Box stock is tough as any mistake is magnified because of the lack of power. Having done a bunch of full scale amateur car racing in my younger years you need to consider a box stock car very much a momentum car.

I find the PN KS tires to be faster than the Kyosho’s by a significant margin, on my box stock car I am running soft rears and firm fronts currently. Finding the correct tire combination is literally 85-90% of your set up.

as mentioned the box stock cars are pretty down on power so you need to do everything possible to extract all the BHP available. Break in the motor, keep the motor clean and use the Bachman brush lube, it works and lastly when you go for a fast stint charge your batteries at a bit higher rate to get some heat in them and lower the internal resistance, it makes a difference.

As far as driving goes, try to link turns together as much as possible, use as little steering as possible...every time you use steering you are slowing the car down. I have found that taking tighter lines refuses the distance travelled and saves significant time. I never use brakes and please experiment with how fast you can enter a turn using later and later “braking” points. Basically all the rules that apply to full scale hot lapping apply to these cars.

Lastly....practice, practice, practice. I would not worry to much about chassis set up yet, when you can do 75 laps and only have 2-3 errors then you can start worrying about fine tuning the balance of the car. While it can be frustrating at times having fast laps to chase will give you something to work towards and make you a better driver and And chassis engineer.

One thing I do recommend is spending some time on the front suspension and making sure everything moves very smoothly, this is hugely important in my eye. I am also a fan of doing inverted king pins. Some say it increases the unsprung weight of the front end but to me is just helps make a smooth front end.

great to have you on board.
