Aug.21 (GMM/Inautonews.com) Sebastian Vettel’s helmet livery tweak for the Belgian grand prix conforms with the regulations.

That is the claim of the German’s helmet painter Jens Munser, as the Ferrari driver prepares to mark his 150th career grand prix at Spa-Francorchamps.

Vettel, famous for using dozens of different liveries throughout his successful career so far, has been a critic of the new-for-2015 rule requiring every driver to field an identical design at each grand prix.

Now, his white helmet is turning chrome for Spa, Munser revealed to the German website f1-insider.com.

He said: “What is important is that the design is not changed from the front, so that the recognisability is the same.”
