Thank you SparkyDave. to be honest, i still dont know how to check lap time from lfsworld.net. the price is too expensive for me. if i have 24pounds, i can drive on our Shanghai's Formula 3 track for 50mins with my own car. but i will think about it. I am glad to know u guys.
No, you won't need a license to check and to upload your own hotlap to LFSWorld.
Go Here and if you're asked to enter as guest or user, choose guest. Youll be taken to a page with laptimes. If you want to upload your own for others to compare, register, and check the Upload a hotlap thingy at right.
