The name Cusco is synonymous with high-end, well-made performance parts. Even though we don’t often see Cusco parts on U.S. soil, when someone has them, people seem to recognize the parts immediately. Cusco specializes in many specific aftermarket automotive parts, but this month we’re going to get a firsthand look at the ins and outs of installing a six-point Cusco cage into a Nissan 240SX.
We’ve already tempted and teased our readers with a behind-the-scenes tour of the Unique Performance Shelby continuation cars—the GT 350SR and the GT 500E (Ford Builder, Mar. ’05, page 67). Many of you probably lust after one or both of these cars, but not all of us can afford to purchase one yet. And because of their limited numbers, their prices do, unfortunately, put them out of reach of many of us Ford enthusiasts. That’s the bad news. But there is good news; don’t assume that because you cannot buy a genuine continuation Shelby, you can’t build a car that drives just like one. Unique Performance sells not only the cars as complete packages, but they understand the situation quite clearly and have made available many of the individual parts and assemblies used to build their cars.
Maximum’s design replaces the upper control arms with a torque arm and a Panhard rod, each of which has only one job rather than two. The Panhard rod centers the axle from side to side, and the torque arm controls pinion angle. Assigning each of these duties to separate components allows each piece to be better at its one job than the stock upper control arms are at either job. The torque arm is essentially a three-link design, and Maximum claims that it improves traction so much that after installation you may have to alter your sway bars to prevent understeer.
Although modifying a car to handle well can often seem like a black art, virtually every aspect of handling comes down to three things: the weight of the vehicle, the traction generated by the tires, and the distribution of weight on each particular tire at a given moment.
The Specialty Equipment Market Association (SEMA) Show engulfs Fabulous Las Vegas annually. It brings together the biggest names in the automotive world to show off the latest and greatest, whether it’s new products, amazing custom builds, or the newest trends. TheAutoBuilder is excited to be in the thick of it all.
If you have spent any amount of time working on street machines, you are well aware that “bolt-on” parts do not always bolt right on. Still, it’s often a lot easier to modify those parts than to fabricate your own. The same holds true for such items as rollcages. Nobody pretends that a prefab cage is going to drop right into place without having to trim a single tube. That’s mainly because the economies of scale dictate that manufacturers make a single design fit as many cars as possible. Unfortunately, a cage that fits many cars probably fits no car perfectly.
These are great days to be a muscle-car enthusiast. Performance parts are plentiful, new stampings to replace rusted sheetmetal are regularly popping up, and GM’s crate motor program makes it easier than ever to drop in a new power plant that combines incredible power with everyday drivability. Old Camaros or Novas have been passed over because they were saddled with a wimpy six. Now, however, they are the perfect candidates for a heart transplant, namely, in the form of Chevrolet’s marvel of horsepower engineering: the LS1 engine.
