You will also want the graphite upgrades as well if you want to go to a true SB Pro setup.
you may want to do the following as well as what ThanH has listed:
1. Battery post upgrade (described in the FAQ to stiffen the chassis)
2. Steering arm update (if you can, take pics of what you have and I can let you know if you have the newer style)
Also, you should look into purchasing the new spur gears, max size I believe is 74 tooth as these will fit the V1 series of vehicles and give you much better gearing options than the 70 tooth currently does.
If anyone wants the V1 faq, email me at email@example.com
. I am hoping to finish updating it this weekend.
