Here is the IS-F with a set of ISS Forged FS-20 Sport Compact Series and the Tein CS

I had the EDFC controller installed as i did my suspension change from stock to Tein's SCs. I must say that the ability to adjust firmness of the suspension just adds another dimension to the car in terms of versatility and also comfort. For example you can adjust the settings from 0 - very firm to 16 softer and slightly more bouncy.

To me, this was an essential upgrade. And all my passengers agree.

incredible! they look just right for the F. its clearly a great option, and i like the controller option to adjust the setting. for those who think the M3's adjustable setting was the single factor in choosing that over the F, i think this EDFC controller might sway more towards the F now.

Great shot janoy! (the other one though.... lol)

As for the ride quality. Well i have had the car back for all of two days and its a beast nice and low. The ride is a little stiffer then stock but coming from my STi track setup its still streetable to me and not bad at all. Hell the GF didnt complain about it so it passed that test.

ok this is probably a question for many but surprised no one has asked yet...

For us BCR coilover owners who are UNHAPPY with the 12k/10k springs rates and NEVER was told we can pick, I'm in the market for a new coilover setup that was specifically designed for the IS-F's heavier v8 engine.

What are the spring rates on the Tien?

How do they compare vs. the BCR and KWV3's?

Those two answers would help us determine what to switch to....

Spring Rate

kgf/mm,lbs/in
Front = 12/671
Rear = 10/559

To be honest I don't have experience with BCR and KWV3's on the ISF so I cannot really make a fair comparison. Maybe someone else can chime in!

Stiffer than stock is okay... but the real question is... does it eliminate the bounciness of the stock suspension?

anything that has adjustable valving and the correct valve for the oscillation of the spring should be able to help with bouncy feeling. to be honest the ISF suspension is awesome. i wish it would have an adjustable setting like the M3 for sport which stiffens it more.

I do like the ISF suspension in most cases but there are those times when it just breaks my back and makes my passengers fly and this makes me sad. I too wish it had adjustable settings because then it would have the ability to deal with more situations.

I would have to agree with you. Just wish there was a way to tone it down for the rear seat passengers.

NICE....looks like some real quality stuff there!

look good, but by looking at the pics of the coils, look like the rear coil didn't come with the upper mount? do you have to use the factory upper mount?

those teeth on the coilover look a lot easier to rotate than the ****ty sliver that I ve always had to deal with on other brands of coilovers, and those wrenches that barely hook in. Looks like a good product.

Anybody else want to comment on their experience with the Tein Comfort Sport Coilovers, specifically built for the IS-F?

I'm more interested on feedback with regards to some improvement on ride quality and how it affects handling? Not so much on lowering the ride height.

Does the EDFC controller automatically come with the set-up, or is that separate?

Thanks.
