did u get the TRF pistons? they are much better.
i use 2-holes and 40 oil all round.
front shock position
top centre hole
bottom 2nd hole from inside
rear shock position
top centre hole
bottom innermost hole
these are my preference so you may want to experiment the different mounting position to suit the track
by the way, how high did u jump and land?
where is the tamiya race? RCI?
