-Instead of lowering the vehicle 1.5-2.9 inches front and 1.2-2.3 inches rear, they only lower the vehicle 0.8-1.6 front and 0.6-1.4 rear.
-They have rebound adjustment just like the KW Variant 2.
-They cost roughly the same as KW Variant 2.
Thanks for the info..

I also see that eibach pro kit with koni fsd is a nice and comfortable set up..
Iam between fsd's+eibach pro kit and KW street comfort..

Tried raceland's for a while, but took them off.. They were too stiff for me.. especially in our awfull roads here in Greece..
I have H&R sways to reduce body roll and i want a comfort set up..

My Ride: 2005 330 zhp
Cool New suspension

2005 ZHP sedan
Koni /FSD Eibach prokit 2150-4006 Roque RSM,velocity rear trailing arms,Hd front strut mounts,ac schnitzer front strut brace,Hotchkis front and rear sways set med.front ,med.rear 235/35/19 front,265/30/19 rear.
150 miles daily driver no Track drop is alot lower than the specs on website zero gap front ,1finger rear still hasn't settle.
I would recommend this setup to anyone looking for the most comfortable drive for a lowered BMW E46.
paid $ 2000 for all plus install
ride comfort an 8
handling an 7 would like to run sways at stiffest setting,since shocks are so compliant.
Have to get use to the ride, total different feel than Zhp setup,Waiting for suspension to settle ,recheck alignment,readjust sways,tire pressure etc.then post follow up

My Ride: 2006 M3, 6mt TiAg/Bk
year and body style: 2006 M3 coupe
setup being rated: AST 4200
possible adjustments: Ride Height, Adjustable Rebound Damping, Adjustable Compression Damping
additional components: Vorshlag Camber Plates v2, AST Solid Rear Topmounts, Vorshlag/AST cable adjustors (rear)
wheels: OEM 18's with Dunlop Direzza Z1 Star Specs 245/275 F/R

compression damping: 2/12 clicks.
Rebound: 6/12 clicks front 5/12 Rear

alignment: pending, currently sitting at minimum camber on the Vorshlag plates up front, so about -2 deg, ride height is at 13.5" front, 13" rear

preferred ride style: Sporty and firm, but not bone-jarring
would you recommend this setup: Yes. Absolutely, as long as you're planning to go to the track semi-frequently.... overkill for pure street driving

price paid, including installation: $4100 for everything including new OEM RTABs and Vorshlag limiters -- Installation was DIY -- $50 of shop time

ride comfort: 8/10. Potholes suck, but generally better than OEM -- firmer, but not as harsh. Probably about as good as you're going to get with these spring rates (550 lbs/in front / 650 lbs/in rear)

handling: 10/10. Going to Spa Francorchamps next Saturday, so expect more info then. Absolutely no body roll, and steering response is positive and immediate.

Instead of making a new thread about this, I thought I would start off in here first.

Does anyone have either the Turner Motorsport rear camber adjusters or the Ground-Control rear adjusters? They're the exact same price, but have a slightly different construction method. I like the idea of the GC lifetime warranty and it looks like they're made very very well, but the Turner setup looks a little more beefy.

anyone have any thoughts or concerns? -I'm looking to run about 2.5 degrees of rear camber in the rear with 650# rear springs, koni yellows all around, m3 vert sway bars, 450# springs in the front, Meyle HD tie rods, control arms, CABs and tie rods, and Ground control front camber plates in my 2001 330i

Student, depending on what you plan to do with this setup, I'd make a couple recommendations:
1) You may find 450lbs front to be too soft for track/autocross driving, depending on the tires you use, the temps, and the surface you're driving on. I'd recommend 550-650 if you want to keep out of the bumpstops up front. (you do) 650 rear is probably pretty good.
2) Avoid the Meyle Control arms, CABs, and tie rods, they just won't last as long as the Lemfoerder. I know this from having used both.
3) Depending on ride height, you should be able to get that kind of rear camber without the camber arms, but they certainly won't hurt.
4) It has been my experience that Ground Control, in general, has no priority on street civility. Depending on how you plan to use the car, you may want to read up on the kinds of bushings they use in their kit, if any. (I'm not familiar with any of the rear camber arm kits)

murph, I uh... already installed everything except for the camber stuff about 3000 miles ago . I'm already feeling like the front springs should be a bit more stiff, but I want to finish up getting the rear sway installed and a few other small things first.

The reason why I'm looking for camber stuff isn't as performance minded as it could be. I have a set of wheels that I'm trying to use that require a bit of work to make fit. They're BBS CHs that have m3 fitment. The fronts are dead even with the fender and so I want to bring that in just a small amount, and the rears have a decent amount of poke to them that I want to reign in a bit to tie in with some fender pulling.

I'm not totally sure I'll be able to make the wheels fit, but I'm not overly concerned about it. If they fit: awesome. If not: I'll have gotten more of the components needed to turn my 330 from a boring to fun in the corners and can sell the wheels to get different ones.

also: IF i get the chance to autocross the car this summer (between working two jobs and taking summer classes) I will, of course, be using a square tire on my style 68s, and not a stretched tire on the CHs.


Edit: I don't mind the rough ride that the ground controls may create. I don't have any old ladies riding around with me to be too worried about

ahh ok, well your alignment shop should be able to get -2.5 degrees in the rear without camber arms. (I can get that, even at my highest ride height of ~13.25") In the front, if you haven't purchased the camber plates yet, definitely go Vorshlag.

If you can tell us what offset & width the wheels are, I can probably tell you whether they'll fit. (running 18x9 & 265's daily)

The wheels are BBS CHs 19x8.5, 19x10 et 20 all around. The fronts are dead even with the fender with 0 camber and the rears have almost exactly an inch of 'poke'

I picked up the wheels knowing they probably wouldn't fit, but wanted to try. I've done the math though, and if I do 2.5 degrees of camber it'll bring in the top lip by ~0.46 inches, and I don't think I'd be able to pull the fenders more than a quarter inch, so that would mean that I would still have about ~0.3 inches of poke.

At first I thought I was okay with that, but I've been thinking about doing driving schools this summer and I'm not really in love with the idea of running stretched tires at an event like that, so I'd end up having to use a different set of wheels ever time I did an event... which would equate to two alignments every time I wanted to do an event (one before, one after)

I'm kind of thinking about just getting the camber stuff and selling the CHs and running a wheel that I can do a square tire on and use for street and events.

p.s. are you on eurowerks.org?

Hard to believe you guys say that your ride comfort is better than stock. Im no expert but when you lower your vehicle and jump to low profile tires, ride comfort is significantly lowered. Im running KW V2 Coilovers and 235/40/18 and the ride is considerably rough. I rode in my cousins stock 328 and it is night and day in comfort. I would rate my comfort 6.5 or 7 and definetly 10 for handling. It really comes down to personal preference, but they do look sweet lowered with wheels!

I have instaled Eibach Pro Kit springs with stock brand new sachs shocks (black) and comfort is very good, looks nice (i have 17 OZ Ultraleggera's) and handling is also ok..

I will post some pics when take some new ones..

My Ride: 2001 330i M-Sport TT
year and body style: 2001 320d
setup being rated: KW V3
adjustments: Ride Height & bump/rebound damping
additional aftermarket components: Powerflex Poly Bush Kit, Front and Rear Strut Braces
additional info: car has 75k miles on it. About 3k with this setup
preferred ride style: Quite firm, very little body roll, and more of a track biased setup if I am quite honest, however the wife never complained even after warning her the car would be "firm" after the upgrade, very composed and connected feel behind the wheel, Bump and Rebound adjustments did not appear to make as large a difference as one would expect when taken from one extreme to another, most impressive is the fact that the car does not crash around on the road on the less than impressive road surfaces we endure in the UK,admirable damping qualities indeed given the track performance.
would you recommend this setup? Yes, for track biased cars
price paid, including installation (if applicable): Circa 1500 installed.
ride comfort:7
handling: 8

My new PSS setup

Ok, really I just have a question but I'll post the details of my setup also:

Question 1: I had an alignment done and the shop said I needed Ground Control camber plates. Does that mean that the insides of my tires will wear now?

Question 2: How can I find out the optimal ride height for this setup? Should I just use the sport suspension specs from the Bentley manual?

Ok, TIA for the answers. Here's my setup:

2003 E46 Sedan
Bilstein B14 PSS coilovers (sport shocks)
Both front and rear adjustable with manual wrench (threaded lock rings)
Stock (I know I need new rims!) 16" rims
93k miles
Drop approx - 1 3/4" front, 1/4" rear

I prefer a smooth ride so this setup is a little harsh for me but I LOVE the way it handles. It feels like it's better than when I bought it.

I would definitely recommend it.

Paid $850 + shipping + tax. I installed it myself.

Ride comfort -8
Handling - 10 (although I've never driven a Lotus so I can't really compare it to anything better).


Overall: installation was a breeze. I used all the DIY's around the net. However, I would have prefered actual instructions from Bilstein. Also, no one ever mentions to set the ride height BEFORE you install it. Because once it's on it's not that easy to adjust. I think I have to take the tension off the springs in order to turn the locking rings. But the car is a guided missile now. I'm in love again!

Wheels and ground clearance?

would you recommend this setup? Yes
price paid, including installation (if applicable): Sorry not sharing got the suspension on closeout from TireRack for $406, but I had it installed with a few other items so total install cost more than the actual Cupkit cost.
ride comfort: If stock non sport is 10 -- 9 -- slightly harder than my stock non sport on some bumps, on others it rides better
handling: lets say my stock non sport was a 4 this is a -- 7 -- controlled body roll well, feels more confident in turns, but I am still planning on doing aftermarket sways in the near future.

This is a fantastic setup I highly recommend to anyone. My car was on stock non-sport suspension with 65K miles. The cupkit feels only slightly harder on certain bumps in my daily route, yet on other bumps it rides better than stock. As you can see in the pics below the drop is good. H&R lists the drop at 1.3" front and 1.2" rear. My actual measured drop is near 1.75" front 1" rear (with 15mm spring pads vs stock 5mm). The wheel gap all around is right about 1 finger, so visually it is an even drop which I wanted. My front lip spoiler occasionally bottomed out on the stock suspension so with the added drop I am having to really be careful on bump and driveways.

Here is a pic of the kit...



Pics of car...




Beautiful car!

I have an 01 325iT w/ Bav. Auto. springs and Bilsteins. They said 1-1.5 drop; I don't think so. With stock wheels and tires (205-55-16) I have about 3.5-3.75 in. ground clearance in front. Speed bumps are treacherous! I'm guessing the actual drop in front was more like 2+ in. This is too much drop for springs this soft.

What size wheels and tires do you have? What's your ground clearance?

Ok, I suppose I owe this great thread my review:

year and body style of car - 2001 325iT (wagon)

the suspension setup you are reviewing - Bavarian Autosport "performance springs", Bilstein Sport shocks.

if it is an adjustable setup, mention how it was adjusted and what range of adjustment is possible - non-adjustable

any additional components on your car that may affect ride quality (aftermarket rims/camber adjustments/strut bars/sway bars/etc.) - Hotchkis hollow front sway bar, stock 16 in.wheels with 205-55 Falken Ziex, Ebay Schnitzer knockoff strut brace.

any additional info about the setup (miles driven/amount of drop/etc.) - front dropped at least 2 in, rear about 1.75 in.

the ride style you prefer - moderately stiffer than factory, compliant enough for rough roads

would you recommend this setup? - No, because the front drop is too much in relation to the softness of the springs. Otherwise the ride is very nice and controlled, lean and turn-in are acceptable with the Hotchkis bar.

price paid, including installation (if applicable) - $724.27 from BA, $412 install.


based on a 1-10 rating scale, describe the following categories:

Ride Comfort - 10

Handling - if 100k mi. factory springs and shocks were a 4, this is 7.


and finally:

a paragraph about your experience with this specific setup - Main complaint is too much front drop and resultant scraping over speed bumps, etc. BA advertised only 1-1.5 in drop which would have been fine. Next time I will go for stiffer spring rates and same or less drop. Handling was loose with equal tire pressures and stock sways; stiffer front bar made it neutral and turn-in is crisper. Bar is set on middle stiffness adjustment.

I haven't personally ridden on them, but I've heard that while they're good shocks, they can be rather firm. With the kind of roads you've got up there, you might want a softer shock. I think Koni FSDs would be the way to go. I only wish they came in M-fitment.

About the upper strut bearings - IF your shock towers are mushrooming, then you should get new strut bearings.

Well, I have the Bilstein Sports with a spring set that is supposed to "ride close to stock". So I suppose the HD set with stock springs would be similar to mine except for a higher center of gravity (a bit more roll).

I have always liked Bilsteins on every car I've had them on. They dampen small motions almost invisibly and handle larger motions with a beautiful smoothness. I've never found them too stiff for any road use - pick your spring rate and trust the Bilsteins to do a great job.

Another related tidbit I'll pass on from my indie mechanic - he has seen several E46 3 series front strut towers actually tear from a good smack to the front wheels. Apparently they are a weak link and that's a difficult damage to repair. A strut tower brace will protect you from that and improve ride and control.
