I personally had the Espelir springs that were very similar to the H-techs and had a similar problem. The front had drop of 50mm and the back dropped 20mm. When I packed the ride, the rear sagged and tucked in under the wheel well.

Other people here had this problem even with no load and to help resolve this, they used the wagon springs with a much higher spring rate so the rear wouldn't sag. But since you've already got springs, I don't think you want to that route.

I wound up replacing the original shocks with Koni's and the springs out with megans some of the stiffest springs you can buy. You can probably also run the mazdaspeed6 springs and shocks since they were designed for a much heavier car. I think there was a another thread about somewhere here

 

what your looking for is a "raked" look. from that picture you posted, your car is actually sitting level...look at the side skirt height. however, if you look at the wheel wells then the car looks like it's sagging.

there are 2 ways to get the look you want:

1) buy coilovers. that's the easiest and best way to get an adjustable ride height.
2) buy 2 sets of springs..one that drops the front X amount and one that drops the rear Y amount. in your case, you want X > Y.

IMO, just go coils.

 

Hello,
I have been running the tein H tech springs for a little bit and have a question about them.
the reason that i went to the new springs is to get the stiffer ride also to level out the car. the ride is better, but still not what i am looking for.

what i am looking for is a supenison that will not have the back of the car lower then the front of the car. also it does not help when i have people in the back, it make's the rear go down to far.
i can think of two fixes for this, thought that i would let you guys hear what i am thinking and see you can give me a better idea.

1. ( i dont think this one can happen) for trucks you can buy "pucks" to put in between the coil and the body to give you a lift. do they sell those for the mazda?
2. buy some nice coil-over shocks that replace the stock shocks. this will make it a little stiffer and maybe lift it a little bit. this is the one that i am thinking about. if there is some of these out there which ones do you think that i should get?

thanks for your help[/b]

Couple of things:

1 - your car does not sit lower in the back. Actually it looks like it has a slight forward rake. The larger gap between the front tires and the fender well than the rear is an optical illusion that makes you think the rear is lower.
Take a carpenter's level and set it on your door sill. I'll bet you see a nice slant toward the front (bubble will go toward the higher end of the car, or the rear).

2 - Yes, you can buy rubber spring spacers that will prevent the coils from collapsing further under loads. They don't "lift" as much as preventing the spring from compressing more under loads. Downside of this idea is it increases spring rate a LOT, as you now have effectively made the affected coil a solid block with no compression. They're basically "universal" parts that fit particular diameter springs, not car model specific.

3 - Coil-overs will allow you to adjust ride height to your tastes, but any decent quality ones (there's a fair amount of cheap junk out there, basically you get what you pay for) are going to be expensive.

4 - And yes, you can mix & match spring brands to get the ride heights you want. That gets a bit expensive too, as springs are sold in sets of 4 so you're going to end up with 4 springs that you won't use.

 

thanks for getting back to me about my car.
the one idea that sounds good to me is the idea of using the wagon springs for the rear (mixing the different springs). does any one of pictures of the tein h tech or racing beat wagon springs on the rear of a sedan like mine? if they do can some one send me the picture of it. i want to know if it will raise the rear end a lot higher, or if it will make it so the fender gap looks the same.
also how much stiffer will the ride be, or if it will be the same but just sit alittle higher?

Well, if you decide to go that route I think I can offer a suggestion that might make it easier for you and help both of us out. You have a 6s, correct? If you buy the wagon spring set, I'd be willing to take the fronts off your hands. We can negotiate on the price. That should give you what you want and seeing as I've been considering experimenting with the Mazdaspeed front springs it will let me do that without having to buy a set of four to get just the fronts.
I don't believe the wagon/hatch springs will stiffen the ride anymore than the regular Mazdaspeed sedan springs will, they're just cut a little higher to compensate for the aprox. 100lbs heavier rear weight of the wagons and hatch models.

Let me know (PM is probably best) if you decide to go that route, I'm definitely interested in the MazdaSpeed front springs.

 

Eibach makes the wagon springs for the i4 and the V6. I've had the i4 wagon springs on my i4 hatch for a couple of weeks and the wheel well heights are identical. The car has a very slight raked look if you look at the side skirts.

 

Im having the htech springs installed next week too. And thats been my concern all along in attempting to get similar if not identical wheel wells. I believe the htechs and if not the sportlines by eibach are the some of the only springs ive found with a big enough offset to get that look we're trying to get.

I guess im wondering if the Koni's that ive bought along with it will make the spring ride just a tiny bit higher.. during load and without. Im assuming yes but ever so slight.. perhaps not?

You running stock shocks now right Hobbit? How's ride comfort by the way? I know the htech spring rates are similar to stock so i bought front and rear sways to hopefully get it up to par.. just hoping the ride quality is there, from what i gather around the forum it is.
