Weight add to the RB5 SP2

[carlin]

Hi Guys,

What weiught do i need to added to the car?
I know it will need some up front was looking at the GHea racing stuff but seemed bit priccy is i can get away with running normal weight upfront

Th car is kit built -
With goodies inside
Ko Prop Low Profiel Servo, LRP SPX Speedo, KO 408S, LRP 5300 lipo, X12 8.5t motor

Was thinking of adding 60g behind the servo??

Also i got AC rear carbon shock tower for the RB5 it will fit the SP2 wont it?
