This set contains a pair of raised rear wings, one of these (Type S) is for the RX-7 FD3S. The same wing can also be found in the RX-7 FD3S Mazdaspeed A-Spec GT-W Wing kit.

This set contains three high mounted rear wings, one of these comes from the FD3S C-West kit.
Apart from the wings, a couple of extra parts are still on the frames including the base of the recessed C-West headlights, this may come in handy for converting a Bomex, Vertex or A'pex FD3S kit, since those kits contain the clear headlight parts but not the base.
A decal sheet with carbon weave print is included in this set.

This set replaces the earlier GT Wing parts pt.2 set.
The set contains parts for three high mounted rear wings, one of these (on the frame marked '01-41-1') comes from the FD3S C-West kit.
Apart from the wings, a couple of extra parts are still on the frames including the base of the recessed C-West headlights, this may come in handy for converting any Aoshima FD3S kit that includes the extra clear parts frame marked '01-42-1', such as the Vertex or even the '98 or Spirit-R FD3S kits, since those kits contain the clear headlight parts but not the base.
A decal sheet with carbon weave print is included in this set.
