What does it weigh?

***Disclaimer***
This is not a end all be all of how to do it, I'm sure some race shops or some pro teams will have some opinion... and idc. This is just a car that goes to the track accouple of times a year. All I'm looking to do is improve it and learn along the way.
So I have had the question of... what does it weigh?
A few weeks ago ZR & I picked up a set of Intercomp Scales for weighing/corner balancing cars.
I finally had some time this weekend to dial in the DECH from a corner balance POV.
First off. I wanted to weigh it in 'street' trim.
The Dech with a half tank of fuel (give or take), spare tire, street wheels... etc etc.... came in at 3179lbs

Next up it was to put it into 'race' trim. This involved taking the spare tire stuff out and swapping the track 17x9 with hoosiers on the car.
If I wanted to get super anal about this, I could/should of put my race seat in it along with the race brakes.... it maybe be a smidge heavier... who cares...
The Dech in Race Trim weighs 3083lbs
Not bad! So my spare tire setup was roughly 40pounds and the rest of the weight loss was from wheels and tires... that's close to 60lbs!!!
I also was playing around with the Battery. I had the battery out of the car to see what it would do to the corner balance... turns out the battery I have in the car comes in at 39lbs!
Might have to look into one of those light weight batteries after all!
Anyways!
After a bunch of research, talking to some people in the know, I tried to get the car better in terms of the 50/50 balance.
I firstly reset the ride height on the car to get it where I wanted it to sit. Car has a very slight rake in the car.
So after resetting the ride height, the car came in at ....
LF: 1027 RF: 738
LR: 528 RR: 792
Car was wayyyyyyyyyyyyy off. I think the spread was almost 7% off which in corner balance is off a country mile
As you can see. The LF was super heavy along with the RR.
A bunch of adjustments later..... I got it to this.

A reminder, this is race trim, no driver, half fuel.
I'm also super happy that I was able to get the car this close with retaining the ride height close to what it was at the start. Moved about a 1/16 to an 1/8 depending on the corner. Not bad!
This is by no means perfect... but it's a lot better. My buddy that races from a living says that If I can get the front end perfect, I would feel the difference... but that will be for another day!
So based off of setting the car up with the tape measure... to corner balancing it.
I took 140lbs off the LF of the car and got the car within .28%... I'll consider that a W.
This should make a dramatic difference at a track like TMP with a ton of right turns with it being a clockwise circuit. Should help with tire temp in the LF as well.
If I ever compete in the car, I'll get super anal with how I set it up... Driver in it, passenger seat out etc etc etc.
I'm super pleased with this and can't wait to try it out.
