Hi guys!

First I would like to apologize for my english, because it is not my native language.. So Im sorry for mistakes.
Could someone help me with shock setup? I've owned last version Serpent Cobra BE RTR (based on the current version 2.1).
My option is 6 holes and 1,2mm, V2 springs rear and front (both purple), 425 CST shock oil front and 350 CST oil rear.. What do you thing about this setup for track? Or what do you recommend?

)
I have decided to participat in a hobby racing.. I know, I dont have maybe nothing special, mayby I will be last guy on the track and looser.. But never mind

Stock engine (Dragon RC engine 1650?1850Kv?) is quite weak, so I gonna change it for LRP Dynamic 8 2250Kv with 14 pinion (track is smaller and technical). What do you mean about stock ESC 120A??? Should I also change stock ESC or there's no huge different between this one and for example SKY RC TORO 150A (fully programmable) and sensored ???
Can I race in hobby category with just only RTR or almost RTR set (LRP engine and SKY RC ESC)?
Thank you very much for your advices, tips and help!
