The improvement in handling was phenomenal, however the hit to efficiency was almost as phenomenal as well.

Looks good....For a mazda guru like myself, Ill be looking for some MS3 wheels for my LEAF. I drive 68miles RT mostly 45-50mph speeds and using 4-5bars each way, So an extra bar with better handling/wheels...Ill take it.

On the topic of Mazda rims, while I was rotating the tires on my Mazda5, I figured I'd try them on the Leaf. They are 17x6.5 so they would have been a nice 17" upgrade without going any wider but the rim would NOT clear the Leaf's caliper....

The offset on the 18" Mazda rim, I believe is 52mm which was really close to the caliper, so I put 5mm spacers on the fronts only. The rears were no problem.

Big improvement in wet handling. Drove in rain today with the wider ZR (new to me-used) tires and at least a 100% improvement. Even accelerating on corners, little or no wheel spin.

Having said that, I wish I'd have upped the diameter and tread width both about an inch or so (you can see why I'd wish that in the pics :) ). There seems to still be quite a bit of clearance in all directions still, so when it comes time to replace the tires I plan to try that.


I wonder how hard it would be to lower the car slightly? Better handling, better aerodynamics in additional to resolving your wheel well gap complaint.

TEIN is the only company that has any suspension parts that I am aware of.

They have their H-Tech lowering springs P/N SKK32-G1B00 which according to specs lower the car about 1.4".

They also have their TEIN Strees Basis Coilovers P/N GSK32-11AS2 with adjustable ride height, but from reviews it's going to be pretty low.

The problem is getting them - one reliable method is through nengun.com where the cost is about $500 / $1000 respectively plus shipping.

There are no other easy ways to lower the car slightly unless you are handy with a welder and know how to lower spring-perches on the front struts - for the rear you pretty much need a new spring.

If the springs were ~$200 like most of their other springs I'd give them a shot. Or I might spring for the coilovers, but bump-travel especially in the rear seems to be too limited for what I'm looking for.

Hi defiancecp,

I saw the rims you purchased were 18x8, do you know the offset by any chance? Even better if you have the PCD as well :)

BTW, it was mentioned briefly earlier in the thread....but reducing "unsprung weight" is worth 2-5 times reducing any other weight in the car. So saving 1 kg per corner is more like 30+kg in overall weight.

Even though this is an old post I would like to bump it and add another question.

Since using bigger wheels gives worse mileage, would using smaller wheels give better milage? With wheels I am asuming it only means smaller/larger rims since the diameter of the wheel must be the same based on legislation (at least here in Norway, and using a smaller wheels would make the speedometer unreliable).

Based on what has been written in this thread on the aero dynamics of the wheels, would it not be better to have no spokes? Like a cover over the rims to make them flat? In that case would it not be possible to make a "snap on" cover for the rims? I will gladly sacrify my dignity and looking like a moron to get just a few miles extra on those "just out of range" trips.

Are my assumtions wrong? Or am I on to something here?
