You should get both, and if you're planning on running mid motor at some point, you would need UMW707 as well.

Dialed RB6 right here! Chassis has a slight wobble in it and rear hinge pins were tweaked so I decided to rebuild from the ground up and getting a ton of upgrades! Kyosho steering rack, hubs, vented slipper plates, vented motor plate, Lunsford titanium turnbuckles, titanium screw kit, new hinge pins, all new bearings and will be rebuilding it in mid motor. Also debating on a new servo... perhaps the KO 30102. its gonna be a loooooooong week!

Linked below are the instructions that are included in the hangers. Note the reference section in the middle of the page, to get the settings to mimic the narrow and wide hangers you typically use.

http://www.petitrc.com/setup/kyosho/...5UMW706UMW707/

Actually there is 7 track width positions. The RR dictates the width in most cases and the RF dictates the toe angle. the "A" is the middle setting and then you have 3 narrow or 3 wider.

The shocks don't really bend the shock towers, they push up towards the top mounting holes, and when the springs pushes down, they pull pressure away from the top mounting holes.

Are you saying that the factory plastic piece stretches and contracts as the shock puts vertical pressure on the mounts? I would think that the shock tower's tensil strength is actually pretty high. (relatively speaking, of course)

Yes 7 total but Bob asked, "so there are more than just the std wide and narrow? Interesting. I would like to run a setting that's in between." Thus there are 3 positions (In-B, A, & Out-B) between the the positions traditionally provided the UMW511+UMW512 or UMW514+WMW515 aluminum hangers.

I tried the Avid 4 hole pistons tonight and other then the fact they fit the shock shafts like a donut on a pencil they work great. FYI to anyone considering them that they need a shim to take up the slack....

Its best to just go with the Ghea pistons, they are a perfect fit and worth the few extra bucks.

x2

The Gheas are precision cut, tight fit, zero slop. Can't go wrong. (they are a little pricy though)

Kyosho SP Front Suspension Plate Type-B (UM721)

Type B is what you want if you want to keep it stock according to the exploded view. It's the only part I seem to have to maintain. I've never broke it, but overtime it seems to warp/bend, giving a bit of toe-out to the inner hinge pins.

DETERMINED TO BE AN INCOMPLETE LIST

To make a gear diff for the RB5/RB6,you need the:
  • Kyosho UM605 Diff Gear Set
  • Kyosho UM610 Diff Bevel Gear Set
  • Kyosho UM611 Diff Case Packing
  • Kyosho UM612 Diff Shaft
  • Kyosho ORG045S Silicone O-Ring

If you want you can use steel bevel gear set:
  • Kyosho V-OneR4 Steel Diff Bevel Gear Set, VZW424
