i want to get my rank uploaded.. like GPLRank if anyone remembers that, but what do i need to do?

Im assuming i have to do all the tracks but do i have to use all the cars on each of the tracks aswell?

Go to LFS World, click hotlaps, then MHR, then rank info. Explained there.

where is 'rank info'

never mind found it.

Take a look at picture

The nutter rank includes every single combo. Then there are the individual car ranks too.
