Ok, so if I want to stiffen up my suspension, will 64-66 GT Front and rear springs make a big difference? I know that 78-80 Granada’s had a HD suspension option, but I expect that it not very stiff. I don’t except my car to corner like a Porsche 911, but I would like to remove the jelly ride. Thanks!
I'm running 1" lowering springs from National Parts Depot, they are much stiffer than the stock front springs..
The best way to tighten the suspension is with shocks, preferably adjustable. Not to mention they are much easier to install before killing yourself changing springs. If the car sits where you want it, do shocks 1st, then springs to fine tune it. Adjustable shocks are better, but even the KYB GR2's are a vast improvement over stock. You can take care of the body roll with the ADDCO sway bars.
Is there a difference spring rating other than lbs? Does a stiff spring mean a better handling spring?
Big block springs from globel west, should make a stiffer ride, with a lil small block motor, I own a pair but yet havent put them on.
In short, No. Overly stiff springs actually hurt handling. You need enough spring to support the car and to prevent bottoming during hard manuevers and jounce but most of the stiffness in a properly designed suspension comes from the dampening of the shocks. If you want a stiff ride, get double adjustable shocks and run the adjustment all the way up to the firmest setting, it'll ride like it has no springs. Too stiff of a spring is also hard for a shock absorber to control.
If you are tuning for a race track, stiff springs can be a more popular choice. Tuning for daily driving, you will most likely want a moderate spring/ stiffer shock and combine that with better sway bars. Going over potholes, etc. , and long drives, stiff springs will wear you out. I took a two hour drive in a friend's overly-sprung car that I will never forget. Like everything else in car crafting ... don't get caught up in "if a little more is better, a WHOLE LOT more ought to be GREAT" .... it rarely is.
