Has anyone tried this suspension setup? I'm looking for something a bit more than my M7 springs and stock shocks setup.

Love to hear some input... I can't even find how much they actually lower the car?

 

yes, it makes your voice vibrate on command.


it's like those auto-vibrato on karaoke machines.

 

I don't own the setup, but have driven a MINI that has the Koni Sport setup and it was much smoother than my stock setup FWIW.

 

Koni Sports are much smoother than the stock shocks. However, for the ultimate in ride quality (smoothness/softness plus control), go with Koni FSDs.

 

I have the Koni FSDs + H-sport springs installed by Central Coast Coopers. I am very pleased.

 

I'm worried about going to the FSD's because of the lack of adjustability.

Right now, way to much weight gets shifted during accelleration, and I'm looking to help that with ADJ shocks.

 

just adding Koni yellows with the M7 springs might be the way to go. I had the M7 springs with the 05 stock struts and I found the damping to be lacking; too much bounching around. I would have gone with the Koni yellows but I didn't know how the new ride height would be (some struts can change the ride height a bit), instead I got a set of Koni coil-overs (close-out, great deal)...

 

I don't know that shock absorber adjustability will counteract the perceived transfer of weight during acceleration. Presumably you are referring to the front end rising a bit during hard acceleration; the "rise" might be slightly tamed with a shock that can be adjusted, but I doubt it will be eliminated. The beauty of the FSDs is that the ride quality over rough road surfaces is much softer/smoother than with even the Koni Sports; additionally, the FSDs have much better control over the tendency of the car to roll in hard turning - it really is the best of both worlds (smooth/soft ride plus tight cornering).

 

The stock shocks are definitely prone to bouncing around. Probably any aftermarket shock would be an improvement over the stock shocks. However, for the premium (over other aftermarket shocks), I would recommend the Koni FSDs.

 

I have on the Koni Sport struts with Eibach Pro lowering springs and the ride is perfect. I have no complaints.

 

I spoke with a technician at Koni North America yesterday. He specifically recommended against the FSD's with any springs other than stock. He explained that on account of how the frequency damping works, changing the springs alters the frequency of the chassis as it traverses bumps, making the FSD's not as effective as they should be.

His suggestion was to use Koni yellows with aftermarket springs, or go with a Koni sport shock/spring kit.

The reason I called Koni is that I have H-Sport springs and stock shocks and the combination is not terrific, IMO. I am considering the new street suspension setup from Texas Speedwerks, but at nearly $2K, I'd have to try it before buying.

So, I'm still trying to make an intelligent decision on a suspension arrangement, too .

 

It's nice to hear from a manufacturer that the more expensive option may not be the best

 

My bigger complaint is the "squat" in the rear on accelleration.

Combined with the softer progressive nature of my M7 springs, I'm having issues back there right now... not M7's springs fault imperticular, but the amount of travel combined with my wide 235 tires is forcing me to reconsider this suspension setup. I do enjoy the ride 75% of the time, but the other 25% i can tell there is some dampening lacking.

 

Do you have personal experience with changing shock absorbers eliminating squat? I don't; so, before I were to swap shocks to eliminate squat, I would want to see the results on someone else's car before I pulled the trigger on the purchase of a set of shocks for that reason.

I think you may be seeing the down-side to the progressive spring design.

What about the travel combined with your 235 series tires is forcing you to reconsider your suspension setup? Tire rub? Or????

Net, net, I am not trying to dissuade you from your desire to purchase a set of Koni shock absorbers; I am a strong fan of Koni shock absorbers. It is just that I don't think the problem you are trying to solve will be solved by changing shock absorbers.

 

I've had koni yellow adjustables on another car before on stock springs, and yes it does reduce dive and squat quite a bit. Doesn't eliminate it, but it helps.

 

If memory serves, jymontoya has progressive springs (M7s). Stock springs are linear as a general rule. Progressive springs are generally "softer" for the first 25% of compression, then harder (the progressive design element). Out of curiousity, was the other car (that you had installed Koni Sport shocks on) front or rear wheel drive?

 

Yup, I used Koni adjustables on my Prelude and it helped a good bit. A noticeable difference in dive and squat.

I think you are right about my seeing the negative aspect of the progressive M7 springs.

I’m starting to REALLY understand all those comments about M7 springs dropping a little bit too much in the rear. This is becoming more and more evident as they settle. They need to be about .25” - .5” higher in the rear. I know there are strut spacers I can buy, but I’m afraid those (.5”) will be slightly too much of a lift, plus I’d rather spend that money (~179) toward new shocks. First, I’m going to try putting full sized bump stops back in their (only the rear is an issue), and see if that doesn’t stop some of the rubbing. I’ve cut away about as much fender liner that is going to help, now it’s a matter of controlling the maximum travel.

So, If this doesn’t work, I’ll be back.

 

I have a Koni Sport kit (4 koni yellow adjustable shock and Koni performance springs) on my MCS for the past 10,000 miles and we installed the same set up on over 20 minis.
Both for street or track use, for the money, there is no better set up.

What's this supposed to mean?

 

means kenchan has been on NAM for FARRR too long....

serious note.. i have koni yellows on eibach springs... good ride, although i wouldnt say its better than stock, but it feels more controlled.. on the track however its no competition, the aftermarket unit makes the car more controllable and less prone to sideway motion

 

How much do the Eibachs lower a MCS?
