On The Street

About once every 10 years, someone comes up with a breakthrough part in the aftermarket. The Heidts bolt-in independent rear suspension could be that part for 2011 and beyond. Inboard disc brakes, and improved dynamics and ride quality-it won't be an inexpensive upgrade (it retails for $6,500 and is available for '67-69 and '70-73 Camaros), but its gonna be one a lot of Chevy enthusiasts will crave.

As you'd expect, the Heidts Camaro was one of the top two finishers in the ride evaluations. It soaked up the rough stuff like no previous second-gen Camaro I'd ever driven. Even the railroad crossing in our test failed to upset it. It's like the tracks weren't even there.

The IRS is said to be able to handle up to 600 hp and our test car was right at that limit thanks to its LS V-8 with a 2300 TVS Magnuson blower. Even in Third gear, the massive NT05s were no match for the car's prodigious torque. They painted two very impressive, very even, black stripes on the pavement.

The steering was light, perhaps a little too much so, but it was quite linear. The car went exactly where you directed it.

Where the Heidts Camaro fell short was in the brake department (the setup had no pedal travel and was unnerving on the street) and clutch travel. Once you were going, it shifted "like butta," but it was quite disagreeable trying to get the car moving.

It was so weird looking through the rear wheels and not seeing rotors, but that was the first tip off that you had a high-tech machine in your possession. The second was driving it. The only faults we could find with this F-body had nothing to do with the Heidts pieces attached to it. Nice job. - Jim Campisano
