Would you like to improve your car’s traction and braking system so that make your driving more comfortable? There is an easy way to make it by yourself instead of going to mechanic shop. And all you need is basic tools and some knowledge.
If you have a rear wheel drive car with coil spring rear suspension, in most instances you may have what is called upper and lower control arms
holding your rear axle under the car. The control arms support the pinion angle of the rear axle and prevent your axle housing from being twisted when accelerate or decelerate. The pinion shaft in the rear axle is placed at a nearly horizontal position in the housing. When people position the pinion angle towards the ground by a few degrees they may have considerably improved the grip for more accelerating.
A shortcoming of installing control arms by turning the pinion shaft towards the ground is that you may lose some of your rear braking power. Since the fact that your rear axle has been turned by a few degrees over center in the wrong direction and may hinder effective braking, it may cause your rear axle to slid or jump under heavy breaking. However, when the pinion angle is turned up away from the ground you may increase your rear braking power by a bit but lose traction for heavy acceleration, so it is important to identify your driving habit before start doing the job, then you may find the right control arms for your car.
Because people are always looking for rear control arms with more traction under acceleration than braking, so they might think that a minor loss in rear axle braking is alright to be ignored. However from what we have been told by previous experiences, we concluded that people would never like to drive the car too fast to be stopped. So make sure you have strongly improved the braking system, control arms and any other parts that guarantee your safety on road when drive a bit faster. Because we have all heard about this saying before, "Speed doesn't kill; it is the sudden stop that usually does it!"
