Designed for touring cars and sports cars, the Supersport and Sport divisions feature cars ranging from low A-class to high S-class rank.  

Supersport:

Base PI is 650.  I intend on having very few street cars above that PI.  

The power limit is 600HP.

With the addition of the GT500/GT2/GT4 group, the GT4 cars can participate with the -5% handling handicap.  

A PI adjustment system will be instituted to help level the field.  This will take the form of mainly PI penalties and less commonly in the form of rewards.  

Lamborghini Diablo GTR:  700^
Lotus Evora Type 124:  694^
Maserati MC GT4:  689^
Porsche GT3 Cup '05:  698^

^: -5% handling

Sport:

Base PI is 510 for AWD, 520 for RWD, and 530 for FWD.  
SEAT Leon Supercup:  533

The power limit is 450HP.  

Regarding eligible cars:  if it fits the category, it can run.  I have no year or duplicate model restrictions.  Refer to Car Performance under Series Rules for information regarding homologated builds.  

Remember, performance will be equalized throughout the series.

Edits: Included GT4 cars into the SS1 field and SEAT Leon SC into SS2. Clarifications regarding eligible cars were made.

Edit: Changed Supersport 1 and Supersport 2 to Supersport and Sport. This is due to my misunderstanding of class structure in the real Dutch Supercar Challenge. The difference between 650 PI and 520 PI is much more similar to the difference in the real Supersport classes and Sport classes. Sorry for any confusion that might crop up, but I feel like I should deal with this now rather than later.
