They are committed to providing you with the best engineered parts you can find and Ground Up SS396.com is committed to get you what you need at the best price around! So whether it’s a restoration build, a mild street machine, or an all out race car SS396.com has you covered on the products you need!
Ground Up carries a full range of Detroit Speed products for Camaro, Chevelle, El Camino, Nova, & A/G-Body models. From Coilovers, Control Arms, and Speed Kits to their Quadralink and Hydroformed Subframe Kits Ground Up SS396.com has you covered.
The first generation Camaro front suspension design is dated compared to today’s advancements in suspension theory. One of the most important contributors to today’s advancements is tire technology. Suspension design and tire design are not independent of each other. Unequal-length double a-arm suspensions have made tremendous improvements, along with improved tire technology, and each car’s generation improved on the last.
The factory 67-69 Camaro/Firebird and 68-74 Nova experience positive camber gain on the outside (loaded) tire during cornering. This is largely due to the front suspension’s low roll center. Don’t confuse low roll centers with low roll angles. The vehicle rolls about a roll axis determined by front and rear roll centers. The roll axis pictured from the vehicle’s side view is usually higher at the rear and lower at the front for solid rear axle suspension with independent front suspensions.
The greater the distance between the roll axis and the car’s center of gravity height, the greater the roll. It works as a “lever arm”. The longer the arm, the more the car rolls. The more the car rolls, the greater the positive camber gain on the outside wheel while cornering for first generation designs. Bad news! The outside tire during cornering should ideally gain less positive camber to allow the tire to use its full contact patch.
Other areas for improvement, in addition to roll center placement, include camber and caster curves. Initial caster settings for first generation Camaros are approximately +1.5 degrees. Today’s performance cars have 2.5-3.0 degrees of initial caster. Stock Camaro caster setting is limited to additional caster because alignment shims must be used to gain greater caster. One way to improve this is to use an offset upper control arm. Higher steering efforts and greater straight line stability will be noticed.
The Detroit Speed Subframe uses Hydroformed Framerails. Hydroforming is a process of shaping tubing using hydraulic pressure instead of heat or bending which causes weak points. Using this technology we can build the strongest framerails. Along with the added strength and Corvette style handling, the subframe also adds a much-needed increase in ride quality. It uses a Coilover shock and spring suspension that was designed here at Detroit Speed.
The QUADRALink™ system lets the rear axle properly articulate during operation. It provides a better handling for the rear of the car. While using the patented Swivel Link design it functions smoothly without any binding and noise that may come from spherical mounting points on other suspensions. Not only does it provide a great handling suspension but it also increases the ride quality from the stock leaf spring suspension.
Our products are designed and built by experienced and highly qualified engineers and fabricators. They are made to provide late model performance at a higher quality. We regularly test our parts on test vehicles. Auto crossing, slalom tests, and cruising to car shows are only a few examples of the intense testing that our products go through. We also do many computer operated and indoor testing before they are offered to the public. Each part is tweaked and adjusted until it operates and fits properly and most efficiently for the specified application. We want our customers to have the same premium products on their muscle cars as we have on our own.
