To add to sKyNeXu5's guide, you can also unlock this achievement with the AI Driver level at 0, or whatever you choose. That has no affect on this achievement. It is just basically about the Assists, so no brake assist, no driving line, nothing.
Britain Short is also a great quick circuit.
On Elite Proficiency, the only real challenges you may face is the Anti-Lock Up braking and Traction Control are off, so go slow when approaching corners and accelerating to avoid loss of control.
Since you don't have to win, i would suggest setting up "One-Shot" Qualification. Once Qualification starts,
and select "Retire From Session". This will put you last on the grid so you don't have to be in the middle of the pack, you can just cruise along at the back.
For Manual Transmission,
is upgear, and
is downgear. Don't forget you need to be in R to be able to reverse:
to move forward. You can just ponder around in 4th or 5th the whole Race if you need to, it really doesn't matter.
For Manual Race Starts, hold
at the same time. DO NOT let go of
when all red lights shine, keep holding a little bit longer until it says to "Release Clutch" (
) on the bottom right of your screen, or when you see others moving.
To make it even easier if you require it, you can adjust the weather to make sure it won't be raining.
To set Qualification, AI, and Weather:
--> Once you select your track (see sKyNeXu5's guide if you need to know how to get there), the next page will be "Weekend Structure"
--> Set Race Length to 3 Laps
--> Set AI Driver Level to 0
--> Set Qualification to "One-Shot"
--> Have no Practices
--> Set to 'Elite' and don't adjust anything else within this tab
--> Change the first option to 'Clear (Dry)' if you wish
--> You can also change the time of day here as well
Proceed, Retire from Qualification and just finish the Race, then you will unlock the goods
