    KYB are a longevity upgrade to the OEM stuff. I have the monotube shocks on the rear of my Volvo - good stuff. I also have the GR2 on the front of the Mazda5 and they are holding up very well.

    the mazda 5 shares suspension components with the smaller Mazda 3 which is why they wear out so quickly.

    DO NOT purchase lowering springs if you are buying stock, OEM struts. dont even bother with OEM. buy bilstein b4 if you want OEM style, and bilstein b6 with eibach lowering springs if you want a nice coilover -type upgrade.

    KYB vs KONI FSD vs Bilstein B4? Which would last longer?

    bilsteins without a doubt. hell, they are going to last longer then your current original suspension, let alone Koni's.

    if you want to lower your car a little bit and improve handling/body control, I recommend bilstein b6 with eibach lowering springs all around.

    bilstein > koni without a doubt

Lastly the like of Koni or Bilstein are usually valved to accommodate a bit of sport application thereby giving them a little tightness on street use and likewise with a lowering springs such as the H&R.
    this is correct.

    since you know your stuff, I will tell you that bilstein is better then koni, and Eibach springs are better then H&R.

    So GJ,
    Are you a Mazda master-tech? You really seem to know a lot, maybe even everything, about these cars.

    90210, when I went Koni on the V70, I made the choice based on reports of harshness on the part of Bilstein. They have a reputation as performance shocks. Of course, that was before there were B4s, so it may be a different game now, but from what I understand, the B6s are hard because they are real road/track struts. Lots of compromise on the street so they can take be effective on the track.
    IMHO, the Mazda5 already feels a bit thin in the suspension department. Added harshness wouldn't do it for me, at least.
    The only reason I am bringing up the FSDs is because they are engineered vastly different than any other shock. They are not monotube, so that harshness is gone, nor are they like most twin-tube because they respond gently when jarred, but firmly when pushed more softly, like cornering. Everyone who has some has spoken very highly, and without a doubt, they will be my next shocks on whatever vehicle they will fit.

    I am not a mechanic no. Just an avid Mazda and bmw enthusiast.

    Yes, the B6 struts are aggressively valved but still compliant. Think of it as a firm ride without being way too harsh. How much of a ride height drop you get, and how harsh the ride is depends more on the springs rather then just the strut. If you get a good pairing in there (for example, eibach springs go very well with bilstein) then the car will ride nice regardless.

    Bilstein are still “Street” performance at the end of the day so expect some compliance. Eibach is meant to mix street compliance with good handling, so all together it will be a nice pairing even if you’re looking for a comfortable ride.

    The general consensus over at the BMW forums was that Bilstein > than Koni in terms of longevity. I have a BMW 5 series, and that thing rides more comfortably then the Mazda. Someone at bimmerfest posted a review of his experience using the Bilstein b12 kit on the car (b6 + eibach springs together for cheap) and said that the car rode very nice and articulated over bumps better then stock even on rough canadian roads, while others say that they are harsh so opinions are subjective regarding this matter.

    Again, I DO NOT have FSDs, just heard over and over again how good they ride. Do some research and get some testimonials before you pull the trigger. I AM looking forward to my first set tho.
    Now here's my big thing: My suspension and brakes have saved my tookus many times, and my parent's neglect of components like suspension parts has gotten me into a lot of trouble. I have truly come to appreciate predictability in emergency maneuvers. Lost my truck b/c it was not only big and lethargic, but because I was waffling on keeping it or getting rid of it, so the suspension and brakes were not up to snuff. Couldn't save it in an emergency maneuver. Now, I actually buy cars with shot suspensions because I save money and I know that after the refresh, it the car will handle as good as showroom or better. Don't skimp on those parts. This stuff is often life-or-death.

    if you are looking for very good suspension, you can't go wrong with Bilstein b6 and eibach lowering springs. you will be very pleased with this setup.

    the bilsteins will be a very good choice indeed. your only other option would be coilovers, like BC racing for example makes good suspension. you can adjust them to yield a soft ride yet it will corner more flat and better over stock.

    Huh? How do you figure that?! I'd never say any of those brands is better than the other... they're all top level suspension companies.

    BC makes an OK suspension setup for the money if you're not picky about high precision damping or being serious at the track, but they're pretty low on the overall scale when it comes to coilover suspension. The BCs that fit on the 5 are universal cartridge coilovers. They work ok for what they are, but their damping qualities aren't made specifically for the 5 (or 3) compared to true coilover setups with threaded bodies and valving set specifically for that car. That's why the BCs and similar universal cartridge coilovers have so many adjustment steps- they have to make sure that a range that works for the cars those cartridges might be used in will exist and be useable for that car. That said, I was happy enough with the BCs on my 5, even though the droop travel was severely compromised, the plastic isolators were throwaway items, and the lock collars wouldn't stay put without loctite. Easy fixes.
