Hi Harold, this looks awesome...

1) Please provide a price the DA ones.

2) Do you need the camber plates with these if you get the M3 front end bits ? (to get more bite in the front end). In order to dial out the understeer.

The idea is to not get sways, but get the front end bits to get .75 of neg camber and then dial out the understeer with the DA shocks. This keeps the cost down - especially on the rear bar install.

3) If I wanted to maintain ZSP ride height, and ZSP or better ride quality - can we do that ? or do we need helper springs (and how much are they?) - I could handle 1/2" drop max probably....

Thanks

Approx. $1000 more

You will need camber plates to get more than -1.5 of camber. With 400F 800R the car should be pretty balanced, even without sways or we can tone it down a bit if you are doing mostly street driving.

3) If I wanted to maintain ZSP ride height, and ZSP or better ride quality - can we do that ? or do we need helper springs (and how much are they?) - I could handle 1/2" drop max probably....

You can get within 1/2" of ride height with our SA kit. The rear may sit a bit low, but with rear helper springs you will be at stock or higher for sure.

Great... a few more questions please.
Camber plates -
1) Do I need the camber plates with these if I get the M3 front end bits ? (to get more bite in the front end and get rid of the understeer.

2) how much are yours ? Is there a deal on the package?

3) I have read in this forum that camber plates make noise (if they are adjustable) - I believe the ones you sell are adjustable - please comment.

4) What are your camber plates adjustable too?

5) Tire wear - if I am only street driving and not tracking but want crisp turn in and NO understeer - what setting on camber should I use ?
- IE: Do I need camber plates if I go with the M3 front control bits (that adds negative .75 camber I believe)?

Springs and Helper springs
6) Can I go the full ZSP ride height with helper springs ? What I would want to do is maybe dial it all the way up for the winter, and dial it down 1/2" or more in the summer.
- Is this possible Harold?
- What is the cost on the helper springs ?
- Is there ANY issue with noise or any CONs to using helper springs
- How easy is it to dial it up or down?
- Is an alignment required each time on height adjustment of 1/2"?

7) I want the car to have balanced handling (no understeer), less roll, handle mid corner bumps better, and have a better ride on the highway. What spring rates would you recommend?
- I don't think I will track it, but I may do an autocross, but really it is for very spirited driving.

8) How easy is it to adjust these? Will they be adjustable from the top of the shock under the hood in the front? What about the back? Do I have to make holes in my truck liner? (can you post a pic of the adjusters please).

You are awesome - thanks.

I am sure someone just emailed or PM with the same questions you have. I sent you a PM instead.

Harold - I have the exact same questions. Could you post the answers or send me a PM? Many thanks! PS - I have an 335i E92 ZSP - stock at the moment....

+1 for the PM

A bit O/T, but I had Harold put in the KW/V2 and M3 suspension a few weeks ago. All I can say, go-kart like handling. It's an awesome system. I actually now have to keep the car from oversteering. 90 degree right hand turns at 50 miles/hr doesn't even make the tires squeal. Don't mean to threadjack, just chiming in.

[LOLrance]

Im loving my Koni DA's! Im sure these are a great alternative to the standard choice of PSS9/10, KW v1/v2's.

Harold, how would these compare with the KW/V2s for performance and price?

NJ65, did you put in the sways as well, or just the M3 bits?

Thanks for this.

[NJ65]

Yea, front and rear sways too.

[mwahlert]

what are the softest spring rates available?

[bogeygolf]

Question for those people who have been doing the research-- How might these compare to the kit produced by Ground Control? Those also include the M3 control arms, and similarly use the Koni Shocks. Any additional comments comparing these two, and or KW V2 are very very much appreciated.

200s for the front and 500 rear.

There is no comparison. The V2 uses stock profile proggressive rate springs, which are very heavy and the rates are too soft for any performance driving. Our SA system uses high quality Swift springs and thrust bearings.

In addition, you can not pick and choose your own springs rates with KW.

For the V2 to be on an even playing ground, you will need to spend $672(Swift springs and thrust bearings) plus some machine work.

[gn02931341]

what is the different between DA and SA?

[cpt97m3]

...or did you mean the diff in price?

Also, the Koni DA's have more race oriented internal specs so are better for track use. They still work good on the street, but might be a tad overkill for pure street use. The DA's are great if you do some autox/track events.

[forza1976]

Man, those look so nice. I'd jump on those if I didn't already have KW's.

[Driv3r]

im looking for really just tightening my car back up it currently has 50k and ZSP. what would DA's include, somebody said something about M3 control arms? i have a squirmy/unsettled rear end.. im not sure what I should replace..
