I dont know if they changed wheels for each year so i want the wheels frlom 1993.

 

The 93-95 stock wheels all look the same until you really start investigating. There are at least two types of wheels, shown at http://www.formula3.freeserve.co.uk/dcp_0600.jpg.
The text accompanying the photos I believe is incorrect where it says Mazda changed wheels halfway through the production year. I've seen some thick, some thin on the same car for each year.
Supposedly the thin ones will crack under severe loading, like repeated track days, but I've never seen a cracked one.
And, the thick ones are heavier.
From the examples I've seen, the thin ones have the date codes as the year then 12 boxes, the thick ones don't.

 

OK thanks but what i really need is the wheels ET.

 

Sorry with ET i mean back spacing.

Thought it is called ET in english aswell.

 

See my site, and go to Upgrades --> Wheels --> Offset & Backspacing.

the offset is +50mm if that helps you

 

thanks.

 

so the 93"s have the boxes?

 

The boxes represent the date code. Each month they put a punch in the box, for example March would have 3 boxes punched out. This is a standard industry pratice for injection molded plastics and cast parts. Take a look around underneath some of the plastic interior parts on any type of car you should see some type of date on almost all of them.

Wheels made in 92 are on 93 FDs, wheels made in 93 are on 94 FDs. The earliest wheels are the strong ones, the others are all the weak ones.
