It wasn’t long ago that we first introduced our latest canvas, an ’02 C5 Z06 Corvette, dubbed Project Twitch.

If you recall, we invited your thoughts on what direction to take our ride, and the majority of you said to kick it up a notchsome of you even took the time to include detailed wish lists. Well, we heard you and we’ve already produced a complete plan of action; of course, all of it will be covered in the coming months.

This month, we’re addressing the suspension. Bear in mind that the factory offering is pretty incredible; it’s a lot more than most people will ever be able to take full advantage of. We should also mention that if you’re into SCCA class racing, you’ll know that the C5 Zs are extremely competitive cars right out of the box, and altering from the stock stuff will generally place you in a class reserved for serious chassis cars. We have no plans to compete in a specific class; instead, we tend to participate in autocross and open-track events as an exhibition car, so that throws any class-specific rules right out the window.

When it came to finding the ideal suitor for our Z, we went with LG Motorsports (LGM) in Wylie, Texas. The folks at LGM have been in the business of racing and designing hard-core suspension components for well over 35 years and have plenty of real-world track experience by competing in everything from the Corvette Challenge to the World Challenge series to the coveted American Le Mans GT2 division.

After a lengthy conversation discussing our needs and goals, we decided to install a complete LGM suspension package, which includes the GT2 coilovers with 12-way adjustable shocks and the G1 front and rear sway bar assembly. Combined, these offer infinite adjustability, both in ride quality and setting up the ride height for every kind of driving you do. And even though the LGM components may seem exotic, anyone looking to do a similar install will appreciate just how affordable this setup really is. Priced at $2,395 (add $250 for the quiet endlinks), this all-in-one system will transform any C5 into a serious tracking machine, all while offering a plush ride for those long road trip excursions.

To outfit our Z with the LGM goodies, we headed to Motivational Engineering in Carson, California, where owner Mike Saiki handled the job in a day. The installation was straightforward with minimal effort, however, it was Saiki who recommended we complete the install by scaling the car. Even with the good stuff, it takes a well-balanced chassis to keep the tires on the ground and maximize your efforts as you traverse through any course. Follow along as we show you what it takes to transform your prized Z from a weekend thrill ride to a world-class performer.
