without the swaybar at least one wheel will stay planted to the ground.
has anyone tried running without the front swaybar on the team magic?
Roll Bars are secondary springs that are used only during cornering, and are used for fine tuning the balance of grip created by the roll of the vehicle. In many cases with RC cars they are not needed unless you cannot get your car stiff enough in the corners while keeping it from bouncing down the straights. Or you are having a problem with a tire lifting off the ground. If you are having a problem with a tire lifting put a roll bar on the opposite end of the car.
Touring car or road car roll bars are the simplest form of roll system. The system usually consisting of one bar at some diameter that connects to both the left and right suspension arms. When the suspension raises or lowers equally on each side the bar has no effect on the suspension of the vehicle. When the car rolls into a corner the bar has two effects the first effect is that the suspension gets a little harder on the outside of the vehicle due to the torsion affect of the bar. The second effect is that the bar will lift the inside tire off the ground which will level out the car and reduce the pressure placed on the outer tire. The leveling effect is what makes this system work.
This system works on the premise of reducing grip forces to equalize the balance of a vehicle. Due to the reduction of grip philosophy the use of this system can be out of place and cause more reductions than gains. The biggest gain that this system can make is to keep all four wheels on the ground.
When the suspension is set soft while cornering, a vehicle will have the tendency to dive under heavy braking and or squat under hard acceleration. When the car dives under braking, it can lift up the rear inside tire. This lifting of the tire is reducing a whole tire worth of grip through cornering. To get that tire back on the ground would be a big gain. To do this you would use a front anti roll bar. Using the front anti-roll bar to fix the problem on the rear works because of the nature of the system. Since the roll system lifts the inner tire to correct the roll of the car it also sets the rear inside tire closer to the ground or adds pressure at the rear. If the front roll bar lifts the inside tire enough (reduces outer front grip and roll) the inside rear tire will be placed back on the ground. Hard acceleration in a corner can have the same effect as hard braking but the exact opposite. The front tire will lift instead of the rear, putting a rear roll bar will correct this.
Once the larger problem of tire lifting is solved then you use the roll bars on the front and rear to achieve the correct roll to provide the optimum pressure to the tires that are being used. You can however limit the roll to much and this will reduce grip on the tires taking you out of the optimum settings. This type of roll system affects the ride height of the vehicle so compensations may have to be made in the straight line set-up to compensate.
Hope it helps
