What rear diff oil is best when using a one-way?
The track has a sweeper on to the straight but has a fairly tight corner at the end of the straight (which is still high speed) then another straight after. Also has a tight hairpin in the infield. The traction is ok but the track is quite rough.
Will a tighter diff give me more traction or will a looser diff.
Please explain.
Also what shock setup would you recomend for a bumpy track?
