This is a rear counterweight to fit the 13b-REW found in the RX-7 FD3s
These counterweights are required if you are installing an aftermarket lightweight flywheel such as our Racing Beat lightweight flywheel or an uprated clutch/flywheel kit.
Make sure your order one of these with your new flywheel or it cannot be fitted.
Please note that this item is compatible with the 13b-REW engine found in RX-7 FD3s if your using the 13b-REW Engine in another vehicle this is still the counterweight you will require.
