Remember this Camaro? Sure you do. Throughout the 2006 magazine year, this orange '69 Z/28 became quite a regular project in Super Chevy magazine. Anyone who followed along may remember the "Back To The Future" and "Backside Bolt In" tech article installments that ran in the February, April, May, and October issues.
If none of this rings a bell, let's recap some of the wrenching and parts that went on this F-body. First and foremost we searched and found a stock Camaro with OEM style wheels, brakes, and suspension components (tires were radials). We were eager to see what kind of numbers we could achieve with a stock Camaro. Before it went under the wrench, we thumped on it at California Speedway in Fontana, and recorded the results. Our testing at the Speedway consists of a 420-foot slalom, a 60-0 mph deceleration test. As optional tests, we also employ a skidpad, which measures the g-forces a vehicle can pull, and quarter-mile acceleration.
After the baseline tests were completed, the Z/28 went straight to our tech center for the upgrades. The front and rear clip upgrades are as follows:
- A new set of Heidts' tall 2-inch drop spindles. The tall spindles have a re-engineered upper ball joint, which adjusts the vehicles camber's.
- Heidts' upper narrowed tubular control arms and lower tubular control arms.
- Hellwig's narrowed sway bar complete with bushings.
- QA1's adjustable performance coilover shocks.
- Wilwood's 12.9-inch rotors, Wilwood's "Dynalite" four-piston calipers (front and back), and a new Wilwood master cylinder.
- 17-inch Boyd Wheels with a set of ground grabbing Nitto N- 01s.
- Heidts' parallel four-link rear clip kit, complete with subframe connectors.- Currie 9-inch rear end and axles, with Randy's Ring and Pinion third member.The April and May 2006 issues covered the front subframe upgrades and track testing.
The rear four-link installation was covered in our October issue, and there were never any follow up numbers-until now. You can well imagine over the years we've had the chance to test a variety of Chevrolets on the track. We are pleased to announce that in the slalom tests, (drum roll please) this particular Camaro has out performed all the vehicles we have tested thus far making it the "King of the Hill." Let's take a look at the new slalom numbers and deceleration numbers shall we?
Our driver ran times of 6.00 seconds then 5.90 seconds, 5.85 seconds, and then finally a record setting 5.84 seconds through the 420-foot slalom. The stellar result can be attributed to the great parts from Heidt's and the NT-01s from Nitto, which are essentially race tires for the street. (It should be noted these tires are not recommended for use in the rain.)
As for the braking, you can see from the graph that the Wilwood brakes worked a pretty consistent set of stopping distances. 60-0 mph measurements are 125.97 feet, 121.60 feet, and 121.90 feet. The 30-0 measurements are 28.74 feet, 28.33 feet and 27.02 feet. These are pretty impressive when compared to the OEM equipped 60-0 stopping distances of 201.7 feet and 197.39 feet. Wow.
