Hello,

I haven't seen much about these around. I originally wanted to go for the Eibach springs but as they got discontinued (I understood...) I am looking at different solutions.

Thanks,

Vogtland aren't that popular in the Mazda realm. They are very popular with the German cars. If you are using OEM shocks, check out H&R springs.

also RSR springs

Thanks Majik,

Do you know by any chance the spring rate of these H&R (couldn't find a lot of info on the forum and website)? They seem to go even lower than the Eibach Pro (-1" vs. -1.25") but they may not be stiffer?

I actually did not know about these, the rate seems to be (very) close to the Eibach.

They seem to lower the car unevenly F:-0.8 R:-0.6. Is that even a concern (-0.2"?!?!?)

Thanks,

There has never been any real information published about the H&R springs. It was thought they were a progressive rate spring so there wouldn't be a linear spring rate to publish. They are a tried and proven spring by causal drivers as well as some track enthusiasts.

Here's a shot of a car with them:

RSR Down springs are hard to get. If you can find them, they offer a good stance with good spring rates. Between what's out there as an off the shelf spring, H&R and RSR Down springs are about the best to work with OEM shocks. If you have aftermarket shocks, the Tein S-Tech provide a good stance but they are a little too high of a spring rate IMO for OEM shocks.

I have actually just put on some Konis Yellow. I've only had my car for only 2.5 year (I bought it stock and concentrated on reliability upgrade in order to be able to track it once or twice a year) and I wanted to see what just the shock change would do to the car and after think of changing springs and/or sway bar.

I can't lower the car too much because of my shitty shaped driveway but after searching on the forum I thought Eibach springs would be the next step (but they got discontinued).

Nice pics btw.

RSR seem a good option by looking at the data (F:349 R:261). How about the Tein H tech? (I would go Tein S as per HC's recommendation but I am afraid they would lower it too much).

If it's just the curb to the driveway, you can always get one of these:

Curb Bridge

FWIW, I just go on/off my driveway at an angle to avoid scraping too bad.


Not too many people have used the H-Tech. Most people really want to lower their car and the H-Tech barely does that. If you want to spend some money, you can always put Ground Control Coilover sleeves on your Koni's. That way you can adjust the height to what you need/want.
