TUBULAR UPPER ARMS
I've recieved a fiew comments that my info is "good" for other cars. For sure a Nova or such would be very very similar to a Camaro since it uses the same subframe and components, even the firewall and some of the floorpan is the same!
I have even heard of non-GM people getting some good tips from here. I think any car would benefit from most of the improvements I have info on. While cars ARE different most can benefit from improved parts and geometry in a similar way.
I'd rather have you post your question on the Team Camaro suspension forum section http://www.camaros.net

This article tells how Penske built the car, all the suspension mods.
This 69 Camaro is still winning Vintage Races!
HERE IS THE SMOKEY YUNIK CAMARO PAGE
Any consideration of the available options needs to address the basic requirements of the owner.
You need to ask yourself the following.
How much do I want to spend?
Do I want a really neat looking suspension that is "trick" and everyone will want to look at?
Or do I want to make my Camaro handle well and I don't want to spend a lot of money on "showy" suspension?
Do I want to do irreversable modifications that will be difficult or impossible to change back?
Do I prefer stock parts that are easy to replace, or custom aftermarket parts?
Do I want maximum cornering and performance at the expense of ride comfort?
Do I want a Pro Touring, Stock, or Vintage Racer, drag racer/pro street Look?
The stock suspension can be upgraded by a few mods
that will enable it to perform nearly as well as a First Gen Camaro
equipped with an aftermarket front subframe. By that, I mean the
driver will make far more difference than the type of subframe. The stock sub is limited on
front tire width and won't be able to clear large tires like an
aftermarket sub, giving them an advantage in that area that you can't
If the stock suspension is not upgraded, only mild street performance handling can be expected.
When it comes to pure cornering power, the main factor is tire construction, compound, size and grip. It is impossible to corner at 1G when the tire is only capable of .9G Simply, you can't get more out of a tire than it has to give.
The purpose of a high performance suspension is to provide the tire with the rigidity, geometry, and stability to get the most out of it. The rest is up to the driver, the road surface, and the weather.
A high quality aftermarket subframe can save you some weight and
will almost always increase torsional rigidity, which will improve steering response and
front traction. You can gain header clearance, and can clear wider
tires than a stock subframe can handle. My Art Morrison front Subframe is 2.5" narrower each side compared to stock.
I don't believe there is a big difference in the weight of the bare subframes, I think the main difference in weight savings is centered around the bolt on suspension and steering components, etc.
Tubular A frames, are available for the stock subframe, as long as you don't want to go super wide on tire width.
A stamped steel lower A frame only weighs 11 lbs! This means there
is only a little room for weight savings by using tubular A arms, or
aluminum Corvette parts. Most of the aftermarket sub weight savings is
in what you bolt to it, not in the subframe itself. There is a GREAT
improvement in engine access, it's much easier to work on.
So, if you have pondered the above and feel you want the
aftermarket subframe- great! I think you will enjoy it once you get
it all together and running. You will have something to show to
people that is different from other Camaros and have that
last bit of better handling over the other guys. If you have the
largest rear tires, you need front tires one size smaller, if you have
a 335 rear tire, then the front needs a 315, if you use a 275 up front,
then the car will understeer and you will have quite a bit of work to
do to get the handling balanced.
If your budget is a little tighter or you like a more stock Camaro, you can still have fairly good handling and cornering power, and hopefully save some money too, but either way, it's going to cost you. Front tire width will be limited to a 255, and with some work perhaps a 275 will clear but it won't be easy. You have to do ALL the tricks to a stock sub to come close to an afermarket subframe.One additional note: Stock subframes use tapered roller bearings that will deflect and cause brake pad knock back when used with non-floating calipers. Most high perf calipers are fixed mount. They work best with Corvette ball bearing "unit bearings". So look for modern front bearing units for the best braking setup. The rear should be Corvette unit bearings, or Floater axles.
If you have decided to improve your existing First Gen suspension, You can fix what's wrong quite easily and end up with a car that will corner like a race car.
I know what is wrong with the stock suspension, and I know how to fix it, and have most of the parts. I've paid my dues to learn about suspension and read and collected Camaro handling articles since 1966!
I feel I need to add something here. While I have a good understanding of suspension and can outline what should be done to a First gen Camaro to improve it, don't take my comments as a put down of the suspension upgrade kit makers.
I feel you will have the best results if you buy a good kit and
use all the parts from the same source. That way you will hopefully
wind up with properly balanced handling. Some kits are more
aggressive with spring stiffness and will ride rougher than others.
Some cost a lot more. Just realize that if you decide to mix and
match your suspension parts, you will need to understand and be able
to tune your suspension to get it where you want it. A good kit will
have all the pieces that work together. Just because one anti-roll
bar looks the same as another it may not be the case! Little things like sway bar bushing material makes a difference.
Not enough / any negative camber gain under bump or roll.
Guldstrand mod or add more negative camber to static
setting. Or tall upper ball joints.
Springs and sway bars too soft.
stiffer springs - stiffer front and rear bars
A frame bushings deflect under hard cornering.
Global West Delrin bushings or poly bushings Greaseable Delrin is best, Polyurethane squeaks and grabs.
Ride height too high.
Cut springs or use adjuster, stiffer springs required to keep from bottoming.
Subframe bushings to unibody allow flex, -poor torsional rigidity. This get's more noticeable as you stiffen the suspension, and drive harder.
Solid subframe bushings, don't use poly bushings here, sub and unbody should be "One"
Steering too slow.
Use 80's Z/28 TA or IROC box 12.7 to 1, or get a correct year box upgraded by Lee or AGR
Firstgen Camaros can have a bump steer or "Roll Steer problem. It can be worse after doing the Guldstrand modification.
Check it first, don't assume you do, or don't have this problem, fix is special tie rod ends with longer stud, or heat and bend the steering arm down. More positive caster helps reduce bump steer.
Tires and wheels too narrow (if stock size)
Use an early 70's Corvette Rally wheel 8" if you can on a stock look Camaro. Better tires make a HUGE
difference in "stick" 18" wheels are the way to go these days if you want the best results.
Shock Absorbers too soft.
Ride Tech, Bilstein, Koni,
Lack of disc brakes on most Camaros.
Seee my brake page
Single leaf springs rear, lack of staggered shocks - 67 model.
Match spring rates to horsepower of engine, and overall
traction. I prefer the three leaf Hotchkis or Global West
type springs with no added traction bars. Ride Tech Street Grip are nice on a driver Camaro.
Tie rod ends are very low, will contact wide tires, this
is very limiting on a 67 Camaro, an 8.5" rim is about max,
255 tire. 9" wide and above need aftermarket sub!
You need an aftermarket subframe!
If your Camaro is lowered a lot, you may need to shorten the front end link sleeves a little. Ideally, the sway bar arms would be level when going down the road. But on a lowered car, the arms wind up at an angle and it can even put the links in a bind and hold the front ride height up a little. The bind in this case is in the sway bar end where the endlink bushings are.
You can't allways shorten the link sleeves to where the bar arms are perfectly level because it would then limit the side to side and front to rear travel arc of the endlinks and cause bind that way. You have to find a compromise where it isn't too bad either way.
First gen Camaros have more trouble with this because they have such short sway bar arms. I'm looking for some good photos of this to better illustrate the problem. DON'T over-torque the end links if you have poly bushings, this can cause a bind if the angles are not perfect.
(assumes "Guldstrand mod" is done)
IN ALL POWER STEERING EQUIPPED CASES, USE AS MUCH POSITIVE CASTER AS YOU CAN ACHIEVE UP TO 5.5 DEGREES POSITIVE. TRY SETTING 7 DEG POSITVE FOR AN AUTOCROSS CAMARO. MORE CASTER HELPS TILT THE WHEEL TOP INWARD WHEN CORNERING, HELPS REDUCE BUMPSTEER BY LOWERING THE TIE ROD ENDS. MANUAL STEER CARS WILL REQUIRE MORE EFFORT AT HIGH CASTER SETTINGS, YOU MAY HAVE TO USE LESS.
