SETUP GUIDE
Differentials:
The 8IGHT-E 2.0 comes equipped with 5000 wt in the front and center di, and 2000 wt in the rear di. Thinner front dierential oil increases o-
power steering, but if the oil is too thin the steering will become grabby and inconsistent. Thicker front dierential oil increases o-power stability
and increases on-power steering. Thinner center dierential has less forward drive, can unload more under acceleration and is easier to drive on
rough and slick tracks. Thicker center dierential has more acceleration, increases on-power steering, and less o-power steering. Thicker center
dierential is better on high bite/smooth tracks. Thinner rear dierential has more corning traction and increases steering in the middle of the turn.
Thicker rear dierential has less steering in the middle of the turn and more forward traction.
Shock Mounting Positions:
More inclined (moving the shocks in on the tower) has softer initial damping and is more forgiving. Less inclined (moving the shocks out on the
tower) makes the car more responsive and is better for technical tracks.
Ackerman:
A long Ackerman plate will have smooth o-power steering and is more forgiving. The long Ackerman plate will have more steering on-power. A
short Ackerman plate responds quicker and has more steering in the middle of the turn. A short Ackerman plate is better suited for tight technical
tracks.
Camber:
More negative camber in the front has more steering and is more responsive.
Less negative camber in the front will have less steering and will be smoother.
More negative camber in the rear will have less rear traction, but will increase on-power steering and will be less grabby in bumps. Less negative
camber in the rear will have more rear traction and make the rear of the buggy stay atter, but if traction is lost it will be more violent. To ensure
your 8IGHT-E 2.0 has the correct camber we recommend using our Losi Camber Gauge (LOSA99172).
Gearing:
The stock gearing for the 8IGHT-E 2.0 is 15 tooth pinion with a 45 tooth spur gear. This gearing is recommended to be used with a 4S LiPo. If a 5S
Lipo is desired, gearing must be reduced down to 13 tooth pinion (LOSA3753). If you are running on a very large sweeping track a 16 tooth pinion
(LOSA3756) is recommended. See gear chart below for other KV rated motors and their recommended gearing.

Battery Selection:
Team Losi Racing recommends using a Losi 14.8V 5000mAh 4S 25C Lipo (LOSB9864) with the 8IGHT-E 2.0 with its respective gearing. Generally with
a 4S 5000mAh LiPo in the 8IGHT-E 2.0 we have experienced up to 13 to 15 minutes of runtime however this varies with track size and the amount of
traction that is available. An 18.5V 4000mAh 5S 25C LiPo (LOSB9834) can be used to increase overall power however a lower gearing is required. On
small indoor tracks we have found that a 5S LiPo with a 1300KV(LOSB9420) motor geared at 13 tooth has oered good power with great drivability.
Outdrives and Traction:
When your 8IGHT-E 2.0 is new it will have a lot of chassis roll and be a little loose on throttle due to lack of friction in the out drives and crossbones.
After about 45-60 minutes of running, the 8IGHT-E 2.0 will gain traction and stability. Once your 8IGHT-E 2.0 is broken in, replacing the out drives
and crossbones with new parts will have more corner speed.
Bump steer:
Running the bump steer ball down you will have smoother steering in the middle of the turn. With the bump steer ball up, this will increase steering
in the middle of the turn.
Rear Squat:
The 8IGHT-E 2.0 comes with three degrees of anti-squat. Running less anti-squat will have less o-power steering and roll (side to side) more on the
rear. Less anti-squat will accelerate better in small bumps. More anti-squat will have more support (side to side) and be better on rough tracks with
big jumps.
Ride Height:
Measuring from a at surface to the bottom face of the chassis, adjust the front of the chassis with 27mm of ride height and 29mm in the rear. We
have found the 8IGHT-E 2.0 handles best when the front ride height is 1mm to 2mm lower or at least level than the rear of the truck. To measure
your ride height properly we recommend using the Losi Ride Height Gauge (LOSA99173).
