MPG reading is coming up!.

- Lighter aluminium wheels are in place in front and in back of the car.
- Lighter glassfibre hubcaps are in place. Attached by zipties .
- Tinted my windows
- Installed lowering springs

Best tank so far is my last tank.
2009-06-29 843.8 mi. 11.81 US gal MPG71.45 US

100% trip. avg speed 84 km/h. Could ave hit 3l/100km mark but rushed 80 km at speed of 77 mph. That rose my tank consumtion from 3.0 to 3.2! So keep steady max speed limit if you want good looking mpg figures. I could have hit easily 1000 miles but filled up in my usual station.

- Installed lowering springs in the midle of the tank.

Results:

- best coastdown test end speed 77km/h (+1km/h).
- best 75km "test leg" consumption from 2.7 l/100 km to 2.6l. Also that route average speed was highest of so far 80 km/h. So I see best mpg figures with higher speeds .

Next mods:

- install my almost ready glasfibre hood. ~6kg +aero effect on wipers
- new more tear drop shaped front bumber with wire controlled grill block ~3kg
- flat undertray
- Side skirts
- more weigth savings

Next target:

Try to keep the tank consumtion under 3.5l/100km.
