Install a Performance Suspension on Your 1987-1993 Mustang

Most Mustang enthusiasts build up and enhance vehicle performance in stages as their budget and time allow. Unfortunately, these owners do not always take the next stage in performance from the same book as the previous stage. Too often they install the wrong parts, resulting in slower speeds, worse handling and wasted money.

Many companies have adopted the "package" concept. Some of them, such as Edelbrock, do a great job of including everything you need--from intake manifolds to cylinder heads to the exhaust for a 5.0. As well as these package systems work, however, to achieve the next level of performance, you invariably have to yank just about all the package and start over with a bigger intake, more aggressive camshaft, ported heads with larger valves, etc.

Instead of the package concept for suspension, Kenny Brown's line of Advanced Geometry Suspension (AGS) systems provide a way to do your suspension right.

You can start off with the AGS 1 system and have a budget suspension as a baseline. When you get another bonus check, you can step up to the AGS 2 system, then AGS 3 and so on, never having to remove an already installed AGS part. This makes a suspension system purchase an easy decision because you know you will never regret the money spent. So, follow along as we install a Kenny Brown AGS 3 system on our project Modern Mach.

The AGS 3 system includes Kenny Brown's Double-Cross subframe connectors, urethane bushing package, Koni struts and shocks, strut tower brace, lower crossmember brace, front lower springs, and a panhard bar kit with aluminum panhard bar. The Kenny Brown Jacking Rails, shown in the foreground, are not part of the AGS 3 system, but we decided to add these to the Modern Mach for its safety.
