SETUP GUIDE
SETUP GUIDE
Wheel Base:
The 8IGHT-T 2.0 is equipped with the rear hub carriers in the middle. 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-T 2.0 is equipped with 2.3mm sway bars on the front and 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.
Clutch:
On new clutch bells, clean the inside of the clutch bell with scouring pad or fi ne 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 stiff er spring. Stiff er springs engage at a higher rpm and hit much harder. If the springs are too stiff , it will cause the clutch to slip.
Plastic vs. Aluminum Clutch Shoes:
We have found the four aluminum clutch setup works best on most tracks for the 8IGHT-T 2.0. But if the track is very loose, rough, and doesn’t have
jumps that are diffi
cult to get over, two plastic and two aluminum shoes allow more slip and smoother acceleration. Running four aluminum shoes
has the most punch, but isn’t as good on slick tracks. Our recommended clutch setup is four aluminum shoes with two gold springs and two green
springs. Whenever you need to rebuild your clutch, we recommend the following tips. First of all, be sure to clean all parts with Losi Nitrotec™ Spray
Cleaner (LOSA99217) to ensure there is no oil or debris on any of the parts. Cleaning includes all clutch parts including the clutch bearings. Spray
out the clutch bearings to ensure there is no grease slung from the bearing at high rpm which would cause premature clutch wear or slippage.
When reinstalling the clutch pins, do not use any type of Losi-Lok on the clutch pins. Using Losi-Lok will make it diffi
cult to remove the pins. Once
the new shoes are installed, pull back each clutch shoe 1mm to make sure they spring back to position to ensure proper movement. You will also
want to make sure the clutch bell has anywhere from .25mm to .50mm of movement and spins freely on the crankshaft. You can use Losi’s Metric
Shim Set, LOSA6356 to dial this in properly. Now that your clutch is fully rebuilt it is time to break it in. This is done by starting your truggy and
having it idle on the ground. While fi rmly holding the vehicle down, apply ½ throttle for three seconds. Repeat this three times to fully seat in your
new clutch.
Here is a layout of clutch setups ranging from softest to hardest in acceleration

Differentials:
The 8IGHT-T 2.0 comes equipped with 7000 wt in the front, 10,000 wt center, and 2000 wt in the rear diff . Thinner front diff erential oil increases off -
power steering, but if the oil is too thin the steering will become grabby and inconsistent. Thicker front diff erential oil increases off -power stability
and increases on-power steering. Thinner center diff erential has less forward drive, can unload more under acceleration and is easier to drive on
rough and slick tracks. Thicker center diff erential has more acceleration, increases on-power steering, and less off -power steering. Thicker center
diff erential is better on high bite/smooth tracks. Thinner rear diff erential has more corning traction and increases steering in the middle of the turn.
Thicker rear diff erential has less steering in the middle of the turn and more forward traction.
Shock Mounting Positions:
A more inclined position (moving the shocks in on the tower) has softer initial damping and is more forgiving. A less inclined position (moving the
shocks out on the tower) makes the car more responsive and is better for technical tracks.
