SETUP GUIDE
SETUP GUIDE
Front and Rear Adjustable Hinge Pin Braces:
The 8IGHT 2.0EU is equipped with adjustable front and rear hinge pin braces. The adjustable hinge pin braces allow the angle of the pins on the
front of the vehicle to be adjusted for more or less kick and on the rear of the vehicle for more or less toe-in, and more or less anti-squat. The charts
below show the hinge pin insert orientation to acquire different setups.
Front Toe:
You never want to run toe-in on the front of the 8IGHT 2.0EU. Front toe-in (longer steering rods) decreases steering response entering in the middle
of the turn but increases on-power steering. Toe-out (shorter steering rods) increases steering response when entering the turn and increases
straight line stability, however, it decreases on-power steering.
Rear Toe-in:
The 8IGHT 2.0EU kit setup is with 3 degrees of toe-in per side. Less rear toe-in increases the wheel base of the buggy and decreases forward
traction, but increases top speed and side traction in the middle of a turn. More toe-in increases forward traction, has more off-power steering and
less side traction. This is adjusted by the adjustable hinge pin braces with the different inserts included with the vehicle. See the table under the
“Adjustable Hinge Pin Braces” in this section.
Front Kick:
The 8IGTH 2.0EU comes with 0 inserts in the front and rear. This is a very neutral setup. Increasing the amount of kick has more off-power steering,
but decreases on-power steering. Increasing the kick is recommended for low-grip tracks. Decreasing the amount of kick has more on-power
steering, but less off-power steering. Decreasing the amount of kick is recommended for high-grip tracks.
Rear Squat:
The 8IGHT 2.0EU comes with three degrees of anti-squat. Running less anti-squat has less off-power steering and rolls (side to side) more on the
rear. Less anti-squat accelerates better in small bumps. More anti-squat has more support (side to side) and is better on rough tracks with big jumps.
This is adjusted by the adjustable hinge pin braces with the different inserts included with the vehicle. See the table under the “Adjustable Hinge
Pin Braces” in this section.
Wheel Base:
The 8IGHT 2.0EU kit setup is a long wheelbase. A shorter wheelbase (spacers behind the rear hubs) increases on-power traction, rear weight
transfer, and has more off-power steering. A shorter wheelbase is better on tight or slick tracks. A longer wheelbase (spacers in front of the rear
hubs) decreases off-power steering, is more stable, better in bumps, and has more on-power steering.
Sway Bars:
The 8IGHT 2.0EU kit setup is with 2.5mm sway bar on the front and a 2.3mm sway bar on the rear. A thinner front sway bar increases front off-power
traction, but has less on-power steering. A thicker front sway bar decreases front off-power traction making the steering smoother entering the
turn, but has more on-power steering. A thinner rear sway bar increases rear traction and decreases on-power steering. A thicker rear sway bar
increases stability in the middle of the turn and increases on-power steering. Thicker sway bars are more stable on high-speed, high-traction tracks.
Pistons:
Generally smaller hole pistons, #56, have stiffer damping, slower weight transfer, slower response, and lands large jumps better. Larger hole pistons,
#54, have softer damping, increased traction, quicker weight transfer/response, and bottom out easier off large jumps.
Shock Oil:
Lighter shock oil has more overall traction and responds quicker. Thicker oil has less overall traction and reacts slower. On high bite/smooth tracks,
thicker oil is easier to drive. Make sure you adjust oil when there is a drastic temperature change (10º-12ºC) or (20º-25ºF). If it gets cold outside you
need to go to lighter shock oil. If it gets hotter outside you need to go to thicker weight shock oil.
Shock Caps and Foam Bladder Compensators:
The 8IGHT 2.0EU is equipped with vented shock caps and foam bladder compensators. The vented shock caps allow the shocks to remain
consistent by dissipating pressure as it increases from increased temperature changes. Also included with the 8IGHT 2.0EU are foam bladder
compensators used between the bladder and the vented shock cap. The foam bladder compensators provide a more responsive feel to the vehicle.
We advise that if you choose to not run the foam bladder compensators that you use non-vented shock caps (LOSA5420).
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:
The long Ackerman plate has smooth off-power steering and is more forgiving. The long Ackerman plate has more steering on-power. The 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.

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, you will increase steering
in the middle of the turn.
Ride Height:
Measuring from a flat surface to the bottom face of the chassis, adjust the front of the chassis with 24mm of ride height and 28mm in the rear. On
high-speed tracks the 8IGHT 2.0EU handles best when the front ride height is 2mm to 3mm 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).
Engine Installation:
• Step 1: Before tightening the four engine mount screws, you need to tighten the gear mesh.
• Step 2: Place a piece of paper between the Clutch Bell gear and Spur gear, slide the engine
pinching it between the gears, snug the engine mount screws.
• Step 3: Rock one gear back and forth slightly while holding the other one steady. Check the
gear mesh all the way around the spur gear.
• Step 4: Once engine alignment and gear mesh are correct, tighten the screws. Re-check the
gear mesh to ensure the engine mounts did not move.
Tuning the Engine:
Should be done following the manufacturer's instructions.
To Shut Off the Engine:
Simply use the included pipe plug. Losi also makes a tuning driver with a built-in plug for the pipe (LOSA99167).
Clutch:
On new clutch bells make sure to clean the inside of the clutch bell with a scouring pad or fine sandpaper to improve the break-in period. Softer springs
engage at a lower rpm and have a smoother power band. If the engine doesn’t have enough low-end power try running more preload (spring with more
angle) or a stiffer spring. Stiffer springs engage at a higher rpm.

Can be used with motors that have great bottom end
Good all around setup. Best compromise for punch and mileage
Increased punch with slightly less mileage
Increased punch, good for jumps right out of turn, with average mileage.
Very aggressive with great punch, engine will run hotter and shoe life will diminish
Most aggressive, maximum punch. Use with motor that has very low bottom end

Clutch Rebuild Tips:
Whenever you need to rebuild your clutch we recommend the following tips.
• Clean all parts, including bearings, with Losi Nitrotec™ Spray Cleaner (LOSA99217) to ensure no oil or debris are on any of the parts.
• We recommend NOT using any type of threadlock on the clutch pins when reinstalling, this make it difficult for next reinstall.
• Once installed, pull back each clutch shoe 1mm to make sure they spring back to position to ensure proper movement.
• Ensure clutch bell movement of .25mm to .50mm and spins freely on the crank shaft. Use Losi’s Metric Shim Set, LOSA6356 to dial this in.
• Break-in: While firmly holding the vehicle down, apply ½ throttle for three seconds. Repeat this three times to fully seat in your new clutch.
