My friend and I are looking at getting new wheels. We really like the Suzuki Twin wheels, color-matched to the car. But they are only 12inch in diameter. Will this be a problem for the front brakes? Might need to use a hub spacer.

Thank you from the USA!!

Attached is the Suzuki Twin with the wheels we want. They are hubcaps on steel wheels.

Hi,

the easiest way would be to measure directly on your Twingo, depending on the version they are equipped with 13 or 14 inches rims with a different diameter of the brake discs (9,4" or 10,2" + break caliper)... It's to be checked on your Twingo but it is undoubtedly impossible.
The fixing centers (4x100mm) may be different with the Suzuki model and you will need an adaptation spacer (risk of friction on the fenders of the car).
It will also be necessary to change to a greater height of tires to find the same diameter (and speed) of rolling.

Good continuation.

by the way, the speedometer will be different too and can be of 10% relatively with the reality so...
