From my research the yellow top ones (forget the brand) and braille batteries are both very good compared to stock, but the down side is you cannot let them sit for very long or they just die. I think for the braille battery I was looking at 3 days tops, but you can just throw on a trickle charger if you plan on being gone for a long period and be fine also.

I agree with Dreamer. The best lightweight ones are braille. The best is the B3121 if you're worried about leaving it out too long or worried it will go dead. It only weighs 21 pounds, which is still good, especially if you're relocating the battery to the back, which improves weight distribution. The other 15 pound batteries are good too, it just depends on your preferences

Odyssey is the same as braille and much cheaper.

Will have to look into Odyssey.
I was about to jump on a braille battery with trickle charge kit just in case, but same quality and better price is always a plus.

Odyssey Light Weight Battery PC680: 14lbs (6.35kg) | Reduction: 21lbs (9.53kg)

NewYorkJon34 · 01-14-2011, 10:00 PM

Which one would be best for street use? I want it to be reliable

RCZ · 01-15-2011, 11:32 AM

The PC680, I've seen people use it for years without issues...

Anyway, so I'm starting to get into taking weight off the car....just wondering what everyone is doing, has done or is thinking about doing to take weight off without making big sacrifices.

I know I can get rid of my interior, but thats not realistic. I'm looking for things that we can all do with some slight modifications. Getting rid of things we dont need, inexpensive part swaps, etc.

I'll throw in the first one:

You can very easily remove 5lbs off the car by removing the hatch weight. All you have to do is pull down the plastic from the hatch and look around the middle, there is a big black square weight held in with like 6 screws. I guess its to make the hatch more weight-neutral when swinging it down and up. Completely pointless. Take it out...go faster.

I had thought about stripping the interior to remove the sound damping and then replacing the interior, but that's a lot of work for just 20-30 pounds.

theDreamer · 01-15-2011, 01:28 PM

My weight reduction goals for 2011:
-Battery
-Seats
-Rear hatch area

NYBladeZ · 01-16-2011, 01:29 AM

I've gone a pretty unconventional route to reduce weight. While I've never taken the trouble to actually weigh in after replacing almost every panel with carbon fiber I can confidentially say the car feels much lighter. The Nissan tech in Smithtown said you can feel it once you let off the clutch. I'm shooting for a set of race sets in 2011 and a seibon hatch (last missing panel) on which I'll put a Kognition wing. Down the line I'm shooting for some ultra light wheels.

RCZ · 01-16-2011, 03:25 PM

you know...the panels on the car are not that heavy, I'd be interested to see how much weight you actually shed. Can you post a couple pictures on here of what your car looks like now NYbladeZ?

NYBladeZ · 01-17-2011, 12:35 AM

I know they aren't that heavy but upon removing the and carrying them around, the carbon fiber pieces were always lighter. Add to it that I was fully sponsored for a lot of the pieces I ended up with a one of a kind car. I will say this, if I knew I'd take it this route I wouldn't have gone red, and although I kinda like the red rear quarters and roof when its all said and done, I'll probably get flat black overlays when its all said and done. I'll post pics soon.

NYBladeZ · 01-17-2011, 12:38 AM

Just a few other things, I've installed a braille battery which is a very noticable difference! I've also removed everything in the rear, spare, jack and everything else back there. Warning, if you do remove everything you will get light in the rear and it will be more figgity. Thankfully the wife gave me the green light to get M. Bonnani's Kognition Wing that was for sale on here. That should create more than enough downforce, and hopefully coilovers to follow.

Other than carbon shell seats and amt wheels I can't think of any other weight savings short of stripping the interior and hammering out the sound deafening.

NewYorkJon34 · 01-17-2011, 09:30 AM

Which Braille battery did you install? Has it been fine for your daily driven use?

Endgame · 01-17-2011, 11:02 AM

i have the same question about the battery..... is it ok if the Z only gets driven 2 times a week?
