The class structure and index for the 2020 Tire Rack SCCA ProSolo season have been posted on SCCA.com. The official classes can be viewed here; the Pro Solo Index in its entirety can be seen here.

Among the adjustments for the classing in the 2020 season:

• The number of Street Index classes has been increased to five for the 2020 season, including a class for selected AWD vehicles. The AWD Index Class places those cars with a potential for a quicker launch time into a separate and more-balanced class.
• Ladies Index cases have been consolidated from four to three, moving SSC to the L3 class.
• Three new open supplemental/exhibition classes have been added for 2020. Xtreme Street A (XS-A), Xtreme Street B (XS-B), and Electric Vehicle (EV-X) will not be able to earn contingency prizes, points, or participate in the Super or Ladies’ Challenges.

The ProSolo Index has also been posted. The PSI committee has more than 160 years of collective experience with Index classes as ProSolo competitors, so each member understands the significance of the multipliers to participants. The committee based the 2020 numbers on the 2020 RTP Solo index, which has significantly more data points than the 2019 PSI, with consideration given to launch characteristics and advantages. Historical data validated the approach that this year’s team followed.

The full index may be found here.
