We have to use the LFS sponsors (Scavier, Rufftweeks etc...).
At the beginning of the season, all pilots have normal cars (maybe 20kg handicap and R2 tires).
For example, the Scavier sponsor want only top 5 pilots etc...
After the 1st race, pilots can received mail with the sponsors offers...
So Scavier can give only 5Kg handicap and R3.
Sponsors can give more endurance, more speed, more regularity...
The system is on work, and we are waiting the Nascar/Indy Lapper too.
