    And you're running just the speedway coils to sit that height? I know you mention cargo coils, but that was before, correct?
    That is just the speedway springs and all new poly body bushings and poly spring isolators (in front) on the last set up. The poly body mount bushings do raise the car. Been the same way since. maybe it looks different now? dont know really.





    Here is a video with a good (current as of earlier this year) stance. You be the judge if it settled some. I believe it did.

    This is my basic understanding, there are people on here who know WAY more about this than I do, (so smarter people please correct me if i'm wrong in anyway):

    Load capacity is essentially how much weight the spring is designed to carry. The more coils, and the thicker they are, helps them carry more weight. If you had an 800lb spring, 11" high with 5 coils, it would compress farther, given the same amount of weight, compared to an 800lb, 11" spring, with 8 coils. If that makes sense. It will effect ride height, among other things. The picture of the spring in your link barely has any coils in it, so I'm leary.

    The best knowledge I have says that this makes sense to me as well. Maybe I need to re-read the sticky, and possibly some science type articles somewhere that explains how that works. Other than research, the only way to know would be to order some and see. But I'd need to find rears as well then.

    Removing and installing front springs over and over again is going to make you want to drive off a cliff. (i did it 3 times, and i did!) If you like either 87gtvic's ride height, or mine, the speedways are a cheap, proven method. Cutting 1/2 a coil off a spring is also no big deal, especially with beefed up springs. It's when you go crazy chopping off multiple coils on stock springs that you'll lower the load capacity, while increasing the spring rate, and make everything terrible, haha.

    If you really want to SLAM your ride, it can be done, but it's going to start to get expensive

    I'm also on my third set of front springs. Went back to stock. I don't want it lower, ripped a sidewall out of a tire when it sat about an inch below stock and that was enough of that. Lincoln fenders and trim do not play well with lowered suspension.

    Not seeing this coil logic. An 800lb/in spring is the rating no matter how many wraps it has. 800lbs will load it down 1" each additional 800lbs will load the spring 1" more inch. 5 or 8 coils wraps doesn't matter, these are a constant rate. Progressive spring rates are a whole different ball of wax.

    I don't know what I'm talking about but I just did a crapload of frenzied spring research on fronts this morning for the wagon project. When you're looking at the spring load rate on moog's site, it tells you the maximum load bearing weight for the spring (and has a huge disclaimer about DO NOT EXCEED VEHICLE LOAD RATING, etc). So I don't think it's 800lbs=1" compression. Look at the Moog 80090 here: https://www.moog-suspension-parts.co...il_springs.asp I settled on these because they were cheaper on Amazon that RockAuto, they were in stock, and I have Cargo Coil CC8819 ordered for the rears. They tell you the free height vs installed height. So with a bunch of comparison between the moog sedan, wagon, hpp, & p71 spring rates and installed heights for model numbers I got here http://www.grandmarq.net/vb/showthre...se-Read-First! the regular front replacement moog springs say they have an installed height of like 11.5", so those police rate+10 fronts I got should be the correct pigtail ends, size, width, height, and spring rate, but it says the car will more or less sit 11.75", if I understand properly. 1/4" raise on the front end isn't going to matter much when the rear cargo coils pop the booty on the wagon a bit as well. I know this can change as the wagon gets loaded down, BUT the CC819s are a 200 rate spring (even though variable rate means they squish then level/firm up). I'm too lazy to look up the height difference right this second.

    800 lb/in spring rate means 800 pounds to compress the spring 1". The thing to keep in mind is that is directly at the spring. The spring sits roughly half of the way between the pivot point and the centerline of the wheel so compressing the spring by 1" makes a lot more than 1" of difference in wheel travel.

    I did end up going with the speedway springs, after doing MORE research around the web of experiences with these being lowered more that that. Judge me all you want for my 'incorrect' spring rate choices of 1000 lb/in for the fronts and 300 lb/in for the rears. I believe it will achieve my desire from the springs. OF course, improved sway bars (front and add one in the rear eventually), along with new bushings all around and a wider wheel/tire setup.

    I will report back my experience with the heavier springs.

    I know nothing about the springs. I picked up mine used off of another members wagon! Hope it works out well for you and curious how it will look.

    1000/300 front/rear will be stiff. Dunno if it'll be harsh though. Definitely will be interesting.

    Stiff, definitely. If my tires had less sidewall, it would likely be edging toward harsh, has a lot more of a 'performance' feel but still doesn't ride like trash and isn't so stiff it's bouncy. I would NOT go any heavier because it would stat to get bouncy. I know the ride won't be everyone's cup of tea, but this boat doesn't float anymore.
    Handling definitely improved greatly. Still needs more grip, and better sway bars/new bushings. But that's all the supporting stuff for stiffer springs (in my eyes). So for right now, I'm certainly pleased. Gonna take some swooping turns on the interstate, since it's too long of a wheelbase for the twisties on the back roads I normally hoon the Miata on, though I did do an uphill run on those last night to make sure...
