10k/8k is too soft for an IS-F, they are suppose to be for an ISX50. The IS-F weighs more, so if you get the 10k/8k your screwed haha.

The reason that guy says the 14k/10k is stiff is because he has a regular IS. 14k/10k is the recommended for the IS-F, recommended for 2IS is 10k/8k.

I would have got the BC if I had all this info before I made my purchase on the KW V3's. The 1k savings on my pocket would have been nice.

The figs settings? Are the clicks from hard or soft. Meaning do you go to full hard then 20 clucks torward soft? It has been a while since i touched the dampening settings.

Hi Mercury..the direction is from full hard. If you are on 14/10 spring rates set the damper to 9 clicks front and 14 clicks rear from full hard. Those settings provide a nice smooth ride for daily driving. I have mine set to 9 front and 5 rear and it still rides pretty smooth as well. Adjust from there to your liking which is what I did. Also, I did not use the extenders that came with the coils. You can easily pull the lining in the trunk and gain access to the *****. It is not that hard rather than making holes in the lining. I do not track nor race so once I have it the way I like I left it as is.

I'm late to the party! I just got the 16K/12K springs done and with it at 8 and 10 clicks, it felt a little more controlled but stiffer than stock. Right now I got it at 20 and 15 clicks and man, it feels like an ES350! LOL (not quite - but you get the idea). It doesn't jounce/bounce. I'm afraid that if I go 25, 20 clicks from hard, it might start to bounce due to the 16/12K springs.

Now I can DD it nice and smooth (99% of the time) and go hard at the track (less than 1% of the time).

I gotta admit, it really does make the car feel more luxurious!

really? i got 16/12k and slammed the car and it doesnt feel super stiff even at max settings

ToothDoc

I think the 16 and 12 K springs actually give me less bodyroll - I'm guessing that it's a little stiffer than stock. It's hard to compare the dampening from stock though. Obviously 20/15 is MUCH softer than stock but I think 8/10 is comparable to stock 08 suspension.

I keep mine at 10 clicks down from max all the time. Seems to be a perfect balance for the street and track.

ToothDoc

16 and 12 k bc coilovers. 10 clicks in the rear and 15 in the front. Much smoother than stock and yet the car somehow feels a lot lighter in the corners.

Just to confirm - are we talking the BC Racing BR Series? Also, can you keep stock springs or are the Swifts necessary?
