Rear Squat/Anti-Squat (photo 5), is the result of suspension geometry that mechanically allows the rear of the chassis to dip under
acceleration (squat) or fight the tendency to do so (anti-squat) and actually rise on acceleration. This can be changed using the pivot
pin supports. The L8IGHT Race Roller comes with two degrees of anti-squat.
Camber: (photo 6), is the attitude of the wheel and tire in relation to the ground or flat surface.
As seen in the photo this can be measured using the LOSI LOSA99172 Camber Gauge a fuel can
or similar item that stands upright next to the tire. If the tire leans in at the top it has negative
camber, and if it leans out at the top it has positive camber. The camber link controls the position
of the wheel and tire as it moves up and down through its suspension travel. Camber has a
tremendous effect on how the tires react and provide grip on the surface you are running on.
Front Camber Links: More front negative camber on the outside (right) wheel produces more steering and is more responsive. Less
front negative camber will have less steering but will be smoother. To a point more front positive camber on the inside (left) wheel
will give better steering into and out of a turn. Less positive camber will similarly smooth out the steering but be less responsive. The
lower camber link location on the shock tower (photo 7), (Hole #4 as seen on the setup sheet) has more camber gain which is the total
camber change through the suspension travel. Running the camber link in the lower hole will increase off-power steering and make
the vehicle more aggressive - however you may lose some consistency. More camber gain is good on small tight tracks. We have found
that running less camber gain in the front suits the car the best for consistency and steering balance. A longer front camber link (photo
8), (hole #2 as seen on the setup sheet) will make the L8IGHT feel stiffer. This will keep the chassis flatter with less roll and increase
high-speed steering. A short front camber link (photo 8), (hole # 3 as seen on the setup sheet) will allow more chassis roll and make the
vehicle more aggressive but lack steering under acceleration. If the front link is made too short it may make the vehicle feel twitchy.
Rear Camber Links: More rear negative camber will have less rear traction, but will increase on-power steering. Less rear negative
camber will have more rear traction and make the rear of the L8IGHT stay flatter, but if traction is lost it will be more violent. You will
notice that the L8IGHT uses positive left side camber and negative right side camber to provide optimum traction. The lower camber
link locations on the shock tower (#4 & #5 as seen on the setup sheet), have more camber gain. Running the camber link in the lower
holes on the shock tower will increase corner speed and allow the buggy to sit on the rear more when on throttle. The upper camber
link locations work better on high traction surfaces and improve stability. Using a longer rear camber link (photo 10), (#1 as seen on
the setup sheet), will have less roll and improve stability and traction. A shorter rear camber link (example: position #3 or #8, as seen on
the setup sheet) will allow more chassis roll and increase steering on entry but will also loosen up the rear and may make it unstable.
Running in the A or B position (as seen in the setup sheet) in the rear hub will generate more corner rotation entering the turn
allowing the car to turn into the turn easier and increase steering on exit. Running in the C or D position in the hub will be more stable
entering the turn but still increase the steering on exit.
Less Anti-Squat: will produce less off-power steering and allow the chassis to roll (side to side)
5
more across the rear. Less anti-squat will also tend to loosen up the rear under acceleration on
the oval.
More Anti-Squat: will produce more roll resistance (side to side), increase steering in the middle
of the turn and have better rear traction under acceleration.
NOTE: Besides using the fixed rear pivot mounts (LOSA1746, 1747 & 1748) to alter the anti-squat
and toe-in the more advanced oval tuners will want to try the LOSA1754 front and LOSA 1755
rear independently adjustable pivot mounts so that different settings can be made from one side
to the other just like the full size race chassis.
