The 2014 Corvette Stingray with the Z51 Performance Package has been designed and engineered to be a world-class sports car for the track. But before unleashing its acceleration, cornering and braking capability, there are several key procedures and steps that must be taken in order to properly experience its track prowess.

Once all the original bushings are pushed out and the parts cleaned up bushing installation can begin.
There are a couple of things to be aware of before the first bushing is installed. The bushing bore must be clean and free of any snags of metal that may have been raised during the bushing removal process. Powder-coat or paint may also be in the bushing bore and should be removed to ease bushing installation. A raised area, whether it be paint, powder-coat or gnarled metal, causes the bushings inner sleeve to drag on the urethane, preventing smooth suspension movement. Unlike rubber bushings, urethane bushings should rotate smoothly throughout their suspension range of motion (one of the major reasons for the change to urethane). Too much clean-up of the bores is also a concern: the bushing should require effort to push in. You should be able to squeeze your hand and force the bushings in.

Many of our 1956 to 1962 Corvette customers report a noticeable vibration or rocking at the base of their windshield. More frequently than not, the windshield mounting posts are snapped off. Over the years, many of these posts have been subjected to questionable repair work, with shims, metal strips and welding being employed to varying degrees of success. In the mid-1980′s, Corvette Central developed a permanent fix for this issue by designing a machining operation which allows the installation of steel tabs that are much more resilient than the originals. Follow along as we describe the post variations, breaks, and solutions to windshield posts.
There are two variations of windshield frame posts. The 1956-58 version has a square notch relief for the door post with the upper window stop (Corvette Central part number 281009). The 1959-62 version has an angled notch to allow for the later style door weatherstrip, which features a built-in stop and continues over the door post (Corvette Central part number 631010).

If you want to really dress up the nose of your stock C5, then adding Z06-style front grilles is an easy and inexpensive way to do it. Corvette Central offers these after-market grilles for less than $100 a pair and installing them really couldn’t be easier. In fact, you don’t even need any tools, and the whole installation takes well under a half-hour, even if you’re a novice wrench. Here’s how to do it!

The fourth generation Corvette was a radical departure from General Motors early Corvette engineering. It eliminated a perimeter frame to support the suspension and driveline. Two front frame rails integrated into the first ever Corvette uni-body construction. This made for an interesting driveline mounting installation. The front suspension subframe was bolted to the frame rails while providing engine mounting points. The lack of a transmission crossmember added another twist, with a torque arm supporting the transmission and connecting it directly to the differential. The differential was mounted with two large bushings at the outer uni-body rear frame area. Rear vehicle weight was supported by a transverse spring that bolted directly to the differential rear cover. Read more on “C4 Suspension Overview” »

Exhaust systems have improved immensely from the early years when we would replace rear exhaust, mufflers and tail-pipes almost yearly on dual exhaust vehicles. Corvettes were no exception. If they were driven infrequently with rich running engines, it destroyed the carbon steel exhaust tubing quickly. The rear of the exhaust system was most prone to damage as the moisture was blown backward and, in many cases, rarely dried up. Most of us complained loudly when engine temperatures exceeded 180 degrees, saying that our engines would not last under the intense temperature pressure. That rise in temperature along with aluminized tubing just about put specialty exhaust shops out of business. Now we come to expect that an exhaust system will last the life of the vehicle, and in many cases, it will. Read more on “Corvette Central Exhaust Systems Overview, Part I” »

There was a time when a component would fail it would require repair or rebuild. But today we throw it into the appropriate recycle pile. Growing up in the 60s and 70s sometimes makes it difficult to trash anything; today it makes more fiscal sense to buy another one. If you worked in a GM dealership in that time period, the philosophy was repair unless it had catastrophic damage. Of course back then metal was used for most components; plastics were for the occasional trim piece. One of the many repairs you had to perform at the dealership was rebuilding windshield wiper motors, distributors, alternators, starters and fuel pumps.

The Brock Yates’ One Lap of America endurance race, formerly known as “The Cannonball,” consists of a variety of challenges on the dry skid pad, drag strip, and racetrack. It is the equivalent of the Hot Rod Power Tour with track challenges at each stop. However, it is grueling because each night it is necessary to drive to the next event anywhere from 400-600 miles away, have your driving skills tested thoroughly the next day, pack up everything as soon as possible, and get on the road again. This happens continuously until the last day of the race. In addition, the entire circuit can take a team over 3,000 miles across the country, a true test of vehicles that are driven hard on the track and then subjected to a few hundred miles on the highway for a week straight.
