A Silver Cup has been confirmed for GT World Challenge America and Pirelli GT4 America SprintX next year, as part of changes to the class structure of both SRO America-run championships.
Announced during Thursday’s ‘State of the Series’ address at the PRI Show in Indianapolis, Silver-rated driver pairings will be permitted in both series, allowing for additional driver combination opportunities.
It comes in the wake of the elimination of the Pro class from GT World Challenge America for next year.
The series, which will retain its dual 90-minute race format for next year with full service pit stops, will now have Pro-Am, Silver and Am classes.
The same class structure will be in place for GT4 SprintX, with GT4 Sprint remaining with Pro and Am classes only.
SRO, meanwhile, will continue to have the freedom of having driver derogations from the global FIA ratings “given where applicable”.
Other changes for 2020 announced include adjusted tire allocations, the mandatory use of tire pressure monitoring systems for GT3 cars and the introduction of virtual safety cars.
No changes have been made to the schedules for either series, which were confirmed last month.
