Stan;

That's a pretty impressive suspension system, but I wonder what wheel/tire setup you have which can take advantage of it? Unless you have 6 inch wheels and (at least) 70 series rubbers, you really can't make use of all of that nice suspension stuff. Also, The ride must be pretty darn stiff...in my opinion, too stiff for everyday use...and if you cut away your suspension snubbers, and then bottom out, be prepared for more extensive repairs.

IMO, progressive / lowered springs can wait. I suggest you first install those Bilsteins with the original springs, but definately add front and rear ipd anti-sway bars. Also 6 inch wheels with 195 or 205/70s. I think you'll be impressed. As I wrote above, that is a good setup for everyday, but if the roads where you are don't have potholes, and you really want optimal handling, way cool appearance, then you could consider the spring upgrade. Just beware...if you combine that with even lower aspect ratio tires, you won't be able to drive over a painted line without rattling the fillings out of your teeth...not to mention the extra stress on that steering box.

Cheers
