KW HAS Kit Opinion

f80_brian · 11-12-2020, 12:25 PM

Who here is running the KW HAS Kit? Want to hear some opinions on ride comfort and etc. before hoping on it.

Thanks in advance!

Slightly stiffer than stock non ZCP adaptives in comfort
I think they're actually better than stock in sport
Mostly for looks over performance

I’m quite pleased with them. I think coupled with CS coding it is an excellent upgrade that combines the flexibility of adjustment, improved handling and use of the adjustable ride comfort settings. Best of both worlds without “needing” to spend another 4-5k. I find it peculiar most think lowering a car .5-.75” suddenly changes the entire dampening characteristics of a car with several inches suspension travel and adjustable dampening characteristics with coding. Are the more expensive options better? Maybe, but I don’t see anyone who claims as such out driving the car to where it makes a difference.

My car came with them so idk how the stock ride quality compares to them but overall I think the ride quality is pretty good. It rides a lot better than my old cars stock suspension so I'm perfectly happy. It corners pretty well and the ride quality isn't jarring or anything. My only complaint is it can be a little bouncy going over bumps in the road at speed and if you're trying to do a pull on a rough road the car can feel unsettled

So I switched from 19" to 20" competition wheels and added 10mm spacers all around and KW HAS kit. I am not sure what to blame it on but the car seems floatier. I think it became more prominent with the KW kit.

Idk if that helps in any way.

does your car have EDC, if so what do you have your shocks coded to?
I don't know what the KW HAS advertises the spring rates to be +/- over OEM.

I could be wrong but I believe this to be a continued point of contention, KW not releasing the specs.

It does and I am not sure what it is coded to.

part of this depends on how much you dropped your car and what setting/code you have it on. The tough part is we don't know what the spring rates of the KW setup is. I have the dinan setup on mine and on the ZHP or CS coding it's not floaty at all even in comfort mode.

BlackF82 · 11-13-2020, 12:34 PM

Oh ok, so by coded you mean comfort/sport/sport+? If so, it doesn't matter what it is in, its floaty at high speeds. Its great at fast 90degree turns though, very planted.

there is software that codes the rebound and compression of the edc. the coding for the cs, comp, and non comp are all different

coding is fine by flashing the module. not by pressing the suspension button

Did you get an alignment after by any chance?

Yes and all 4 tires balanced.

I did actually have coding done recently while I did other coding, M4 CS suspension.

Sorry OP, I hope I am not thread jacking.

Adcampo · 11-13-2020, 06:24 PM

I'm debating between the KW HAS, M Performance and EMD springs.

I've got a comp pak with eds.

I think the EMD's might be too low and compromise ride quality.

I read the CS tune with EDC is a sweet set up.

You're all good! Love open discussions

I was thinking of switching to the KW HAS kit since I've been waiting for my emd springs for 3 months now and they finally shipped out yesterday right when I was about to cancel my order. I just like to have the ability to adjust the height to my liking.

For the price might be worth trying the emd's. I've read nothing but good things. My personal opinion is they might sit a bit to low for a man in his 50's.

I'm looking for something to close that front wheel well gap some.

m3elmo · 11-14-2020, 08:28 AM

EMD definitely lowers the front compared to the rear. note that many m cars have a larger front gap because that's the designed ride height. you can tell when looking at the rockers

below are the emd specs. ride quality should be similar to stock. 1.3 in the front isn't all that low....

Front Lowering: 1.3"

Rear Lowering: 0.3"

Stock Front Rate: 186 lb./in.

eMMOTION Front Rate: 194 lb./in.

Stock Rear Rate: 608 lb./in.

eMMOTION Rear Rate: 645 lb./in.
