Same here. When I searched for it to get the story behind the wheel, all I found was steelies. The guy found it in a shipping container he bought, so who knows where it came from. The warning sticker was in English, though, so not a JDM item.

Here's what is stamped on the back of the spokes:

ENKEI 5
JK00A
SK59
J DOT
NISSAN
17x4T
30
N05A-740

I hadn't even noticed the Enkei aspect until just now... Bonus!

It's 5x114.3 and 66.1mm hub bore. Adapter ring not really needed but WTH.

Edit: The tire is used on a lot of Nissan/Infiniti sport coupes, so maybe one of the high end models has the alloy as an upgraded element? Oh, and look at the RX-7 for another possibility. It supposedly has a 25 lb alloy; 135x7 I think.

Mine arnt drag skinnes but I have 205s on 2000 Solara alum. wheels on the front of my SC4. Im sure you could go 195. Also using this setup for the spare.

Here's another one I don't recall seeing mentioned: hood blanket/liner = 2 lb 2 oz with plastic fasteners. I was expecting half or less that amount, so that was a pleasant surprise.

I did my homework before removing it and found the expected answers: noise insulation, fire/heat suppressant. However, there appears to be little but snake oil salesmanship behind any of it. Safety responders report it making virtually no difference in suppressing engine fires (besides, I've yet to have one and don't plan to start now) -- the plastic tabs melt, allowing the fiberglass blanket to drop. Some say it helps protect the hood paint from damage due to engine heat, but many more say it makes no difference. (Some people cut out just the middle portion of the blanket and refasten it above the engine.) The people who do report problems seem to be those with the intake manifold off to the side and engine heat closer to the hood underside. And even noise insulation is hotly contested, with just as many people saying they couldn't tell a difference. I haven't driven it yet to see for myself, but even if it's louder, who cares? I want to hear the V8!

However, heat is definitely somewhat of an issue. The plastic clips above the engine all shattered upon removal, while the perimeter ones came out intact. The central ones were obviously cooked.

Found the info for it. That wheel is the spare for 07-09 Infinity G35's. They go for about $120-150 per wheel/tire. I wouldnt mind having 3 of them, 1 for a spare, and 2 for the track. Thanks for posting up the info

Glad to have helped. I also found it listed as being from a G37 in an expired eBay ad (cached Google image search), but that may have been inaccurate. The narrow range of use in just one car would explain why they're so hard to find anything on them.

I've got a set of Nissan-Toyota hub rings on order. As soon as those arrive I'll mount the spare and see if I can get some rough caliper clearance measurements. The spokes are pretty heavily curved, so I think they'll leave plenty of room. Yeah, I know I don't need the hub ring to do so, but I might as well confirm the fitment of everything at once.

As promised, here's a few pics of the Nissan spare. The 66.1-60.1mm hub ring fits perfect, and the spokes have lots of clearance for the stock SC400 front calipers. Quite likely enough for LS400 calipers, even. Maybe a small spacer would be needed, but only like 3-5mm I'm guessing.

The one thing I didn't like is the Toyota lug nuts are a bit iffy on it. The Nissan lug nuts must be a much narrower spline, because the holes in the wheel don't allow the Toyota ones to thread in more than halfway. The base of the nut presses the wheel in, which is probably sufficient for very limited use, but the lip and washer don't make contact.

t2d2, are the lug seats on the wheel conical by chance? Cause IIRC, the G35/37 use conical lugs unlike our factory shank style from Lexus/Toyota.

I would say worst case scenario, a set of Weld lug nuts may be a solution.

t2d2

iTrader: (8)

Yeah, they have a tapered lip to the seat, which I guess is conical? I have some aftermarket lug nuts from the wheels that came on the car. It might be worth seeing if they fit the holes better. They don't work great with the stock wheels, though, so I would have to carry a set of 5 with the spare, unless going to aftermarket wheels altogether.

Do Weld lug nuts work for both styles? I'm not familiar with them.

turbodremz

iTrader: (18)

They may be conical then, just hard to determine in the pics. Weld lugs are shank style lugs, but have a deeper seat. My Weld lugs for my Draglite wheels are almost 3" long, and threads on to the entire stud with the exception of 1/4" for torquing the wheel down. However, if the inner diameter of the lug seat on the spare isnt wide enough, the Weld lugs wont work, that and centering the Draglite wheels is not a simple task.

Edit: happened to be on the phone with a buddy of mine while typing this, and he has an 07 G35 with the same spare, and yes its a conical lug nut. So an aftermarket set of lugs may work just fine.

Convenient timing. I'll report back if I discover otherwise with my aftermarket lug nuts, in the unlikely event the holes are some funky size.

Here's another one, since I'm on a roll: rear tie-down hooks = 4 lb 4 oz (4 bolts left in for muffler mounts). I assume there's another 2+ lbs to be had with the front hook, but that's a bit more involved to get to. It's just the one on the pass. side, I think? Gotta squeeze back under the car to be sure... (Edit: Nope, there's one on each side. That's what I get for trusting the convoluted FSM!)

Byw. if anyone goes with my 2000 solara wheels, you need to grab the lug nuts while your at the salvage yard.

Lexan windows, flat panel bottom and diffuser going on. Had been running without door or rear glass for a while, but it was not good for aero, especially with the wing.

Picked up an 48"X96" UV Lexan sheet for $60, from Regal Plastics here in Houston. Need to get another sheet for the front windshield. I'm not sure how much the stock windows weigh as I broke them out with a air hammer. Guessing about 25-45lbs weight savings over glass.

Is it normally that cheap? I thought it was similar in price to plexiglass.

I saw an interesting suggestion in an RX-7 forum for cutting weight without sacrificing all of the related comforts: replace the moon roof glass with a CF panel. That way, you still have a functional sunroof. Of course, you could also replace it with lexan for perhaps comparable weight savings and still get the daylight with the roof closed. Hmm, that sort of makes me want to order a much needed new seal and cut/tint a lexan panel...

It probably depends on your location and plastic supplier. Home Depot sells 36"X72" sheets for $100. Sunroof is 35lbs.

t2d2

iTrader: (8)

Yeah, I looked on Home Depot and smaller sheets than yours were nearly double the cost.

35 lbs is for the whole sunroof assembly, I assume, not just the glass? I took my glass out this summer in an attempt to fill out the gasket/seal/weatherstrip to reduce wind noise, and I don't recall it being more than 10-15 lbs.

Another option is a Lexan insert minus the motor and track. That would get you as close to the weight of a sunroof delete as possible, while still having the daylight when you want it (which is all the time!).
