Modified Mustangs & FordsHow To Chassis Suspension
Independent Front Suspension - On The Fast Track
The Roadster Shop IFS kit is designed to work without the shock tower sheetmetal, offering a cleaner look and abundant underhood room
Participating in a high-performance driving event is some of the best fun you can have on four wheels. If you're of the competitive mindset (and what gearhead worth his roll-a-way full of tools isn't), you'll soon find yourself skimming through suspension catalogs looking for that "edge" you need to get the power to the ground, transfer weight, keep your tires planted, and keep your classic Mustang or Ford flat and stable through the tightest of corners. While driver experience is certainly paramount to getting around a track, good driving ability is only going to take you so far. Once you've reached the limit of your Mustang's stock-style suspension, it's time to step up and use a suspension designed with the proper track-oriented geometry, using OE-level parts for durability and reliability. Now you can have all of that in the Roadster Shop's new Fast Track IFS kit for '65-'70 Mustangs.
If the Roadster Shop is not a familiar name, don't sweat it. The company is a little late to the Mustang game, but that doesn't mean it opened its doors last week, either. The Roadster Shop has been designing Fast Track systems for a myriad of GM muscle cars, and has plenty of design and track event awards on its shelf from the company's GM-based projects, including Goodguys Street Machine of the Year. The Roadster Shop specializes in suspension components, full performance frames, and front subframe kits. Currently, the Roadster Shop offers an IFS crossmember kit--which we'll delve into shortly--and a front subframe kit that replaces everything forward of the firewall with new framerails/subframe and bolt-on suspension components.
The Roadster Shop's IFS is similar through all of its muscle car applications, with just the main crossmember width and alignment brackets specific to each car line. The suspension itself is a clean-sheet design using TIG-welded, large-diameter control arms, fully lubricated bushings, upper and lower bumpstops, and late-model Corvette spindles and sealed bearing hubs (no bearings to service, grease, and so on). The rest of the suspension features standard goodies like adjustable coilover shocks, an antisway bar, and rack-and-pinion steering. The Roadster Shop Fast Track IFS rings the register at $4,995 with an ample feature set. However, there are several available options you might want to take advantage of, including larger disc brakes, double adjustable coilovers, engine mounts, and more.

The Roadster Shop IFS doesn't ship with any brake hardware standard; however, you do have several options. You could hunt down stock Corvette parts, but you'll most likely end up rebuilding the calipers, and so on. Phil Gerber of the Roadster Shop says the majority of the IFS kits they sell go out the door with the optional 13- or 14-inch, six-piston brake kits. Also note that the Roadster Shop can re-drill the Corvette Z06 hubs to the standard Ford bolt pattern, if you already have a nice set of wheels you plan to reuse on your build.
