2010 Chevrolet Camaro SS: Suspension Walkaround
Found this link . . . good read.
http://blogs.insideline.com/roadtest...alkaround.html By Dan Edmunds | March 23, 2010 http://blogs.insideline.com/roadtest...mb-717x478.jpg I'm tired of unintended acceleration. I want to get back to talking about acceleration that is fully intended (and appreciated) and the cars that are built to manage it well. What better way to take the automotive equivalent of a Silkwood Shower than a suspension walkaround of our 2010 Chevrolet Camaro SS? Let's get right to it, shall we? http://blogs.insideline.com/roadtest...mb-717x477.jpg Up front, there's a coil-over MacPherson strut. http://blogs.insideline.com/roadtest...mb-717x477.jpg But the lower end does not have the single L-shaped lower arm that most strut suspensions have. Instead, there are two lower links (white), each with its own ball joint, just like the closely-related Pontiac G8 GT. The front stabilizer bar (green) connects to the strut body via a long, slender link (yellow) for a 1:1 motion ratio. http://blogs.insideline.com/roadtest...mb-717x477.jpg Like most cars with north-south engines and rear-wheel drive, the Camaro's steering arm (yellow) acts ahead of the axle centerline. The hub carrier it attaches to (white) is aluminum, unlike the Pontiac G8, which uses one made of steel. http://blogs.insideline.com/roadtest...mb-717x477.jpg Here's a closer look at the dual lower links and their ball joints. The forward one (yellow) comes in from above so that the steering arm can sneak past underneath. http://blogs.insideline.com/roadtest...mb-717x477.jpg Them's some big brakes - much bigger than the 2-piston sliding calipers found on the front of our dearly departed G8 GT. These calipers (green) are 4-piston fixed units from Brembo. A clump of mass-damping weights (white) have been unceremoniously stuck to them (where they don't show much), presumably to quell a resonant vibration. The ventilated rotors (yellow) are 1-piece cast units. http://blogs.insideline.com/roadtest...mb-717x476.jpg Out back, the rear multi-link suspension looks very, very similar to that found in the G8 GT. Like the Pontiac, "multi" in this case means three links and one L-shaped upper arm. Two links (green forward, red aft, behind the shock) make up what amounts to a lower wishbone. The fully boxed upper arm (white) curves off behind the shock to meet its hidden second pivot. A toe-link (yellow) keeps the wheel pointed in the right direction. http://blogs.insideline.com/roadtest...mb-717x477.jpg Here's a snail's-eye view of the lower links and their wishbonesque arrangement. http://blogs.insideline.com/roadtest...mb-717x477.jpg Left to right (and bottom to top): forward lower link (yellow); toe link (green); and upper arm (white). The forward upper pivot of the upper arm, a pillow ball, is just barely visible. The rear pivot is a higher volume rubber bushing that's hidden off behind the spring and shock. http://blogs.insideline.com/roadtest...mb-717x477.jpg The rear lower link does quite a bit of work as the spring/shock assembly and the stabilizer bar connect to it. The shape is slightly different from that of the G8 GT, but it's very close. The stab bar motion ratio looks about the same(0.4:1), but the spring/shock motion ratio looks a little smaller (0.7:1). http://blogs.insideline.com/roadtest...mb-717x477.jpg Like the front, the Camaro's rear knuckles (yellow) are made of aluminum. Those of the Pontiac G8 GT are steel. They also house ginormous 4-piston fixed Brembo calipers of an open design for easy pad swaps and an external crossover tube (black) to send fluid to the outer pair of pistons. http://blogs.insideline.com/roadtest...mb-717x477.jpg That'll do. http://blogs.insideline.com/roadtest...mb-717x477.jpg Front tires: 245/45ZR20 (103Y), weighing in at 63.0 pounds Rear tires: 275/40ZR20 (106Y), weighing in at 67.5 pounds. |
nice find some good info and pics.

Very informative. Thanks for the info!

You made a valuable post to a link that gives a good overview of the ZETA II suspension. If you found the material interesting I think you will enjoy these two threads.

Great article. However, I was a little disappointed when I took off one of my wheel and saw "Made in China" on my "Chevrolet".
|
is this the same and/or similar to the v6?
|
Thanks for the info!
|
Keep the lessons coming!!! Super Cool Stuff!!
|
thanks for taking the time...now to replace 90% of it with aftermarket parts!
|
Nice, my second homepage post.
