Weight Reduction

justin_boy

Hey guys,
I'm working on stripping some weight from the z and wondering if any of you guys have weighed your z's and what your'e weighing in at against whp

i have 317 to the wheel and installing some parts hoping to get it up in the 330's, and hoping to come in around 3,000 with a full tank of gas, is that possible without really gutting it?

google search says approx 3250 but z1 motorsports said in a video they come stock around 3400-3450 depending on options

i have not weighed mine yet and was waiting until i had seats/rollcage put in

thank you!

btw searched the forum and all i found was the OG thread from 09'

cv129

Mine is about 3600 ish with 150lbs driver, all fluids, maybe a 1/2 or 1/4 tank gas. 09 Nismo OEM manual cloth seats. Spare donut was in the trunk. 3400 range sounds about right.

dang makes sense, was hoping it was a little lighter

3250 is not happening without gutting the car. That is not realistic to expect otherwise.

i think i knew that i just needed to hear it

justin_boy

i know that now lol

A bunch of people posted their corner weights in this thread. I was at 3450 with the rear hatch gutted and a full tank and me in the car.

A lot of the weight also would also have to come from the rear of the car, making the 53/47 weight distribution even worse.

3000 lbs requires gutting the car.

hmm good point, didn't even think about the distribution

I would agree if the car will stay without aero, with a wing, the weight distribution will not matter unless it is in Autocross or very slow circuit, without aero in a fast circuit, it is going to snap oversteer easily.

And I agree, 3000lbs needs major works, mine is at 1460 kg without driver, I think half tank of gas, removed spare and tools, many other bits, but with both seats installed, I assume it will come down to 1440 with racing seat and without passenger seat, I did it but didn't weight it

So, 3200 lbs WITHOUT PASSENGER could be possible with some efforts but no major work.

I've got my rear end completely gutted with fixed-back race seats. I'm hovering right around 3300-3400. So damn heavy! With that said, I've just recently replaced my coolant overflow resevoir with a much smaller one and removed the washer fluid tank. Lastly, I replaced the front bash bar for a custom lightweight tube for future FI clearance and weight reduction.

I'm curious what other people have done to lose some weight in the front, I feel like my car is now front-end heavy with all the gutting I've done in the rear.

gutted car here, with no headlights, a half cage, and everything superfluous removed. All track items needed (surge, baffled oil pan, etc) done, and car weighs 3010 lbs wet on the scale at my home track.

oh wow...thanks for that, that really helps me out. any pics?

victorofhavoc

Unfortunately not many decent photos yet. I bought the car mostly built from another member. I'm working on a splitter and detailing it out with photos in another thread in this same forum. Once that's done I'm going to de-livery the rest of it and then get some better photos. Hopefully I'll get some out on track soon .

I do expect the splitter setup to add about 25 pounds. I believe there's about 15 pounds of hardware I have in total right now for a rigid support and the carbon splitter should be around ten pounds I'm guessing. Cutting some big louvres into the hood would definitely reduce weight though
