"Which options parts do I need ?"
Report by Yukijiro Umino

As many of you anxiously await the arrival of your new BD7 kits this week, here are some comments from Umino regarding the most commonly asked,

@ "Which options parts do I need?"

However, since not everyone runs on the same surface conditions, provided below are some recommendations based on the team's experience at both races and testing.

šFor medium grip asphalt/tarmac and low grip carpet tracks
œB7-203 Aluminum special servo mount
œBD-010FW Front double joint universal shafts
Standard kit suspension arms are recommended, as for these surface conditions the kit arms allow the car to be more compliant, and provide easier drivability.
 
šFor high grip asphalt/tarmac and high grip carpet tracks
œBD-008FG Graphite front arms
œBD-008RG1 Graphite rear arms
œBD-415SG Graphite steering blocks
œBD-415RG Graphite rear hub carriers
œB7-203 Aluminum special servo mount
œBD-010FW Front double joint universal shafts
Changing the suspension pieces to graphite will provide sharper response and improved handling. On tracks where grip-rolling is an issue, it is recommended to at least change the front and rear suspension arms to graphite.
