I realize this subject has been posted to death, but I'm struggling with it.
Context: for the past 5 years I've been driving an M2 with Bilstein Sports, H&R springs and huge anti-sway bars. A very stiff, hypertense ride.
Now I've got a bone-stock '71 1600 with a serious case of the roly-polies and I love it. The ride is magnificent. It swallows bumps the size of small countries like they're not even there, but the way it rolls around turns, it's more like coming about in a daysailer than a car. It personifies the term swanning around in a tidy 5 foot by 13 foot package.
So, some of that I want to keep, but lowering the center of gravity a bit would be a plus. I'm adding 2002 anti-sway bars (1600s came without), so that should solve some of it. Bilstein HDs will replace the KYB Gas-a-Justs and 185-70/13s will remain, but the big question is this: how much will the soft, luxurious ride (seriously) that I've come to love in this car be lost with addition of shorter springs?
If so, how much? I would trade off a little for flatter cornering, but much of the character of this car centers around its nonchalance. It's quick in its own lazy way, but it's no athlete. More of a competent, but non-competitive type. Is there such a thing as a short, soft spring? I'd rather not install the HDs and springs twice to find out the difference.
