RB Flywheel?
I recently purchesed a RB Light Steel Flywheel from a user but is doesnt come with the counterweight. Its for an '83 12a. Do i just use the counterweight from an auto RX-7 from the same year or what? I tried emailing RB, but nothing.

Adding a little more information for a wider year selection for your counter weight see http://www.mazdatrix.com/faq/Rcounterweights.htm

Alot of the steel flywheels require the aluminum spacers between the pressure plate mounting bolts and the surface of the flywheel. If yours is the type make sure that if you do not have them that you get them. If you try and install the system that requires them without, you will have major problems.

Good question^. I would contact Racing beat and ask them if theirs requires the spacers. What this does on some of the aftermarket flywheels is ensure the "Step" or distance from the pressure plate contact point to the flywheel depth is the correct height.
I know that Mazdatrix now offers this kit. And the last time I needed info on this I contacted Midway(centerforce) and asked them where I could get these. They refeered me to Racing beat and gave me a made up part # to give to them. So when I contacted Racing beat and told them what I needed and the number that Centerforce had given me they ordered it.

The steel and aluminum flywheels are universal. They can be used with either 215mm or 225mm clutches. You only need the aluminum spacers and longer bolt kit if using 225mm clutches. If using 215mm, the stock pressure plate bolts can be used.

Where did you get your info?
I am technically correct but I suppose I should make a few distinctions for the benefit of the newbies here.
'83-'85 12As came with 225mm, as did '84-'92 NA 13Bs. '82 and older 12As and 13Bs came with 215mm. Either clutch can be used with the aftermarket flywheels as long as you have the correct rear counterweight for your rotating assembly (and correct front counterweight for certain 12A models). So technically either size of clutch can be used regardless of whether your engine is a 12A or 13B.

That's why my statement is as it is. If you noticed that I stated if "Yours" is this type you will need the spacers.
But thank you for the added info as to distinguish what size requires the spacers.
