Differential Setup

Anti-Roll Bar
There are three differentials on the B8RS: one for the front, one for the center, and one for the rear
of the car. The effects that the diffs have in the handling of the car are noticeable; they can alter
the way a car handles bumps, exits a corner, and accelerates. As the B8RS differentials are
adjustable and pre-assembled in the factory with neutral setting, you can always make the diff
setting slightly tighter.
Front Differential
You can alter the amount of steering by altering the diff oil weights in the front diff. If you want
more steering entering the corner, try running lighter oil, such as 3000wt. More off-power steering
will be generated as well. Also, lighter oils are better for bumpy conditions. Heavier oils will give the
car better on-power steering. If the oil is too heavy, it will make the car oversteer in the rough or
rhythm sections.
Basic Setup: Front #5000 wt
Center Differential
Running lighter oils in the center helps the car track straight while accelerating (such as
3000~5000wt), but reduces acceleration out of corners. Heavier oils in the center (such as 7000wt)
will give the car better acceleration. However, for really bumpy sections have lighter oil in the
center will allow the car to accelerate better and straighter.
Adding an anti-roll car, or stiffening it, reduces traction at that end of the car. Therefore, it feels like
the opposite end has more grip. As anti-roll bars reduce body roll in turns, so they make the car
feel more direct, and make it change direction quicker. Normally, different thickness of anti-roll
bars are used to adjust the setup.
Basic Setup: Front #7000 wt
Basic Setup: Front 2.3mm Rear 2.7mm
Basic Setup: Rear #1000 wt
Rear Differential
Lighter oil in the rear diff gives the car more off-power steering, but may make the car feel
inconsistent around the track. If the car is not consistent, you can try to adjust the setscrews on the
rear diff to make the diff tighter.
