The dampers are Yokomo Big Bore with gold titanium shafts. After test driving today, I removed the electronics, so it will run if you install the electronics and tires. I believe the alignment is also fine. If you wish, I can include the blue Z body I have listed separately for an additional 5000 yen. If you leave a comment, I can provide additional images and answer questions like "Does it have this?" or "Does it have that?" It has only been run on indoor P-tile.
