Ferrari changed floor design

(GMM) BMW figures denied that any modifications had to be made to their floor design ahead of the Malaysian grand prix.

It is certain, however, that Ferrari is running a slightly altered underbody for the beginning of Friday practice at Sepang, after separate confirmations from Felipe Massa and designer Aldo Costa.

Renault and Honda were also using designs with the offending flexible springs in Melbourne last month that had to be changed, we have learned.

"The only effect (the modification will have) is that our floor could now break over the curbs," Costa told the German specialist magazine Auto Motor und Sport.

Brazilian driver Massa, meanwhile, told reporters in Malaysia that he tested the new underbody last week and noticed "no difference" compared with the former specification.
