The first test with the newly installed QUADRA Link system was the slalom run. We laid out the same 420-foot course that consisted of six turns 70 feet apart, and amazingly most of the original tape markings for the cones were still in place from our last trip to the site; this was really going to be a true comparison test! The VBOX data acquisition system used GPS to calculate the distance, time, and miles-per-hour when running the slalom course. If the DSE claims hold up and the QUADRA Link helps reduce roll and hold the road better, we should see a significant improvement in speed. As the Camaro ran the slalom, it really appeared to run much more nimbly through the cones than it did with the old leaf spring suspension. There was a noticeable reduction in body roll while it sliced through the course much more smoothly. We made several passes through the slalom to acquire an average number, and the analysis showed a significant improvement in speed, running the slalom with an average speed of 58.39 mph with the QUADRA Link as compared to 55.55 mph with the old rear leaf spring suspension! Quite impressive.
Next, we were onto the skidpad test, which measures the car's road-gripping ability. We ran the Camaro as fast as possible around the circumference of a 125-foot-diameter circle at the limit of the car's traction and grip. The VBOX measures the lateral g's the car is able to withstand. Once again, the improvement in lateral acceleration capability of the QUADRA Link was evident both visually and in g-force number. The car had less lean and the g-force increased from 0.81g's to 0.84 g's.
The final test of the day was the standing quarter-mile. We made a few passes to measure how well the QUADRA Link launched off the start. From the decrease in elapsed time and the increase in speed, it was evident that the energy from the 383 Mouse was transferred to the pavement much more efficiently, and wheelhop was non-existent. The Camaro gripped the pavement much better. The elapsed time improved from 15.16 seconds to 14.28, and the speed increased from 98.62 mph to 101.22.
There you have it, Detroit Speed and Engineering and the QUADRA Link rear suspension upgrade came through with flying colors. The improvements in handling and performance should impress any serious First-Generation Camaro enthusiast who really enjoys driving hard. The QUADRA Link is affordable and relatively easy to install (the installation instructions are very clear and easy to follow), and the improvement in ride, performance, and handling, we believe, proved worthy of being considered for addition to any cool First-Gen machine.
