@ nbla / Tobias:
Concratulations! - TB03R is the best choice! I'd like to continue your list with
-Titanium Hex Screw Set Tamyia #49499 or the cheaper one from 3racing (the original Philips screw are crap!)
- TB03 reinforced Lower Deck #54147 (provides much better feeling - even better than the Carbon one from 3Racing)
- Onroad Spring set White #49382 (or those from Hot Bodies /HPI)
-Don't forget to buy tires - the kit has none included
