Guys, I am 100% sure the db01R uses the high traction trf511 wishbones
54141 and 54142.( the thinest but carbon reinforced ).
The standard db01 ( not the R version) uses 51311 and 51313. ( thicker 501x mould but plastic). The strongest would be the standard 501x wishbones 51275 and 51279.( thick and carbon reinforced ).
Now to throw a bit more in the mix you can also get a high traction soft arm 54283 ( the thinest type as 54141 but plastic not carbon reinforced ) but these seem to only be available for the front and not the rear
hope this helps
