Is the 370Z a very light car?

I don't see how you came to that conclusion. Even changing the stuff you mentioned would not shave 500 pounds, which would be s2000 weight. If that were true we could easily get the car down to 2400 pounds gutted, which is just not going to happen.

There is definitely a good bit of weight to be lost on these cars, but lets keep it realistic. We gutted the entire car and have not saved 500 pounds. Weight does not come off nearly as easy as you first think it does

Ryan, have you guys done a weight with a fully stripped car?

Ryan@Forged · 07-29-2009, 12:42 PM

Still working on stripping the last bits. When we had everything minus the sound deadening and the dash out it weighed 3009 pounds. We have since removed the AC, sound deadening, and dash. The wheels, brakes, and exhaust have also been removed, but new ones have not gone on as of yet. I imagine we are still about 2 weeks away from it going back on the scales, but we will have to see. At that point we will have a better idea of what a fully stripped 370 weighs in at. My guess would be around 2825-2875.

What are the expectations of weight added from putting things back in? Or should I ask do you guys have a goal for an ideal weight?

I'm not going to gut out my car, but here are a few things that I have planned.

Forged wheels + racing buckets + no spare tire or tools + ti exhaust = about 150-200lbs of savings.
Does that sound about right?

Ryan@Forged · 07-29-2009, 02:19 PM

I would be surprised to see that much savings. A good bit of it depends specifically on which wheels, seats, and exhaust you get. Different manufactures have different weights. 150-200 is much more than it sounds. With the correct parts you might be able to get close to 150, but it would be a stretch.

Remember that we only saved a little over 300 pounds by gutting the car and removing the exhaust. This was with no seats as well.

theDreamer · 07-29-2009, 02:21 PM

^Yep, you can take things out but something is going to replace it and add some weight back.
Wheels - probably will save 3-4 pounds each (16 total)
Seats - probably 20 pounds
Spare plus tools - About 50 pounds
Ti exhaust - probably takes off another 45 pounds
So you save a total of 131 about, you might get even less with seats depending on which you go with.

Organik · 07-29-2009, 02:32 PM

^
So by that logic, if I can shave 20lbs off of my gut (which I could use.). I can realistically reach 150lbs of weight savings.
But really, how much does 150lbs matter in the 1/4 mile or even a curved track? Not that much I imagine.

Weight is more about balancing the car, not just about removing it. You can take out the 150lbs but you have to make sure the car is balanced for what you plan to do with it.

Exactly

Keep in mind around the corners (time attack/road racing) weight is significant. Dropping weight improves your acceleration, braking, and cornering. In time attack/road racing last year I edged out one of the cometitors by .02 seconds. Imagine if I added 150 pounds to the car. Think I still would have beat him? 150 pounds is pretty significant in competition IMO.

Organik · 07-29-2009, 02:43 PM

Ah, than I'm taking most of the weight off of the mid to back end of the car. How can I shave weight off of the front? Other than and aluminum flywheel, are there any other solutions?
I don't plan on racing, though I do plan on taking it through windy backroads at terrifying speeds.

Even weight distribution might be a good idea in that case.

with new safety laws there is no such thing as a light car. Unless the manufacturer wants to go the composite route you can kiss NEW light cars goodbye
