Outboard mirrors ban rule forced Sauber also to revert its mirrors close to the cockpit zone since Spain .
Red Bull was one of the many 2010 teams to revert to inboard mirrors since Spain due to FIA mirror outboard ban regulation .
Wheel rim Carbon fairings, which were extensively used during last years were banned since 2010 season in an attempt by FIA to make pit stops safer . So in theory all teams had to reverse back to simple rims but Ferrari instead moved a step forward and merged the fairing idea into the rim producing an interesting crown wheel rim design . The double concentric rings of different diameter may be attached on the wheel but are considered to be part of the rim , so they are made of the same homogeneous metallic material to the wheel according to FIA regulation article 12.3.
Rival teams couldn’t copy the design due to new 2010 homologated rules ( rims , fuel cell and crash structure are homologated to low down the cost ) as they already run simple rims at the first 2010 race at Bahrain and Ferrari cleverly kept it secret till the start of the 2010 season.
Ferrari’s innovative rim design extracts hot air coming from brake components in such a way that effects less the outer cooler airflow towards the rear , decreasing vortexes and improving aero performance of the car . Rival teams had to deal wheel fairing ban by developing sophisticated front wing endplates to clean airflow around front wheels profile .

Each driver per racing weekend can use :
11 sets of dry tyres : six of the harder ‘prime’ compound and five of the softer ‘option’ compound .
4 sets of intermediate tyres

FIA regulations on tyres
12.6 Specification of tyres :
12.6.1 An intermediate tyre is one which has been designed for use on a wet or damp track.
All intermediate tyres must, when new, have a contact area which does not exceed 280cm² when fitted to the front of the car and 440cm² when fitted to the rear. Contact areas will be measured over any square section of the tyre which is normal to and symmetrical about the tyre centre line and which measures 200mm x 200mm when fitted to the front of the car and 250mm x 250mm when fitted to the rear. For the purposes of establishing conformity, void areas which are less than 2.5mm in depth will be deemed to be contact areas.
12.6.2 A wet-weather tyre is one which has been designed for use on a wet track.
All wet-weather tyres must, when new, have a contact area which does not exceed 240cm² when fitted to the front of the car and 375cm² when fitted to the rear. Contact areas will be measured over any square section of the tyre which is normal to and symmetrical about the tyre centre line and which measures 200mm x 200mm when fitted to the front of the car and 250mm x 250mm when fitted to the rear. For the purposes of establishing conformity, void areas which are less than 5.0mm in depth will be deemed to be contact areas.
12.6.3 Tyre specifications will be determined by the FIA no later than 1 September of the previous season. Once determined in this way, the specification of the tyres will not be changed during the Championship season without the agreement of all competing teams.
12.7 Tyre Gases :
Tyres may only be inflated with air or nitrogen.

HRT was another team to reposition its rearview mirrors inboard since Spain to comply with the new FIA mirror outboard ban regulation .
Following a rule ( article 3.12.7. ) clarification from FIA stewards at Bahrain Mc Laren at Melbourne had to decrease the motor access hole ( apart from the front wing’s sharp endplates ) , located at the central zone .
FIA REGULATIONS ABOUT MOTOR ACCESS HOLE
No bodywork which is visible from beneath the car and which lies between the rear wheel centre line and a point 350mm rearward of it may be more than 175mm above the reference plane. Any intersection of the surfaces in this area with a lateral or longitudinal vertical plane should form one continuous line which is visible from beneath the car. A single break in the surface is permitted solely to allow the minimum required access for the device referred to in Article 5.15.
In plain words Mc Laren run a larger than needed hole to access the engine starter to make its diffuser act partially as a triple decked instead of two-decked , gaining extra downforce .
