Hey guys,

Since ordering my car, I'm thinking already about mods...I know, its a sickness. Since not to many power mods will be out yet for the VQ37, I'm thinking about taking out some weight, w/o runing the car. I'd like to get a lightweight battery, say 10lbs total vs. the stock 50ish pounds (anyone every weighted a G battery) and maybe take out the spare tire/jack kit and replace it with fix a flat.

75lbs is pretty significant and unlike a power mod, its good for braking and handling too. Am i crazy? LOL.

How about lightweight exhausts. Anyone got any suggestions?

Good start bro

nahh you're not crazy!

weight reduction = better acceleration and better braking

there was a quote somewhere that said just that....its at the tip of my tongue but i can't recalll

 

Mike S, hummm you wouldn't happen to be the Mike that had a 3rd Gen Max, then I believe an SE-R are you? Probably not, but thought I would ask.

and I think you were from around Buffalo

 

GEE35X,

Well yes I am! I had my 93 Maxima, then I leased an 06 Altima SE-R. Now that car is due up in a few months. How do I know you? I did go to a Maxima meet one time in the GTA. I'm in Buffalo, NY.

 

LOL, I had a 94 red Max then a 02 Ivory Pearl Max SE. I belonged to the 3rd gen board, TMEC site, Max org and the SE-R board. On those boards I went by Max or Frankie.

 

Right on. I think I remember the name Frankie. I was way into modding my 93 (but I didn't have the $$$), but my SE-R...lol...I haven't even changed a light bulb. That thing is bone stock..well...except my winter tires/rims.

I'm looking forward to adding a bit of power to the G37 (6sp btw ), taking off some weight and maybe a few other things, but nothing crazy.

 

Well, welcome to the site and congratulations on your G37 Sedan

 

Yes, I think you're crazy. You're worried about weight reduction in a luxury mid-size car. If performance is high enough on your priority list to do weight reduction modifications, you should have chose a different type of vehicle.

 

^^ it's still a Skyline...

 

There is nothing wrong about putting the car on diet. Its not like he is talking about removing the backseats, etc.... Simple and non noticable weight reduction is always a good thing...

 

You'd save a lot more weight if you picked up a 370Z.

 

Update...so I did some fooling around this afternoon.

Number 1: My current ride (06 Altima SE-R)..so...VQ35DE, engine battery came in at 38.6 lbs. I'd assume a stock battery in a G35/37 to be around the same weight. Guess I was hoping the battery would weight more..so the savings would be more. Even still, a 10lb Braile batery would mean almost a 30lbs saving.

Number 2: Spare tire (T155/80 17) from my car came in at 40.6lbs! According to the 09 G37 brochure, the G has a 145/80 17in spare...so I'd assume it weights almost the same.

Others: jack/crowbar - 5lbs. Trunk mat - 5lbs. The trunk mat is the nice mat that is already on top of the standard trunk liner.

So....swapping battery and spare out and replacing the spare with a can of fix a flat and my emergency kit (which includes an air pump) should net me...


-30lbs for new battery
-40lbs for no spare
-5lbs for jack
-5lbs for trunk mat
+5 for fix a flat and emergyency kit
=75lbs!

 

- Stillen exhaust system (13lb's less than stock) / or titanium option
- Take off the shield under the hood
- Lighter wheels/tires (less rotational mass too)
- carbon fiber hood
- Take off the emblems...

 

Mike that is good drop in the weight but for regular street driving you probably won't notice that much. On a track or strip it would definitely help.

Another way is to replace yor wheels with a lighter forged set. You would also be surprised at weights of tires in the same size, but different manufacturers.
But as I said driving on the street your weight savings would probably be hardly noticeable.

Have fun with it.

 

The other thing to consider is where you are removing the weight from.
You will change the balance of the car as weight is removed.
