Recently I decided to pull some weight out of my car in the hope of improving my lap times.
I decided to fit a fibreglass dash and remove the heater and fan as well as all the sound deadening in the car.
The demister function is now performed by a little camping hair dryer which works very well.
So, below is a breakdown of all the bits and their weight, in total I managed to remove 35KG.
centre console 1.7KG
speedo and cable 1.3
ducts 0.5
heater control 1.0
heater 6.3
fan 3.7
dash 9
sound deadening 7KG
carpet 7.4
I hope this is of help to anybody considering doing the same.
cheers
