I have two bootlids, one is plain, the other has the std R34 GTR wing on it. I only did a 6-8 laps at Winton with the rear spoiler and I dont think it makes much of a difference. When I get a chance I want to throw the wings and boot lids on a trailer and test one day at Winton...since I am moving to within a 45min drive of Winton for a project there are going to be plenty of Friday practices that I run down for

Uhuh. I have two boots as well, one with replica 32 GTR wing and Nismo lip, other with ARC alloy wing with adjustable gurney flap. ARC defs creates more rear downforce, but unbalanced it front to rear (I don't have a front splitter).

Suprisingly, adding the Nismo lip to the stock GTR wing made a noticable difference. Evidently creates a high pressure zone atop the boot lid.

Well, I have a front undertray, though its not on the car at the moment as it makes a wheel alignment a pain and I need to get the car aligned and the oil cooler installed properly as the panel beater all that time ago didnt have the time to mount it properly. Also makes it a pain to get to the brake air guides etc which I can now finally finish because the Stoptechs are on and never coming off

So when the boot lid goes on I will have the undertray on

I have an undertray/skid plate, it made a small improvement but no match for "big wing like Mig fighter jet" (Russian accent)

I hope to get the mojo to make a front splitter extension about 4/5 inches to actually get some front downforce, rather than just trying to minimise lift.

you want voltex wing big boy. bit expensive but heaps good white man magic.

either that or use the C-West GT wing II - Suzuka like what I sold berry for his R34 (in it's V1 guise). they make R34 bolt on version and it works bloody well.

Thanks for the heads up.

It would be good if I could put a leading edge lip on the front of my undertray. Will e easy to do, only problem is I drive my car daily so god knows the Cossie is a nightmare being only 50mm off the ground...dont want the R32 to be the same so would have to be removable for daily driving duties....the ideal solution I have is too expensive so wont go there :)

if you've got two boot lids, so who cares how many holes there are in one of them?

I'm sure expensive Voltex wings are very good, but my $300 CF China wing worked well enough to totally transfom my car from near uncontrolable oversteer to plough understeerer in back to back sessions on the same day not touching anything else on the car. While only costing ~3kph in top speed, but that was into a headwind that day... And it dented the hatch in on my 180SX. I went 7 tenths quicker than before on those tyres, while being very compromised by understeer. If you could balance that out with front aero, you'd easily make at least that much time again. probably more. If a $3000 Voltex wing works better, its only going to make your life more difficult to get enough front aero.

The gurney flap would make a difference. But a dual plane wing is technically a better solution. You need one of these...but woudl cost waaaaay more

But, truth is I dont pretend to know that much about aero. To me its all wank for 99% of us. We end up with ugly cars with parachutes attached...but there are a few basic concepts that seem best to follow

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
