quick question

You can get away with a firmer suspension and chassis when you use racing tires because the tires are capable of more grip. Racing tires allow you to use a lot more horsepower for the same reason.
 
With racing tyres more grip equals more cornering speed so the suspension may be stiffer.

You can brake a lot quicker too but that wouldnt be tuned differently. The LSD may have to be changed as with racing tyres more grip = better traction so with sports softs lets say youd get more wheelspin.
 
You can run shorter 1st and 2nd gear ratios on racing tyres to get that acceleration boost out of hairpins. On sports tyres you need longer ratios to hold the wheelspin back.
