what oils and springs b4

[rondoolaa]

hi,

i have a team associated b4.1 with threaded shocks,
it has the 2 standard holes in the pistons,
i was hoping for some advice on springs and shock oil for the shocks on this car,
i only own schumacher oils 25, 35 and 100, but can obviously go out and buy others,

the track is offroad grass with a couple of jumps,
any advice appreciated,

Silver rear springs and either silver or blue front springs...... Oils are usually 27.5. 30. 32.5. Associated.
