I've had these for a while. Time to let someone else create.
The RE-Amemiya RX7 creates something like this.
Includes Aero light buckets and some stickers.
Front rear, Sides and overfenders. I still have one more I am building right now.
Made for the 190mm Mazdaspeed HPI shell but it fits on the 200 also with rear trimming.
The Runfree Kit creates something like this.
the bumpers on these include light buckets that sit behind the original body.
And includes all you need for the aero upgrade except the body shell itself.
Cheap at $35AUDeach + Post
