Tamiya 502x build help -- Lee Martin

[cs8sz]

Hi Guys,

Me and Dad just ordered new 502xs and I have been reading Lee Martin's build guide from TRF Racing he mentions the following upgrades to the standard kit:

Aluminium rear hubs
Drive Shafts
Gold Shock bodies
Blue Screws
Shock stand offs (not sure what these are?)

My Question is what is the difference between these parts and the standard kit parts, in particular I can't find part numbers for these parts

Thanks for the help

Chris
