Ah that is right....I must have made that up.
Also that little blurb you copied out of that website would suggest that the ride would be harsh on a stock suspension with even a aftermarket spring, yet thousands of Mustang owners run Eibach Pro kits and similar setups on the stock suspension. If you cut a stock spring it will become stiffer(just like an aftermarket spring).
What is going to go wrong on a moderately cut spring? I implore you to tell me? Suspension bind or stacking? Only if the spring was cut damn near in half.
The option may not be what she wants at all but to call it non viable because of one sentence that doesn't even refer to the cutting of a stock spring is ludicrous.
I would assume you are against running Fox 4cyl front springs and Fox 90/10s on a SN95 or New Edge car too then?
