is their part essentially the same as the original mazda part? are their flywheels compatible with mazda counterweights?

did a quick search to no avail :[

thanks!

 

Aftermarket flywheels usually replace the big heavy factory one piece mazda one.

Get the counterweight according to the engine and rotors you have.

 

You can use a Mazda Stock counter weight with an Aftermarket Light Flywheel(as long as the Flywheel Installation Requires it)....Just make sure the Counterweight(which Comes from the Automatic Transmission'ed Version of the Rx7..it is behind the "flexplate") is the Same series as the Engine..so S4 Counterweght for an S4 Engine..No matter if it is an N/A or a TII..the countereight just has to be meant for the Series..(so s4 CW will do a s4 N/a or TII,the S5 Counterweight will do for a s5 N/A or TII).
