as far as i know, most of the efi engine out from factory already went thorough balancing process. perhaps, campro engine does went thorough it too  .
it's not necessary to do an engine balancing on a relatively new car with low mileage.
a simple top overhaul is fine. once we opted for complete overhaul, then there is when the engine balancing comes to calculation. it worth every penny.

Go for Works engineering(search google) la. better a lot.

i'm currently using Redline LCP, its about half weight the stendet LCP, not so heavy n not so light
u get engine response improve without so much effect of engine braking..but need to suitable yourself with it for a period..
but the draw back is sound of belt slipping when engine is cold coz the material use is aluminum..
the belt slipping on mythelogy i believe less than redline because of the teflon coated..
