The FIA is confident the Australian Grand Prix will not be mired in suspension system-related controversy after asking certain F1 teams to change their designs.
Ferrari prompted a row at he start of the year when it wrote to the FIA for clarification on 'trick' suspension systems it felt could illegally aid aerodynamic performance. Though the letter was framed as a simple enquiry as to whether Ferrari could implement such systems, it was aimed at challenging designs pioneered by Mercedes and also used by Red Bull.
The FIA followed up Ferrari's letter by stating that teams had to prove their suspensions were not designed to artificially aid aerodynamics -- enforcing Article 3.
