I'm very familiar with what it takes to do a coil-over conversion. I've just never been in
a mustang with coil-overs.
I do not want a softer spring in the stock location, that won't help ride quality much, plus the springs I have are too soft as it is.
Allow me to explain: The stock spring acts against the frame and the LCA. Due to the placement, the wheel rate is approximately 25% of the spring rate. Also, the LCA bushing causes some bind and transfers alot of NVH through the vehicle due to the load it carries.
In a coil-over application, the spring acts directly on the spindle, which then acts upon the end of the A arm. In this case, your wheel rate will be ~90% of the spring rate. The softer spring will allow the wheel to react faster to road irregularities and the position will cause less bind (force) on the A-arm bushings, reducing NVH.
To properly locate coil-overs, a 4 bolt caster/camber plate is necessary. A good one, like from maximum motorsports or griggs. A person may get more road noise
from CC plates, but the ride will be smoother
from the improvement in geometry that coil-overs give you.
You can get a better ride and
better handling in a mustang by switching to coil-overs. Coil-overs must be done properly to avoid damage to the strut towers and I recommend parts from www.maximummotorsports.com
My question is/was, has anyone riden in a mustang with coil-overs with street oriented spring rates.
