Jai yen, yen krap khun phee....
I don't think it should be that much of an issue, it will be the second time he drive the car on the track (if ever)..
K. Henk is a good driver with a very good on-track etiquette, and he understood the situation with his car compare to our "daily driving" cars. Remember, the car still need to be fine tuned too..
BUT.... I shall fill you all in on that tomorrow night, after I drive with him at Bira tomorrrow krap.
