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.
