Colin Kolles gave little away at Sepang when a gaggle of determined reporters pressed the team principal for a comment about Spyker's protest against the Toro Rosso squad.

"The situation is very clear and soon it will be very clear to the whole world," he said.

Kolles added: "It is about rules which must be obeyed.  We will see what happens."

Thursday, however, passed without a decision from the stewards about the official protest, and morning practice for the Malaysian grand prix kicked off on Friday with both Vitantonio Liuzzi and Scott Speed in action.

But it has emerged that Spyker's new evidence about the alleged illegality of the STR2 single seater could be damning.

The Dutch squad has reportedly given the stewards detailed drawings of the 2007 Toro Rosso single seater -- with 'Red Bull Racing' logos clearly visible.

STR had clearly anticipated trouble by sending a lawyer with the race team to Malaysia this weekend.

Stewards, meanwhile, visited the STR garage on Thursday night and departed with car parts.  Toro Rosso staff, too - including new technical director Giorgio Ascanelli - were observed approaching the stewards' quarters with additional car parts.

A spokesman for the manufacturers' group GPMA indicated that other teams are concerned about the whole 'car sharing' issue.

Xander Heijnen told AP: "You're changing the DNA of the sport completely."

"If it is no longer the pinnacle, if it's no longer extremely difficult to get in and even more difficult to survive, then what is it?"
