Dezoris

The 02 spec is still not good enough for maximum bite namely for autox.
The biggest quickest thing you can do for the car is an alignment.

-1.5 to -2.0 camber rear

1/4-1/8 toe in rear

-0.6 to -1 camber front
1/8-1/16 toe out front ,

it is a whole different car.
With a similar alignment or those specs the S03s peform very well.
Pressures on these tires should be no more than 38PSI cold.

They have a stiffer sidewall than the S02s and 95% of street tires.

Again for drag this does not apply. You want virtually little or no camber in the rear, and thats a hug trade off.
