Thank you for viewing my product page. I owned a Yokomo 2.0 with almost all the optional parts. When the SD3.0 blue version was released, I transferred the aluminum parts I was using on the 2.0. Then, as blue parts were released one by one, I replaced them, and before I knew it, most of the aluminum parts had been replaced with blue ones, leaving the black aluminum parts unused. The aluminum parts are expensive, and I thought I could return it to the original SD2.0 by adding a few parts, so I kept them, but I was hesitant because I didn't have the confidence to assemble it to the point where it could run. Therefore, I decided to sell them as parts, hoping they can be utilized. I think some of them can be used not only for the SD series but also for the YZ series. The items in the images are all that are included. I am not very familiar with drifting, so I think it would be best if you could judge by looking at the images. Thank you. #Yokomo #Drift #AluminumParts #SD2.0 #SD3.0
