SETUP GUIDE
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 o-power steering. A shorter wheelbase is better on tight or slick tracks. A longer wheelbase (spacers in
front of the rear hubs) decreases o-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 o-power traction, but has less
on-power steering. A thicker front sway bar decreases front o-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 make sure to clean the inside of the clutch bell with scouring pad or ne sand paper 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 stier spring. Stier springs engage at a higher rpm and hit much harder. If the springs are too sti it will cause the
clutch to slip.
Plastic vs. Aluminum Clutch Shoes:
We have found the four aluminum clutch setup to work 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 dicult to get over, two plastic and two aluminum shoes will allow more slip and smoother acceleration. Running four
aluminum shoes will have 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 will include all clutch parts including
the clutch bearings. We like to spray out the clutch bearings to ensure that there is no grease slung from the bearing at high rpm which would
cause premature clutch wear or slippage. When reinstalling the clutch pins we recommend NOT using any type of Losi-Lok on the clutch pins. By
using Losi-Lok on this part, it only makes it dicult 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 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

Shoe/Spring Description
Ultimately the smoothest and easiest to drive setup
Used on very loose tracks where little punch is needed
Used on loose high-speed tracks where there are no jumps out of turns
Very smooth, yet has good punch. Motor must have adequate power to pull this clutch setup
Very forgiving and reduces wheel spin with punch being sacriced slightly.
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

Differentials:
The 8IGHT-T 2.0 comes equipped with 7000 wt in the front, 10,000 wt center, and 2000 wt in the rear di. Thinner front dierential oil increases o-
power steering, but if the oil is too thin the steering will become grabby and inconsistent. Thicker front dierential oil increases o-power stability
and increases on-power steering. Thinner center dierential has less forward drive, can unload more under acceleration and is easier to drive on
rough and slick tracks. Thicker center dierential has more acceleration, increases on-power steering, and less o-power steering. Thicker center
dierential is better on high bite/smooth tracks. Thinner rear dierential has more corning traction and increases steering in the middle of the turn.
Thicker rear dierential 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
