Coilover shocks are standard in most forms of competition. The QA1 Hal Proma Star GT shock is a direct replacement for the fourth-generation Camaro's shock/coil spring assembly. The aluminum-bodied shock features 12-way adjustable dampening, while the adjustable spring perch allows fine-tuning of the car's ride height. The shocks came with all of the hardware and a set of powdercoated springs.

Twenty-five years ago, you weren't cool if your ride wasn't jacked up. Gabriel Hi-jackers were the hottest shock on the market. And a simple install, which included routing a few small airlines coupled with a trip to the nearest air compressor, was all it took...and up you went, instant hot rod celebrity status! Of course, there were inherent problems to go along with the new image, such as the loss of a comfortable ride, lack of all performance handling capabilities (not to mention the extreme body roll around corners) and, of course, the watchful eye of the law! Boy, how times have changed.

Today, the hot scene in street cruising has taken (excuse the pun) a dip in the other direction. It's about getting your ride as close as possible to terra firma without sacrificing all drivability. Not that lowered cars are a new idea, mind you, but instead of examples such as classic early Impalas and Biscaynes (as most hot rodders remember being the stereotypical lowriders), these days you can find virtually anything with four wheels pushing the limits of ground clearance to new lows. But there's still correct-and incorrect-ways of accomplishing the goal of lowering your ride.

Extremely popular right now are the plethora of the air suspension systems being offered by a host of well-known companies. These setups, which we've done a couple of good stories on recently, seem to give you the best of both worlds: the ability to drive at a more tolerable ride height, while being "slammed" when sitting still. But when it comes to true canyon carving performance, most air bag systems were not designed for this type of action.

Prior to replacing the stock-type shocks with the Proma Star GTs, we installed a set of stock coils on Bilstein shocks. This is roughly where the ride height was for our '96 Z28 with the stock coils.

It's relatively easy to lower a car's stock suspension (and basically screw up all of the handling and comfort characteristics at the same time). For the front (and some rear suspensions), simply taking a cut-off saw or a torch and hacking away at the coil springs will-though its not always the best way-get the job done. If there are leaf springs out back, a trip to Pep Boys for an aluminum lowering block kit will easily (and safely) eliminate the rear's altitude problems. (You'll find versions ranging from 1 to 3 inches of adjustment.) On the other hand, you can do your homework, decide how you want the car to handle, and order the correct springs and sway bars from companies like Eibach, Hotchkis, LG Motorsports, and others. Then, perhaps most importantly, choosing a good shock absorber that will ultimately enhance both the ride and handling characteristics of your lowered car will give you the best of both worlds.

Recently, we set out to reevaluate the suspension on a lowered '96 Z28 Camaro that we've featured here before. The car has a host of top-line parts (Hotchkis bars, LG Motorsports control arms, and Eibach springs, to name just a few). In it's most recent incarnation, the late-model F-body had an almost perfect stance, with only a small gap between the top of the tire and the bottom of the wheelwell lip at both ends. Wouldn't it be cool, we thought, to see if we could gain adjustability of the ride height and still maintain (and perhaps enhance) the suspension's dampening? (And test the limits of ground clearance, knowing we could always raise it back up again?)

Enter the engineers at QA1 Hal Shocks. Known for extremely well-built and engineered dampers for virtually any application, the company had recently been advertising a setup for the fourth-generation Camaro that we thought would be perfect in allowing us to control the ride height of the car's front end, while at the same time giving us the ability to adjust for track conditions and severe dampening needs. Furthermore, since the car was already lowered, we thought that if we were to measure the actual length of the shock needed while the car was at its ride height, maybe we could find a shock with a shorter body and still have one that had some compression left. (In most lowered situations, dropping the suspension without going to a shorter shock stresses the shock's damping ability since it takes away almost all of its stroke.)
