CAT L1 Evo Manual

Moving the front wishbones backwards offers more load transfer when loading up the front
going into the corner. This will promote more steering in general as there is more pressure
over the front wheels. This change also means the drive shaft angle has increased, so
naturally gives the car more drive. But all of that comes at the price of bump handling.
A softer damper setup would be used in this case.
The middle hole on the front shock mount is the most widely used position.
Moving the shock to the outer position will make the car react faster and increase
the initial steering response, it may however stiffen the suspension which may
require an oil and spring change so that the cars suspension feels the same.
Moving the shock to the inner hole will soften the suspension, slow down steering
reaction and make the car smoother on bumpy tracks. Again you may
need to alter the oil and spring combination to get the suspension to feel the same.
The middle hole in the wishbone is the standard setting for the lower shock absorber mounting.
Moving the shock absorber to the outer hole increases the reaction of the steering as well as
increasing the suspension stiffness, this position may cause the car to have a little too much initial
steering. Using the inside hole will soften the suspension and will probably need spring and
damping changes to make the best use of it. Anti roll bars are a good tuning aid when using
different shock absorber positions on the wishbone.
The middle hole works best for most track conditions giving good traction and drive through the
turns whilst maintaining good stability over the bumps. Moving to the outer hole on the wishbone will
decrease traction but will allow the rear to free up more in the turns. This setting would usually only
get used on high grip tracks and when moving the shock out you may have to change the oil and
spring settings to get the same suspension feel.
If the grip level is low and the track is bumpy, try the inside hole with a harder spring and a thicker oil.
The usual team setting for static rear camber is 1°- 2° negative at ride height
(the top of the wheel is leaning inwards towards the car). Decreasing the static
camber will generally increase the mid corner steering, whereas increasing the
static camber usually makes the car smoother to drive by reducing the steering
response.
For dirt tyres with a flatter profile use between 0.8°- 1.5° to keep the contact
patch more consistent.
Angling the top of the rear shock forwards 3mm will help jump landings with the sacrifice
of bump handling, it also increases initial steering.
You will need to fit a longer ball stud and add washers to do this.
