You can unlock all the parts you want and
upgrade your car to the max without having to
cheat by just saving or earning a lot of money.
Do previously completed races and bonus events
to earn some money, then buy a performance part.
You will notice the next part of the same type
(the better version of the one you just
purchased) now becomes unlocked. If you keep
buying every part you can find, more parts will
keep becoming available for you to buy.
Breaking The Bars
On High Jump, do not press R when going up the
ramp. When you leave the ramp, and if you have
enough air, you will go through the bars and
crash into the ground. Note: Your car will get
Get Stuck In Fence
If you go far enough in the High Jump bonus game
(hold R at the bottom of the ramp, then release
about half a second off the ramp) you will hit
the fence wall and get stuck in it. If you wait
long enough, the rag doll person will start
sliding down the fence.
To earn an easy nitro boost, do not try to plow
through lots of big heavy objects on the side of
the road, as this will only slow you down and
you might get stuck in it. Instead, look for
cones lining the track and hit those small
cardboard boxes. Also signs are good to run
through. These objects do not slow you down, and
will earn nitro. Also, if you are going to slam
into junk on a turn, try and slide sideways into
it. You usually will slide or bounce off it,
losing less speed and you will not get stuck.
This also works well with roadside fences, where
you can just rub up on them and knock them down
sideways instead of ramming through them
