The front rubber bumper protectors weigh 0.8kgs each. I just took both off the front of my car to save 1.6kg or 3.5lbs ish. My car is front heavy so I'm staring at what I can pull out of the front.

Car back after cage work

2800 dollars later, the car is back with NASCAR door bars, the driver seat attached to a steel frame rather than the floor, a starter button, no steering lock, new window nets on each side. The car now weighs 2529 without me in it with 5/8 tank of 91 gas in it. My tank is 21 gallons so thats 82 lbs (6.25lbs/gallon) so the car weighs 2447lbs no gas. I'm weighing 185lbs right now which puts the car empty with me at 2632lbs. Finish the race with 2 gallons means 2650lbs ish. I'm hoping to lose 30lbs between now and June so that drops me down to 2620 with 2 gallons which is fine. The minimum weight is 2600 with the driver.

The weight balance with me in it right now is:

LEFT 1390 (51.2%) RIGHT 1324 (48.8%)

FRONT 1344 (49.5) REAR 1370 (50.5)

LL/RR 1288 (47.5%)

The total weight is 2714lbs with I think 5/8s gas.

My garage floor slopes down slightly towards the rear of the car so the numbers may be off slightly.

Gutting the doors of a Porsche 944

I just gutted my doors. This involved removing the black fascia on the door. Next, unbolt the electric motors. The motor and scissors should be loose in the door. The glass just pulls out. This weighs 3.8kg/8.36lbs per side. Once the glass is out the remove the motor by pulling the scissors through the upper hole in the door. This is the whole between the door lock and the door pull. The scissors can be pulled up through this and then the motor will follow. Don't forget to unplug the motor cable. I found this to be very difficult. The motor and scissors assembly weights 2.6kg/5.72lbs per side. The door liner weights 1.6kg/3.52lbs per side.

The total weight reduction so far is 8kg/17.6lbs per side or a total of 16kg/35.2lbs for the glass, liner and motor.
