take your time , read the instructions and it will pay you back 10 fold over the years racing
it took me 3 nites of building and i went 0.5 seconds faster than my 415 ever went before i even put the 416 on the set up guages !!!!
now i am over a second a lap quicker with this car then i was and feel the car is more planted then the 415 ever would be
build you shocks with no rebound , use blue front springs and yellow rear
with 1D 1D front blocks and 1XA 1D rear with an extra 0.5mm spacer under the rear block on the front suspension and remove the 0.5 spacers from under the rear blocks if you want a lot of grip
