Right, because I am feeling generous, I am going to share how to do this! (Hopefully in a way that isn't poorly written!)
This little tutorial is going to be for the Lotus Elise '96, but could very well work for a lot of cars, so feel free to experiment!
Also, I haven't tested this on a DS3 controller, so I haven't a clue if it would work.
1) First off get a Lotus Elise '96
2) Buy these tuning parts for said Lotus:
Racing Soft Tyres
Racing Suspension: Hard
Racing Brake Kit
Fully-Customisable Transmission
Fully-Customisable LSD
Engine Tuning: Stage 3
Sports Computer
Racing Exhaust
Sports Exhaust Manifold
Sports Catalytic Converter
Intake Tuning
Stage 3 Turbo (Optional)
Stage 3 Weight Reduction
Either Carbon Bonnet
Window Weight Reduction
3) Now apply this tuning setup, leaving the transmission for the second:
Brake Bias: 3:7 or 2:8
LSD: Initial Torque: 45
Acceleration Sensitivity: 20
Braking Sensitivity: 30
4) Now do this to the transmission:
Set
Max Speed to
Minimum
Set
Final Gear to
Maximum
Set
Max Speed to
Maximum
Set
Final Gear to
Minimum
Set
1st Gear to
Minimum
(This will give you the longest 1st and reverse possible)
5) Customize Elise to your liking with aero/wheels and paint.
6) Go onto a big open track that is fairly simple (Big Willow is nice and easy)
7) Quick Settings:
Transmission: Manual
Active Steering: Off
TCS: 0
ASM: 0
SRF: Optional (can flip if you turn too hard)
ABS: 1 or 0
8) Now unplug your steering wheels power, but keep it plugged into the ps3.
9) Start the race and use the bumper cam view.
10) Turn around on the spot and drive using the rear-view mirror!
(This is easier than looking back as you don't have to hold down a button and mirror your movements!)
And a replay if you want to see it in action:
Save on a USB in the folders /PS3/SAVEDATA/
Hope this has helped a few of you, as I have had a blast doing this today!
And before you say it, I know the driving in the replay isn't brilliant but trying to drive like that is tricky to get right
