I was planning to put a huge carbon GT-wing (as well as hood) on the back of a R34 GTR like this one from Jetspeed:

Mainly for cosmetic reasons as I think the JGTC look >>> tame stock spoiler (I know many people may not agree with me - this is just my taste).

Is it true it is defectable due to impairing rear vision?? Also heard of things like defected due to sharp edges eg., the sharp metal alloy ones and defected due to no replacement for the independent braking light on the spoiler itself (not an issue on the GTR).

Any advice would be greatly appreciated. Don't want to spend $$$ on a spoiler to have it go to waste.

Cheers

Not sure on vision impairment but I am sure I read somewhere about a wing protruding from the width of the car could be. E.g if the sides of it are further out than the guards. Not sure if that was in Oz though.

yeah pretty sure they are defectable.

Vicroads didnt allow me to register the car with the wing (came from japan with the wing)

Had to even remove the gt brackets off the bootlid as they can cause harm to someone rolling over my car?

Although i dont think the person flying over my car will be concerned about 2 small gt brackets lol

Technically all alloy bull bars are illegal on toyota's etc for the same reason. Factory plastic bumpers on modern cars are a little more forgiving than solid alloy or steel. Yet i've never seen a 4wd defected because it had an aftermarket bull bar on it.

If its not OEM its technically not legal to fit it unless you get an engineer to over-rule it. Yes that means everything from exhaust systems to brake rotors. Even if its ADR approved, if its not OEM factory fitted (or a factory optional) equipment its not legal unless approved by an engineer.

ADR just makes it easier to get the engineering approvals done.

Oh ok cool. Are GT wings easy to replace back and forth with the stock spoiler? As in just removing some screws? If it is, I might get it.

Seriously, I never thought about people rolling over my car and getting sliced up by the wing, and with a soft carbon wing I don't think it would do any more damage than the stock spoiler. I can't imagine how rolling people would fare over the spikes of the roof-mounted vortex generators on the Evo 9 then :blush:

gt wings are connected onto brackets on the boot lid. Held on by a couple of screws.

Problem with gt wings are that you will need to create 12~ holes in the bootlid..

Right, I see about the mounting brackets.

Does that mean if you want to go back from a GT wing to normal spoiler you will have extra holes left in your boot?

haha ofcourse, 12 nice holes in the bootlid, not to mention the other 3 from the original spoiler.

Only option would be to replace bootlid, as the holes are too close to each other to weld. Will warp the bootlid.

Ive got a spare bootlid sitting in the garage waiting to be painted :thumbsup:

The other option you have is to add something like the night-pager extention to the standard wing. This will raise the height of the stock wing and give it a slightly more subtle GT look but not cause any issues as far as defects go. I have one and I think its tops. You can get them from Nengun but the link to them can be found here:

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
