I did that by myself. Just open the 13mm screw at the axis, move the wiper down and then tighten again.

The car got lowered already. Next to come is a closed front grille.

Warm Air Intake installed, upper front grille closed, rear roof wing installed:















The mods i have made so far:

1. Motor oil 5W 40 Shell Helix 7 (less friction losses)
2. Gearbox oil Castrol Syntrans Transaxle 75W90 (less friction losses)
3. Wipers with aero blades fitted under the shape of the bonnet (better aerodynamics)
4. Bigger wheel for alternator. Diameter=75mm instead of 50mm (less drag)
5. Lowering ride height by 40mm front/back (better aerodynamics and performance)
6. VR6/GTI front lip (better aerodynamics)
7. Skinniest tires by OEM inflated to max sidewall 175/65 R14, low rolling resistance (better aerodynamics, lower rolling resistance, 2% longer gear ratio)
8. Smooth wheel covers (better aerodynamics) but i'm looking for completely closed ones
9. Rear wing (better aerodynamics)
10. Full closed upper front grille (better aerodynamics, retaining heat in engine compartment)
11. Warm air intake (better combustion, less pumping losses)
12. Added Liqui Moly CERATEC to engine oil (less inner friction)

Next to come: Antenna deletion, cruise control, partial blocked low front grille, tire spats.

Warm air intake can make a significant difference in mileage, especially in cold weather.
Welcome to the forum.

Not so sure the cruise control will help unless you are on almost perfectly flat road surfaces. I find when driving in hills I can anticipate the grade changes and use them to improve my mileage. Gradually loosing some speed uphill then letting the downhill portion increase your speed (even coasting if practical and legal) uses less fuel than standard cruise control programming.

Everything else looks great, especially the ducting for the warm air intake, which looks like a factory installation.

Thanks a lot.

Yes i know that a factory cruise control reacts in the opposite way it should do for hypermiling. We haven't much flat roads here in South Germany so it wouldn't work perfect for me. But i simply don't want to miss the comfort that comes with a cruise control.

From 03/01/13 on i have to drive over 800mls a week for half a year. My right foot already hurts

New Record: 41,9 MPG (5,62 ltr/100km) on LPG. This is equivalent to 4,5 liters of petrol (LPG has got 20-25% less energy) which means 52,3 MPG on petrol.

243 miles on Autobahn, 200 - 800m elevation, no hypermiling techniques because of difficult weather conditions. Used drag of lorrys for approx. 180 miles.

It was raining all the time and i had crosswinds. Lights were on. Heating fan level 1

I'm pretty satisfied with that.

Roof antenna is now removed. The hole in the roof got closed with (green) duct tape. I've installed a Blaupunkt windscreen antenna instead. Excellent reception - better than before.
