Does anybody have any comments/comparisons between the kw v3 and bc raxing coilovers? Asking for differences in functionality.

hahaha im the one who told kashan to get kwv3...lol...guess he never looked back. I spoke with Renatik and I don't think he can go wrong with either one. good luck on your decision. if ur planning to get the kw v3 get it with the top hats. it will save you some time.

We never got an update that they come with upper hats now and the install instructions are the same revision from 2012. We sell them at MAP which is the lowest price to maintain a warranty.

Dont get me wrong, I like the BC in stiffer rates and they are a large improvement over stock from what i have seen, but I have a serious gut feeling the KW rides better at lower speeds. I think when you make the BC fairly soft the ride gets bouncy, which I dislike. When they are stiff I am impressed with their stability. I have already noticed the BC short travel distance with the roads in upstate NY and VT...potholes are rough on these coils. I will switch to Ohlins when a proper ISF version is, if ever released.

I would have to agree with you darbs, however I just finished installed my BC R with the swift option (16/12) as per figs suggestions. The new BC's ride very very close, if not the same as the KW's. Plus I would never realistically play with all of the settings the KW's have.

That's why I got rid of BC's and just went with springs. They were bouncy in the softer settings and I felt the rears were dipping too much. I too am getting bored with my F. As much as I love it, I am really considering sporty replacements.

The dual flow valve will always provide greater comfort than a single stage however the spring should be more instrumental in travel limits with the KW that they are allowing. KW v3 for this application is a street coilover and comfortable.

In other news we are getting closer on the Ohlins front. Keep in mind that Ohlins is never going to release a IS-F specific RT kit because they are subject to what they get out of Japan. So we are going to have to revalve them and respring them plus add rear upper hats since they currently use the stock parts in the rear. But that will still be less expensive than the Penske setup we offer.

Hello everyone,

I just went thru a few KW coilovers threads. Some noted that coilovers need to be rebuilt after a while.
What is an average lifespan of a coilover setup, if used on a daily driver, no track use, just lots of "spirited"
driving?

Also what is the process of rebuilding those?

What might be the average cost of rebuilding these?

KWs are quite durable. If you're the original and have the receipt, they offer limited lifetime warranty. They will only service your shocks for free if you adhere to the height that KW recommends. If you slam the car and ruin the coils, you'll have to pay for it. It costs $180 per shock and you'll have to cover the shipping to KW. They cover the shipping cost after the service.

If they take the coils back under warranty, you cover the shipping to them and they pay for shipping back to you. The turn around is usually 2 weeks.

As long as you stick to KW specifications, the coils will last a long time. I've seen KW V3 with over 50k miles and numerous track days and they still function as they should with no issues.

Hope this helps.

Thank you so much for the info. All the threads indicate that KWs are a must for my 2010F

I don't remember the exact numbers but I set it somewhere in the middle of KW recommended highest and lowest height.

I've owned the following suspensions:

Bilsteins PSS9
Tien Super Street
KW Variant 3
Eibach Springs
H&R springs
And now BC coilovers
All on different cars. All lowered. All drive. Aggressive on. In short Let me tell you get the BC because they ride great!!!

Thanks, T! Looks great. I want to go a little bit lower than that on 20s so that's good frame of reference.
