I'm considering building an autocross (SCCA racing) car out of my wife's 92 DX hatch. The rules also allow the CX/VX in the class (F Street Prepared), and allow for update/backdate any parts from those models. The CX/VX are 80-100lbs lighter than a DX on paper, and I'm wondering how easily I can reduce the weight by making a DX more like a CX/VX, piece by piece, and what would be worth doing.

Does anybody know relatively accurate weights for these parts?

-tilt steering column from DX/Si/EX vs fixed steering column from CX/VX
-12lb gas tank from DX/Si/EX vs 10lb gas tank from CX/VX
-AC system weight
-is the extra sound deadening in the DX something in the doors, etc, or is it the undercoating and thus not really removable?
-side molding trim on DX/Si?
-rear wiper on DX/Si.. is there a separate pump in the rear of the car, or is the washer fluid pumped from the front?

thanks!

 

all I know is my CX weighs in under 2000 lbs, thats equals a happy me, just took out all the spare tire crap and back seats, spare is useless when you're lowered unless you have a full size, and maybe the Special Edition wheels help as well since they weigh next to nothing, making the DX light wont be much of a task, just start taking basic crap you dont need and keep weighing at a truck scale if possible.

 

i do believe u mean gallons not pounds

 

No 5th gen hatch had A/C from the factory so you can't really count that, they were all dealer installed. Probably the biggest weight difference in the CX/VX comes from the manual steering rack, and in the case of the VX the wheels.
