Tamiya Durga DB01 EP Buggy (A cheaper 501X?)

[Toonz]

dcm, im using this setup on the df03 shocks (of cos using the trf piston)

F:3hole + 40wt df03 gold spring
R:3hole + 30wt df03 black spring

is it ok?

i'm going to participate in a race running on ashalpt mix with carpet and about a metre jump. do i need to strengthen the shocks in any way? 2hole? thicker oil? df03 silver spring? do i need to shorten the shocks?

so many questions....

but thanks
