I haven't seen one yet. For reference, here is what I have been running in 13.5 and it seems pretty good:

Kit chassis plate
Kit side springs (yellow) just touching
Kit center spring (yellow) with 500cst in shock
Center shock mount plate flipped to underside of servo mount for more inclination
15k Kyosho in 'standard' tubes
Kit ~170mm rear width
5 degree reactive with 4 or 5 degree static (both seem good)
No spacers on front lower arm mounts, 1.5mm spacer on axles
1 degree camber
30k Kyosho in front mini tubes
Kit front springs (think they are Xenon .50)
Protoform AMR, mounted middle of wheel well
Battery back
