That's (43:57)a good average to make the kart not too bad in the wet and not too bad in the dry..... but you are a racing driver... you want to be THE BEST in the wet and THE BEST in the dry..... and that's where the 40:60/45:55 come in.

Looked at logically: you can FORCE the kart out of understeer in the dry but you CAN'T (as easily) in the wet. That's why we move the weight forward in the wet.... to MAKE the front work and prevent the rear-grip from overpowering the steering.

While we are at it.... ideally, RAISE the seat on the 45:55 position.

Finally, if you fancy trying all three..... just make sure you have 'plated' the seat mounting holes with stiff ally or thin steel. You can then have three sets of holes without weakening the seat.... we always ran that! so, you'd now have:-

40:60
43: 57
45: 55 (raised seat)

Then..... all you do is TEST THEM!

That's karting!

Oh..... to check the weight distribution while mounting the seat:-

1) Remove the seat
2) cut a flat, stiff plywood board that fits OVER the hole where the seat goes but sits ON the chassis rails
3) get the lad to sit the seat on the board and sit in it. Now you can slide the seat bak and forth to adjust the percentage. You'll see where to mount it in the 'forward position and 'backward position' Mark a VERTICAL line where the SIDE supports align and you KNOW that the rear seat hole will lie somewhere along that VERTICAL line for the three 'percentages'!
