KONI FSD's for the FRS or BRZ?
 

I don't know how interested the community would be in KONI making their FSD Shock available for the FRS/BRZ/GT86, but I personally think it would awesome. I have had them on two of my BMW's and absolutely loved them. One set on stock sport springs, the other on an Eibach Pro-kit. I prefer good coilovers and know their are great comfortable setups. However, with having to take the Wife's opinion and comfort into consideration (not to mention budget) I think this would be a great option for a lot of owner.

Would anyone else be interested in these shocks if they were available and would work with lowering springs?

KONI's How Does It Work (for those not familiar with them)

In standard shock absorbers the main damping characteristic is defined by the oil flow (I) going through the piston assembly.

Combining it with the FSD feature, KONl added a special valve which is able to control a parallel oil flow next to the one going through the piston. This parallel oil flow (II) is closed by the FSD feature, giving a rise in damping force almost linear to the time that the piston is moving in one direction.

Put simply: the FSD feature is a hydraulic amplifier that delays the build up of pressure. One could say that an extra tuning option has been created in order to get the best possible combination of handling and comfort. Since it is an integrated part of the hydraulic valve system inside the damper, no additional cables, sensors or any other electronic devices are needed to operate an FSD damper.

FSD is the simplest and most economic way to significantly improve the ride and driving characteristics of every car. Certainly in comparison with costly systems which work on the basis of computer technology, complex electronics and sensors.

I have them on a Mazda3 and they work very well. I would buy them if they were available for the BRZ (riding on OEM springs).

Any updates on these? My co-worker just brought them up... never even know Koni made FSD (I was going to get the Yellow's).

Very interesting how they work.

Soft when you want, firm when you need.

Funny I missed this thread. I am a fan of these as well and have been hoping they would be made available for our platform.

My only problem with the FSDs, and why I chose the yellows instead for my last car, is that Koni only sells them as a set. One blows, and you are SOL while it's off getting rebuilt.

I absolutely love my yellows! Great control and adjustability.... Nice and stiff!

Mark@Stillen, were you able to acquire FSD's for the FT-86 platform?

I put a set of fsd's on a car 5 or so years ago.

eh, they were nice, but nothing to go crazy over.

I run them on my GTI. They are ok, I can't really tell if they are an improvement over stock or that they are so good that I don't know if they are working at all. :D

Exactly,

I had them on a gti (07) too, and had access to a completely stock one (08) that i could drive back to back on the same mix of rural roads, (rough, spirited).

Outside of lowering the 4x4 status of the 06/7 years there wasn't enough of a difference to justify the $700 paid for the spring/strut combo (neuspeed springs).

it is a variable dampening shock that self adjusts based on whether you're riding on smooth or bumpy roads


you "not feeling a difference" is precisely because it is different. Because over rough roads they adjust to become soft, so they feel like OEM. If you were to hit the track or smooth roads, they would tighten up and give you better high speed control.

My laziness is exactly why I got the FSD's on my GTI. Having to adjust the Koni Yellows was going to drive me batty trying to figure out what was the perfect setting for either the track, autox, or daily driving.

The FSD's were more install and forget them.

They said there is not enough demand for them at the time being.

I personally noticed a big difference on my E46. My best friend who was test driving a ZHP drove mine after and noticed a difference in ride quality.

I think it's a matter of what cars really actually can't just "add stiffness" to improve handling. Our cars actually have a pretty nice ride from the factory and a pretty conservative setup. (except for the ridiculous difference on the FR-S for front/back spring rate ratios.) But cars like the WRX, and some BMWs IMO can't necessarily be lowered a ton on top of the sport package- the ride is already kinda ... unforgiving. The install and forget aspect is BIG compared to coilovers. Just install with some moderate springs and bam. done. I'd buy them. I have yellows on my NA miata, another car that has a ton of room to improve, (you almost can't make the suspension WORSE without being a fool.) Aneeehoooo. I'd be in just sayin, just for saving time and hassle. If I do coils it'll be an all out, LCAs, tophats, mounts, ends, sway bars etc. Too much.
