I have weighed everything that has been removed and everything that has been added. I cannot address the weight savings for the MA Shaw GT2 wing as it was on when I purchased the car. when I find the time and my list, I will post all the weights. I am in agreement with Dez-- I do not understand the discrepancy.

I was weighed on corner banance scales at 339++ without the subwoofer which I think weighs about 12 pounds. I weighed the car again at Roebling Road and it was 3396 without the sub. Can't attest to the amount of fuel. My guage has been a bit whacky since the mods. I ran out of fuel at Roebling with the computer showing 72 miles remaining.

To settle the issue, we both need to fill the tank completely and go Neil's shop and weigh one after the other.

 

LOL, mine is just the opposite, I can fill it up and it wont go past a half tank. The good thing is that I always have more gas than it show, the bad thing is that I show empty long before I'm out.
