in Japan as far as I know. And doesn't use a centre diff like the Suby's do, so not the same as the WRX.  But it also isn't a reactive AWD like other Nissan AWD vehicles are, eg. Murano/Xtrail/etc.
    • You should have got a Maine Coone then. Only thing is they're big. But so cool, and just like a dog. Or, just get yourself a high performance dog. That'll teach you for wanting Parkour indoors 😛
    • Are you thinking of Bens R32? I don't remember if his went through the bonnet itself, but it went through the chassis rail. Brad (RISKIN) bought it, and turned it into a track car. It's funny how anti people are of Jim Berry now. I remember when I pulled mine out (during an engine change) and inspected it and found it cracking badly. At that point in time so many people were even on SAU, were so pro Jim Berry, and that was after Bens GTR exploded his quite publically.
