Re: Advice on Front/Rear Suspension Setup
The cat5 are great but very stiff. If you intend on street driving the car, get rubber bushed leaf springs around 175 lbs/inch. Rear springs generally are horsepower related, so if you either have race tires on it, or have way above 500 hp, then you probably need the higher rate springs.
You can save money by getting circle track coils 5" diameter, 600 lbs rate, but you'd need to use the circle track "hidden" adjuster setup I have a link to on my web page.
You can also use Adco front and rear bars from Summit or Hotchkis Hollow bars.
I don't like the way the GW sub connectors hang down, but if you like them they certainly work as well as anyones.
It IS a pretty wise choice to get all the parts from the same place to insure the car is balanced in handling. I don't have a problem at all with you getting GW parts, just providing options for saving money. It is NOT guaranteed to work as well if you mix and match your parts. Even though sway bars are the same diameter, they can have different mounting bushings and materials that can alter their effective rates.
You could get by without the upper arms and just do the Guldstrand mod, or vice versa, but the extra caster the GW arms allow is very helpful to handling and extra caster reduces bumpsteer that is also problem with first gen Camaros. I'd do both if you will drive it hard.
