Track Settings Front Toe Toe out Toe in The team generally run 1° toe out, this will be the best setting for most track conditions. Adding slight toe out will increase initial turn in. 0 toe will make the car more reactive on the exit of the corner. Front Camber Positive Camber Negative Camber The usual team setting for static front camber is 1°- 2° negative at ride height (the top of the wheel is leaning inwards towards the car).
Track Settings Front Wheelbase Options 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.
Track Settings Rear Camber Link The rear camber link position can be changed on the rear camber plate and on the rear hub. You can lower the ball stud on the camber plate as well as using the different hole positions. Lowering the ball stud by adding washers increases grip/traction and removing washers decreases traction. For carpet tracks the team will raise the ball stud and run 1mm or even 0mm under the ball stud if the rear end is too locked in and they want to free the car up.
Track Settings Rear Wheelbase Options The CAT L1 Evo has 3 wheelbase options at the rear, short, mid and long. This can be adjusted by repositioning the kwik clips on the outer wishbone pin.
Track Settings Gear Differential Geared Diffs can give different driving characteristics. The handling of the diff is tuned by changing the oil. A recommended starting point is 12,000 cSt (CR229). Recommended option oils would be 10,000 cSt (CR222) and 7,000 cSt (CR221). Running two gears will give more drive and off power steering. Use 7,000cSt on high grip tracks, if you start spinning a wheel on power, go up on oil until it stops. We recommend changing the oil more often when running 2 gears.
Track Settings F.A.B. The front adjustable brake (F.A.B.) should be set tight with a small amount of slip to stop the car loading up the front too much and causing grip roll. As you loosen the F.A.B. you will get more initial steering but reduced braking. Topdecks Using the thicker front and rear topdecks (U7409 - CAT L1 C/F Front Topdeck 3.00mm and U7410 - CAT L1 C/F Rear Topdeck 3.00mm) will give more steering and make the car more reactive. The team use the 2.
