I'm switching to the H&R springs this week, I'll post the results.

I only get the error codes when i do high speed cornering, on test tracks, image of scan attached.. (Ignore the vehicle details, my car wasn't in the database)

Maybe we can get a group buy on the facelift!, I'll more than likely update too.



Thanks, it looks great but I wouldn't recommend lowering in general to be honest.
Yep, lots of noises from install but to be fair I have had similar sounds in my other cars with coils.
My car is now constantly making noises from the rear, pulling it all apart tomorrow, will update you guys.
Spence, let us know how it goes.

Hey guys, does lowering the car with KW HAS coilover kit void my suspension warranty? Thanks.

Well depends on your dealer. MB flagged mine for taking it in with my HandR springs installed. Made a mental note of never going to MB with a mod. They do not take it well at all like BMW does as far as I have heard.

I have the H&R sport springs install and I get a squeak noise going over bumps. I am not sure if it is coming from the springs though because one of my friend on stock suspension gets the exact same noise.

Can you tell me if you are reffering to the number 3 in the picture below?

here's what he found

I went to my dealership, and went in to the mechanics. They directly found a issue that's been reported on squeaking sounds from the front suspension. And a special lubricant oil is used. They didn't have time to do it there, so they borrowed me the oil and I lubricated it my self. It is the "rubber stop" or what ever it's called. That prevents the damper to fully compress. So I lubricated it as they told me. And for 2 days it's been good.

Pretty annoying from a brand new car, and the mechanics said they had a similar problem with the 204. And all this time I've been having headache over this annoying squeaking time. Well well let just hope this lubrication doesn't wear of to quickly.

Sounds like whatever lube the mechanic used has worn/washed off.

So I just got my car back after it was in the shop for a few days, they tried reseating the KWs but decided to flick them and install H&R springs.

I didn't want to have to re grease the kit every so often and it never felt great, always felt parts moving back there.

Took a few shots, I think the height is perfect, it was a tad lower but I am happy with this and it feels stock again, no noise but it is early days!

Looks great! Height looks enough not to get me in trouble in and out of driveways. Would you mind measuring from bottom of fender lips to the ground for us? Or how many inches from the front lip to the ground?

Again, love the stance!

Thanks mate, I imagine it will settle a tad lower, I think the height is pretty perfect, looks a bit more purposeful than the low rider look I had before.

So I just went out and measured from the inside, top edge of the fender lips, front is 26.5 rear 25.7 inches, hope this helps.

After a longer drive tonight I can say I'm really happy, car feels so solid, zero suspension noise, I highly recommend them.

Remember I do have front and rear KMAC kits, I wouldn't recommend lowering without them or some castor/camber solution.

I am getting a squeaky noise in mine as well, which goes away if use a water hose to spray water in the suspension area. I did it just to test that it is a suspension noise. Turns out it is. The noise was gone for 30 mins or so. Came back after the suspension dried again.

By the way I have the H&R sport springs as well not coil overs.

That car looks unfreaking real! Honestly why does it look so damn good? Are you running spacers?

thanks a ton! The rear is a little lower than I would have thought given how it sits. The front measurement is similar to mine now.

I think your setup is smartest of the bunch given your employ of the KMAC kits. Will probably order the springs and bushings today.

Thanks again,

Ha, thanks a lot mate, it's not running spacers, I think it looks a lot better due to the camber it's running, when i picked the car up after it was adjusted It looked a lot more symmetrical, especially the front.

Ahh that's great mate, I hope it works out for you, you'll have no regrets with the KMAC kit, just make sure the shop installing it really knows what they're doing and has the equipment to set it up right.

I noticed straight away the steering felt so good, way more direct, might have just been in my head though!

So I lubed all the bushings and bumper stopper thingy over the weekend. It squeaks even more now!!!! what is going on? Guys will really appreciate some help with this, because I cannot make any sense out of it. I have the H&R sport springs only.

Sorry to hear that, is it coming from the front or back? Mine are still silent, wish they were a bit softer, but silent so far.

It is from the front for sure. A quick test for suspension noise is to spray water in the suspension area and see if the noise goes away. I did that and the noise goes away for 30 mins and then comes back once the suspension dries again. Totally driving me nuts. Have to take it apart again and reinstall I guess. May be that will fix it.

Yes I did, twice actually. I got my full height drop a good two months later because I do not load the car a lot. But the noise was there right from the first day, getting louder as time went by. And it is extremely annoying. Its like a combination of rattling with squeaking, haha. Eats my brain when I do not have the exhaust on to drown it out.

I'm thinking these sounds might be related to install rather then the product .I have the KW Has kit and mine has never made any sounds and I've had the kit it in and out twice
