370Z weigh 1499 Kg with a full tank of gas?

According to the owners manual the 370z holds 19gal of unleaded gasoline.

According to imperial measurments gasoline weighs between 5.9 and 6.5lb/gal depending on the fuel mixture.

According to math (using an average weight of 6.2lb/gal for gasoline) a full tank of gas on the 370z would weigh 117.8lbs....

When I autox a car I run at 1/4tank of fuel, no spare, no jack, removed floormats. Based on the above information in this thread we can assume that a B Stock SCCA Solo II 370z would weigh:

Stock (full tank of gas): 3,342lbs
minus 3/4 tank of gas: 88lbs
minus spare (conservative): 30lbs
minus jack/floormats: 5lbs
TOTAL: 3,219lbs

This doesn't even take into account the fact you can run lighters wheels/tires (20-30lbs here), hollow front anti-roll bar (2-3lbs here), and a lighter weight exhaust (prepare to loose around 30-40lbs here).

I think it's safe to say that a B Stock SOLO II car can be under 3,200lbs race ready.

I think 3340ish is about right, as the reviewers have claimed.

This is with a full take of gas.

Since the Bose sub is located inside the actual spare, does anyone know if we will be able to remove all the spare tire junk while still keeping the speaker there and vibration-free?

Not a concern of mine. Base 370z + Sports package for me

WHEEL WEIGHTS:

I did some checking and indeed the factory Rays are claimed to be VERY VERY light. Speculation is in the range of 20% lighter than the NISMO wheels that were on the 2007 NISMO. That's simply incredible. Without spending a fortune on wheels (or going to a smaller diameter which is not legal in the B Stock class that I'm talking about), you'd be hard pressed to drop more than 1lb per corner from wheel weight. I found the Enki RP03 in factory sizes that will be about 1lb/wheel lighter for about $380/wheel. If you want to drop a significant ammount of weight (3-4lbs) per wheel then you would need to go with some custom forgline or ccw wheels ($1500~/wheel).

Personally I will be using the stock wheels for autox (with Hoosiers on them), and a set of custom wheels for the street (with Toyo T1S's on them) because the stock wheels are just so damn light.
