Ricardo i got Rank 50 a long time ago, the best way to do it, is to beat all those retarded drivers nonstop in Sprint mode.
Some tips on how to raise your rank quicker.
-The more drivers you beat, the more rank points you get
-Beating drivers with higher ranks will also give you more rank points
-Get the best setups for your car on every track, check out the setups part of this forum, look for Viktor Andersons setups, they work the best for me, having these will help you to beat the average driver who are not smart enough to make their own.
-In Sprint mode, sometimes racing against these idiots, you have to give as good as you get, some drivers are happy enough to give you some space, respect those drivers and befriend them, the idiots that want to knock you off schumi style, do the same to them, they are more likely to get frustrated and leave the race before you do, as more often then not they have zero patience, once they realize they cannot win, they will quit the race.
-Practice Practice Practice, get on that time trial and learn to run round the track without cutting, this will help you to pick up less penalties, although it is likely some idiot will give you a penalty anyway, a combination of smashing into incompetent drivers and accidentally cutting track will just get you Disqualified, it is extremely rare that will ever happen to me.
-Even if your not going to finish high in a race, finish it off anyway, you will get some rank points regardless of position, i cannot get why some players decide to leave the race if they can't win, just make sure you don't get disqualified and race right to the end, you never know when a player might have a big accident on the last corner, or which players will have penalties.
-Always remember, make sure every setup you have, starts you on Standard map setting, this is important because if its set to Fast when you start the race, it will glitch out and not work, the only way to get the most out of your map settings is to set it to Standard, then change to Fast as soon as those Red lights go out.
-The first corner can easily make or destroy your entire race, there are certain tracks where it is guaranteed some idiot can not brake properly and just smash you off, here is a list of tracks where it is usually bad to start at the front of the grid, lets go through the tracks:
Bahrain - Not too bad, it is best to try get on the inside and brake quite a lot, do not attempt to go round the outside, it will usually end up being bad.
Australia - This is good, attack the first corner hard and you should end up in front.
Malaysia - Its a hard one, do not go on the racing line, try get on the inside more, as the idiots will usually just fly off really wide on this.
China - So many get this wrong, all you need to do is accelerate in and then let the car decelerate, most of the time the drivers will be well on the outside, brake if you really need too
Spain - Not too bad actually, its usually the second corner which can be troublesome.
Monaco - Terrible! If your at the front you just need to pray you can brake and zoom through that first corner, if your at the back its nasty, you know for a fact players will come off and its just a matter of trying to navigate through them, which most of the time will not work.
Turkey - It depends, sometimes another player will clip you and cause you to spin, i would say to try run wide because at least there is some run off area
Canada - Its alright here, players seem to realize just how tight them first two corners are, even if you get it wrong you will roll across the grass and rejoin after turn 2
Europe - If you can get round it in gear 3 and end up just next to the wall, more then likely you will be fine, if your further back you may want to wait a moment on the run off area on the left hand side before the corner, so you can ride past any players who span off
Britain - Its easy here, probably one of the best starts as there is no need to brake.
Germany - Another easy one, plenty of run off areas on the inside and the outside of turn 1
Budapest - Can be disaster here, i try to take it on the outside, expect many cars to spin off here
Spa - Do not take this on the outside unless you want some idiot to fly into you, get through here on the inside away from the racing line, braking quite a bit, other drivers wont think of this and you should be safe
Italy - Disaster, some players i know if they are at the front, purposely run off onto the grass on the left hand side to let everyone past, just so they can watch all the other drivers destroy each other on the first chicane, i have a better idea, if your first place and you go to brake, some idiot will more then likely nudge into you, immediately stop accelerating and let the car roll across the grass, this will put you onto the next straight well ahead of everyone else with no penalty, i have tested this many times and so long as you do not accelerate after the nudge, the game will not count it as you cutting track
Singapore - A lot of run off area off turn 1, try sweep across from the right hand side, it can be difficult because someone might decide to try take this on the inside which is just dangerous
Japan - It is not so bad here, get on the racing line and make sure you get the turn spot on, guaranteed half the players will go seriously wide anyway
Korea - This is a really bad one, majority of players find it difficult, they will end up on the grass, i find been at the back here is a big advantage, if your at the front you really should consider taking it on the inside away from the racing line, even if you go slightly wide off turn 1, all the other drivers will end up crashing anyway.
Brazil - This is definitely my worst first corner of any track, it is so difficult to get it right, i end up on the grass most of the time, you cant even take it on the inside because it just makes it harder, all you can do is brake at the right time and pray.
Abu Dhabi - Not so hard, just make sure you do not go over the inside curb, there is a little run off area if you go wide, the run down to it is not so big.
I highly recommend you play some banging tunes while you play, get the adrenaline going, swear at other drivers, from my experience racing against idiots, getting really annoyed will actually add to your speed, specially if they get past you and you know your stupidly faster then them
