kamikaze

well after u beat a boss a bonus race comes up it might be a heat tornamate or a circut and sometimes or all the time there is 2

You will always get bonus races to get more respect.

if the cop dudes are on ther u should spawn a double-d challenge.

Well I did all the races and bonus races but I still don't have enough respect what do I do

You probably still forgot some bonus races, like the ones where you finish a race and then you have to outrun the cops. If you won those races and didnt outrun ed the cops you have to do the races again and out run them.

Do the doble down challang on all races you did so for to all so get a good start to reach number 6
(I'm on number 6)

Win some more races and milestones

Did you get enough respect?Well,you need 42,500 respect points to battle KIRA NAZAKATO"KAMIKAZE".Bonus part challenges are not effectivi because it won't give you respect either cash because it isn't a challenge the bosses gave you,it is just a bonus FOR YOUR CAR!Why don't you try the challenges you didn't complete.

You can also have a race(but not boss events,just the challenges)and reach a heat level of 10,then try to outrun the cops(you must cancel the outrun first and play it again to save your races,respect and cash.
