Not everything has been mentioned in that list of hop-ups. For example, the TRF Aeration dampers are shown on the car, but not listed as a hop-up. Also, since the R kit includes the under-motor heatsink, it definitely does NOT come with the standard fiberglass tub. The description says it has a new chassis tub unique to the DB01-R. This should be interesting. I hope it has 501X outdrives too. I won't order till I see the manual...
