If you like to drive your car, we mean really drive it, then you have probably noticed that the stock front suspension is just a little lacking in the area of firmness and quality of road feel. If you’re lucky enough to own a first- or second-generation Camaro, we found a way for you to upgrade that stock suspension, and get the handling you deserve.

The chassis comes with Viking double-adjustable coilovers, and Ridetech triple-adjustable units or JRi shocks are optional. Although not designed for use with an air ride suspension, it appears there is available room.

Speedtech Performance has been manufacturing suspension parts for years, so when they wanted to improve their already proven subframe offerings, they were in for a challenge. For that reason, they invited veteran racer and chassis-builder Ron Sutton to the party. According to Sutton, “We needed to achieve optimum front dynamic roll center for any suspension strategy the customer wants to run.”

Using computer modeling and simulation software, every aspect of suspension geometry was plotted, calculated, and tested. The heart of the ExtReme subframe is the newly-designed ATS spindle. The spindle will accept all brakes systems designed for the C5 and C6 Corvette, and comes standard with stronger C7 hubs and bearings. Roger Maniscalco, vice-president of Speedtech, said, “Our spindles are forged from 7075 aluminum, and feature mountings for C5 or C6 brakes.”

The tubular upper control arms are constructed from mandrel bent .120-inch thick wall DOM tubing. All components are laser-cut, and TIG-welded, and come assembled complete with 304 stainless steel cross shafts. The upper control arm is adjustable to allow 7 to 9 degrees of camber angle.

The sway bar is a splined unit, and different bars are available depending on the driving style you plan to pursue. Unlike conventional subframes, the Speedtech unit utilizes a Sweet Manufacturing race-oriented rack-and-pinion steering.

The frame itself is made of box-welded steel that is gusseted with tab-through-frame connections for added torsional rigidity. Did you notice the angular cuts in the frame by the control arm mounts? That is the design feature that allows the use of tires that are up to 315 mm wide. Finally, you get up to 30 degrees of steering angle that retains a 100 percent correct Ackermann angle, with no bumpsteer.

There are a few things that we do want to let you know about. First is that the installation requires a steering column change. Speedtech has all the information you need to let you know which aftermarket steering columns fit the application. Next, the chassis is only designed to accept LS engines. At this time, traditional small- and big-block engines will not fit.
