How are you applying traction compound and what are you using?
Are you using tire warmers?
Sedan setups are kinda complicated because one adjustment may have one effect on power and the opposite off power.
Is your son's understeer happening when he lifts to enter corners or when he is rolling on the throttle? Less front droop can help an on power push. This reduces the weight transfer to the rear on power.
Tires - Sorex 36R, inserts B-Med 3 runs at the start
Traction Compound - Buggy Grip 2 at night
Tires warmers - Yes 50deg C, track temp 30deg C
Under steer is mid corner to exit at full throttle more or less, it turns in ok.
Using the Tekin speedy now the car is faster at the top end, it allways had a bit of a push with the SPX but now he is having trouble keeping a tight line.
