Competitors to KW V3 and who ran Greddy X KW

SPDKING

As the title suggests, what are competitors to the KW V3 coilovers? I'm getting rid of my brand new Adjustable Koni Yellow dampers (you can PM me if you want them) and I'm researching coilovers for heavy street and canyon use and light track use and everyone points to the KW V3's.

I came across the BC ‘ER’ series coilovers which are supposedly a competitor to the KW V3's but I think I want to stay away from BC. Also the Bilstein Bilstein B16 (my favorite because they look pretty), HKS Hipermax III, RS-R Sports*i but I've also came across some Greddy X KW coilovers that I've noticed not too many people have or talk about and might be better for my application since my car will be street driven the majority of the time.

What are other competitors to the KW V3?

Who has bought and used the Greddy X KW on the street and track or the Bilstein B16? I'm really interested in these two and it looks like they aren't popular in the community for some reason.

Here is the Greddy KW X I was looking at for mostly street use and occasional track use https://www.z1motorsports.com/suspen...s-p-10461.html

Here is the Bilstein B16 https://www.z1motorsports.com/suspen...pe-p-9166.html

Those Greddy X KW coils sound great but when i was looking for coils myself i didnt read anything on them, so i kinda doubt there is much on them.

The KW V3's on the other hand are extremely well reviewed on here for the z and even on the net for other cars.

Not a fan of B.C Coils, but i do hear great things from Bilstein Bilstein B16 coils although i hear they are also on the more expensive side. Should you decide KW V3's let me know i have a pair that will be going up for sale in 1-2 weeks once they are off the car.

Yeah, 164 views and no one even know a buddy of their's that have tried them out? I like the V3's but I'm not building a track monster so I don't want to waste my money if I'm not going to using it's full potential.

I would look at tein coilovers z1 has them on there race car. my friend has them on his 2010 z. He also has the auto adjusters, they ride super soft on the street, I forgot the rates maybe 14/12 not positive. He use the for autocross and track days. I personally have driven many cars with coils 5 diff types in diff cars.he paid about 2300.00 for them . He likes them better then his online in his race Miata. Worth a look hope it helps for what it is worth. Jv sorry for auto correct I’m tired. My personal race car was 06 sti I had kw v3 500 /500 they were good but not a lot of droop travel but that is a Subaru thing I believe. I now have a 18 nismo but I’m in a stock class. So when I change classes I will but these for mine

Maybe even Tien Coilovers with EDFC ACTIVE might be a good option also!

I would give fortune a look as well. I'm on 500 and am really happy with them. All the choices you have pretty solid. I don't think you would go on to regret buying a set from either brand.

My research indicates Fortune 500 is an excellent option for the track. Plus you can get them revalved in the US.

Seems that a couple people like the Fortunes which are pretty new. I've read about them on the track and they are well liked. I didn't see anyone saying much about street use though.

Aragosta Type-S 14k/10k
Comfy as hell on the street, comparable to stock, even with full SPL parts arms

valving matters

A big variable is the spring rates you choose... if you choose stiff ones for track use they aren't going to be very nice on the street. Softer ones for the street may not be appropriate for your track use. You can't have it both ways unless you want to swap out parts.

I know, I figure the sweet spot for people looking to tip toe on both sides might be 7-10k up front and the same in the rear with preferably progressive springs. I've only ridden in two different cars with coilovers, one with the V3 and one with the BC ER series. V3 I liked but the BC was shaking like a Chihuahua over bumps. The custom spring rates were 14k up front and 12k in the rear on the BC car I drove and it was horrible and knew immediately I didn't want to go that high but I'm sure it was awesome on the track. I do like that Fortune auto dyno tests each coilover similar to KW though. I'm starting to like what I see.

Don't forget its also how the compression/rebound etc.. was dialed in.

You’re getting too much advice and some of it is bs regroup, take a breath. Just because it’s in a article still may not be true, look at at the articles that say 370 is old. There just full of crap, you’re best bet is to get a ride in a car with the ones you want and see for you’re self. One person opinion on what is a stiff ride will depend on each person you can get coilovers that are good for track and ride them on the street. Probably not there entry level one will ride like crap. Call z1 and have a specific conversation about there tein coils on there race car. If you want my friends advice on his and his set up I can do that . It also depends on you’re skills if you’re a novice cheap one or expensive one may not help . You need a certain amount of driving skills to get the benefit of most mods.

Agreed. Manage your options, get personal feedback, and look for value. Honestly, what is your budget?

I've had Swifts for the past three years and loved them compared to the stock springs. I drove a friend's Z that had BC with Swift upgrades and determined that was the next step. For the money, they made sense. Having ridden on them for a month or so, I can tell the most subtle differences. It's definitely not the same over big/rough bumps, but in the corners, it's a huge difference. As I become more skilled, I'll probably buy a different set of coilovers, but for now, this is great. The progression is the fun part. Honestly, I think if you buy coilovers that exceed your ability, you'll miss a lot of the fun.
