Results are in for the Chinese GP, there has been a slight update following a time penalty for Jenson Button's assault on Pastor Maldanado. JB drops a place to 14th with Carloz Sainz benefiting.

Mercedes were certainly back on it this weekend, Lewis dominated with Nico Rosberg looking flustered and a beaten man. Time will tell if his actions will help to swing things internally in the team.

It was another good weekend for the Ferrari team with Vettel back on the podium and Kimi showing he has refound his pace. Sauber also continued their good early form, but Toro Rosso had more problems with reliability hitting some managers hard with Verstappen's late engine failure.

With the next round (Bahrain) only a week away managers are going to have to act fast if they are going to make any changes. With it being just one week in between GPs, there will be just one time credit to spend. So will you work on hotlap setup with a driver, perform an engine upgrade, swap a selection or save the cash?
