Hello,
Parts are only generated after Sprint Races for teams who are under Level 6.
For a short time, parts were being generated for all Sprint Race participants, however this was recently rectified so that accounts that are higher than Level 6 do not generate parts from Sprint Races.
More information on the fix can be found in
this thread, where Community Manager José Trujillo addresses a similar query.
I hope this helps.
