Lightbulb Toyota CHR hybrid MODS

Dear folks
I am new here and I would like to ask you if anyone have Toyota CHR hybrid 1.8L ???
I would like to know if someone done any eco modder specifications to his ar and if it as worth it ?
1)I thought about putting smaller rims now its 18inch (The easiest mod)! to 16 inch and more like smooth than sportier!
2) Remove the big spoiler from the back not sure this will make better aerodynamics in big speeds?!
3) Change the sparkplugs to a irridium ones .

Do you think is gonna help the mileage of the car and economy?
But big influence not just 0.1L/100KM?

The C-HR Hybrid isn't available in the US, where most of us are, unfortunately.

I would be hesitant to remove the spoiler; it's almost certainly there to reduce drag and rear lift. Most of it is slotted:

...probably to duct air over the rear window where it would otherwise have detached.

16" wheels are probably a good choice, especially if the wheels and/or tires are lighter--the 16" aren't even available in America.

It's probably already got iridium spark plugs (not an ecomod anyway, unless you consider longer spark plug life).

Does the C-HR Hybrid have the automatic grill shutters found on the Prius? If not, you can probably block some of the grill area.

My 2 cents:

-Raising tire pressure is almost always low hanging fruit.

-Change your driving habits. Drive more slowly on the highway and minimize your speed changes in town. See the Driver's Ed section for details.

-Going with smaller wheels will probably improve ride quality (and offset some lost with higher tire pressure). You may get a small but noticeable improvement in acceleration, and fuel economy might improve a very small amount. However, the wheels are unlikely to ever pay for themselves.

-You'll not gain anything by changing spark plugs, Toyota likely already optimized them.

-I wouldn't touch the spoiler.

The CH-R is a shoe. It's not an aerodynamic vehicle at all. Chances are good you'll see the largest improvements by simply driving more slowly since aerodynamic drag goes up exponentially with speed and you're not starting at a good baseline anyway. You may also consider some things like improved underbody paneling (it's probably not half bad from the factory), smooth wheel covers, mirror deletes, a partial grille block, prewarming (e.g. block and oil pan heaters).

As above, i'd leave the rear spoiler in place personally.

Wheels - get the lightest you can afford. On my civic i have some rays (forged) wheels that are significantly lighter than the factory heavy cast rims. Bought them used so not that expensive.

If you're swapping wheels, then consider also getting low rolling resistance tyres. My pirelli p7 "blue" are A rated for roll = less fuel used.

Also, as above, pump them up - you can go a bit higher than the factory recommended levels (stay within the tyre limits though) ride suffers a little, but economy goes up.

For some reason Toyota marketing folks think that folks all want a high riding 4x4 looking vehicle, so the CHR like many other sits really high. check out if you can get some lowering springs (eibach?) to reduce ride height - this not only helps your mpg but also looks cool

Other than that ^ your driving style will be biggest impact on fuel economy - lots of good eco driving tip on the wiki in this forum.

To give you an idea, with the light wheels, lowered ride height and low rolling resistance tyres added to my civic i saw about 5-10% improvement in MPG. If there were any easy things to do that gave you a big improvement then toyota would have done them already biggest impact you can make is your driving style.
