The Inter League series gives the chance for our fastest drivers to pit their skills against some of the best GPL drivers in the world. The rules accommodate all the mods as well as the original 67 cars. The points allocation is designed to reward a strong team performance rather than individual brilliance.
The points awarded are:
| Position | Points |
| 1st | 18 |
| 2nd | 17 |
| 3rd | 16 |
| 4th | 15 |
| 5th | 14 |
| 6th | 13 |
| 7th | 12 |
| 8th | 11 |
| 9th | 10 |
| 10th | 9 |
| 11th | 8 |
| 12th | 7 |
| 13th | 6 |
| 14th | 5 |
| 15th | 4 |
| 16th | 3 |
| 17th | 2 |
| 18th | 1 |
For a driver to qualify as a finisher they must complete 90% of the full race distance.
The races will be run under PRO damage.
Each League will field a team of 9 drivers. The Team Captains will formally allocate the chassis but it is expected that a mixture of all available chassis will be used. The following chassis allocation will be typical:
67s
one Lotus
one Eagle
one Ferrari
one Brabham
one Honda
two Coopers
two BRMs
66s
two Brabhams, one BT19 and one of the BT11 versions
one BRM, driver to choose between P261 and P83
one Cooper
one Eagle, driver to choose between T1F and T1G
one Ferrari, driver to choose between 246 and 312
one Honda
one Lotus, driver to choose between 43 and either of the 33 versions
one McLaren
