Felipe Massa does not want the use of F1's new adjustable rear wing system to be expanded following its debut in Australia.
After the 'drag reduction system' (DRS) did not overly contribute to overtaking on the Melbourne pit straight, it is believed officials are considering making two activation zones usable for the Malaysian grand prix this weekend.
It was believed teams were working on the assumption that the wings will only be able to be used during the race on Sepang's long front straight.
But Ferrari driver Massa revealed: "We are waiting for the final decision from the FIA to see if we use DRS on the front straight, the back one or both."
I am not sure that allowing DRS on both straights is the best option
Sepang's back straight is actually longer than the one parallel the pits.
"Personally, I am not sure that allowing DRS on both straights is the best option, because I think it might actually make overtaking too easy," said Massa.
"You have to get the right balance between helping the chances of overtaking and having almost too much passing," he added.
