If you've decided to hit the drag racing circuit, don't hit the road until you've modified your suspension. Trying to drag race with a car that has stock parts won't get you very far — even if you do have a high-performance engine. In fact, if you have a high-performance engine, running on a basic suspension kit, you're asking for problems. That's because a basic suspension kit can't withstand the pressure that comes from a high-performance engine. Here are four ways that an auto shop can help you modify your suspension for drag racing.
Change Those Springs
When it comes to modifying the suspension for drag racing, the first thing you want to do is change the springs. You don't want your car lifted too far off the ground. Those added inches under your car will add to the roll, which will slow down the speed and hinder performance. To get the most out of your suspension, lower the body of your car by switching to a softer set of springs. Lowering your car will also lower the center of gravity while choosing soft springs will help reduce the body roll that can come from basic road performance springs.
Replace Your Control Arms
If you haven't replaced your control, it's time to visit the auto shop. Stock control arms don't have the stability or durability to maintain proper function during drag racing. In fact, those stock rubber control arms can cause your tires to hop along the asphalt when you reach top speed in your car. The best way to eliminate the hop, and ensure maximum capacity, is to have your mechanic replace those stock control arms with rod-ended control arms.
Install Adjustable Dampers
Stock dampers can also cause problems for your car when you're trying to enter the drag racing circuit. Stock struts and shocks may be enough for daily driving activities, but they don't have what it takes when it comes to drag racing. For maximum control when you need it, have adjustable dampers installed on your car.
Offset the Body Roll
If you're going to be racing your car, you want to make sure that you have the right amount of body roll. Unfortunately, you can't do that with standard sway bars. The first thing you want to do is have the front sway bar removed completely. That way, you get better movement from the front of your car. Next, you want to replace the rear sway bar with an anti-roll sway bar. That way, you have maximum weight transference across the car.
