Droop: is the amount of suspension downward travel from ride
12
height. Always measure the droop of the L8IGHT with the shocks
on the model. Measure from the center of the top shock mount
to the center of the bottom shock screw, (photo 12). More droop
(travel) in the front will have more on-power steering and allow
the L8IGHT to roll more across the rear when on throttle. More rear
droop will increase off-power steering and allow the chassis to roll
over on the front while off-power.
Ride Height: is the level of the chassis above the track surface as it sits on its suspension. As the chassis sits on a flat surface measure
up to the bottom face of the chassis. The LOSI LOSA99173 Ride Height Gauge is ideal for accurately setting and measuring this. For
your base line you will want to adjust the front of the chassis with 20mm of ride height and 20mm in the rear. We have found the
L8IGHT handles best when the front ride height is 1mm to 2mm lower and no more than level with the rear of the chassis.

Shock Pistons: Shock pistons are available and marked with different size holes that control the flow of the shock fluid as it moves up
and down with the suspension movement. If you look closely you will see the hole size (54, 55, 56) molded into the pistons. Note that
the larger the number the smaller the hole size. Using pistons with smaller holes (#56) provides stiffer damping, slower weight transfer,
and slower response. Pistons with larger holes (#55 & #54) provide softer damping, increased traction, quicker weight transfer and
response.
Shock Fluid: is graded by its viscosity or thickness. Lighter fluids are lower numbers like 20 and 25
weights while heavier fluids are larger numbers like 35 to 50 weights. Lighter shock fluid will give more
overall traction and allows quicker response to suspension movement but also has a tendency to allow
too much chassis roll in the corners. Heavier fluids have less overall traction and react slower but on
high bite and smooth tracks, heavier fluid tends to be easier to drive. Heat makes shock fluids lighter
and cold makes them heavier. Make sure you adjust shock fluid when there is a drastic temperature
change (20-25 degrees) to maintain the same dampening. If it gets cold you will need to go to a lighter
weight shock fluid. If it gets hotter you will need to go to heavier weight shock fluid.
