Wheelhop, excessive body roll, and tire spin are all the result of overpowering a factory coil or leaf-spring rear suspension system. Control is what gains traction, and traction leads to faster acceleration and stability during high-speed cornering. While the factory leaf-spring suspension systems on many early Chevy muscle cars worked well for the era, suspension has evolved, making the original stuff sorely dated.

Using our F73 Camaro as an example, we wanted it to accelerate hard and take corners at greater speeds. We wanted a suspension system that's strong enough for racing yet comfortable during normal street use.

Asking for the world? Sure, but thanks to Detroit Speed we can have it. We're talking about its QUADRALink system that's completely tunable and designed specifically for '70-81 Camaros. This package features an adjustable track bar, upper and lower control arms, and optional coilover shocks that allow you to upgrade from the factory leaf-spring setup. The coilover shocks feature a custom valving for the ultimate performance and ride quality, including ride height adjustability. Overall, it's a truly one of the best setups we've seen for this chassis.

While the system is intricately detailed and well thought out, it does require careful measuring, cutting, welding, and grinding. So it's not a bad idea to enlist the help of someone with the proper tools and know-how. We turned to the crew at A&E Motorsports, who have been handling F73s since the beginning.

It's only a matter of time before our second-gen is ready to hit the streets. With our Detroit Speed suspension complete, we'll follow up this segment with the Moser 9-inch details and start putting the drivetrain and sheetmetal back together. Stay tuned-this is going to be one wild ride!
