Everything You Know About The ZHP

[Marcus-SanDiego]

Xenon lights were an option.

Black cube trim was standard. Silver cube trim was the option.

The ZHP coupe, in 2004, had a trunklid spoiler delete option (code 326).

Some ZHPs, in early 2004, did not come with trunklid spoilers (even though customers ordered the car with the spoiler) -- because of a parts shortage. Customers who complained eventually got them installed at the dealer at no cost (covered under warranty).

2005 model year, moonroof became standard

[danewilson77]

ZHP - Performance Package
The performance package was available on 2003-2005 330 sedans (330i) and 2004-2006 330 coupes and convertibles (330Ci/330Cic). In 2003, it was only available with the 6-speed manual transmission and WITHOUT the premium package. In 2004, all performance package cars were also available with the automatic (steptronic) transmission as well as the premium package.

Obviously, the Performance Package is a level above the Sport Package, so they're not available together.

Per the BMW press release, this package included the following changes. However, many of these claims have been found to be misleading:

Engine mods (new camshafts, electronics, & lighter flywheel) for 10HP & 8 ft/lb of torque increase & 6800 max RPM (from 6500).
6 speed short throw shifter (for manual transmission equipped cars)
3.07:1 Final drive ratio w/ manual trans instead of the standard 2.91:1. Convertibles retained the already installed 3.07 ratio.
Max Speed Limiter set to 155 mph (instead of 128)
New M suspension, more "sporty" than standard sport package:
Firmer springs (front +6%, rear +8%)
There are no "ZHP" specific springs. The same springs are used for comparably equipped 330's for both the ZSP and the ZHP. In both cases, the spring rate for the post 4/01 build ZSP and ZHP is believed to be slightly less than that of the pre-4/01 ZSP
Firmer shocks (Jounce: front +50%, rear +20%), (Rebound: front +35%, rear -8%)
ZHP does use different dampers than the ZSP. There is a shortage of shock dyno data, but based on the SACHS damping parameter values it is believe the jounce damping is the same but rebound damping is stiffer on the ZHP. Pre-4/01 sport package cars had similar damping values to the ZHP but used the higher grade SACHS "Advantage" dampers rather than the "Super Touring" model
Larger diameter anti-roll bars: 23.5 mm front (v. 23.0), 18.5 mm rear (v. 18.0)
Sway bar diameters are 23.5 mm and 18.0 mm for all post 4/01 build 330's. There is no 18.5 mm rear sway bar offered by BMW for the E46.
More rigid forward bushings
Front Control arm bushings are the same ZHP/ZSP
ZHP control arms are different and use a stiffer ball joint
Lower ride height by 15 mm (.6 inches) utilizing shorter auxiliary springs
Since both the ZSP and ZHP use the same springs, they have the same ride height. Both are 15mm lower than a non-sport E46
-.5 degrees of camber (for a total of -1.1 degrees)
Alignment settings are the same ZSP and ZHP
BMW M exterior trim elements (front & rear fascia, side sills, & trunk lid spoiler)
Special exterior trim: Anthracite (charcoal) headlight & foglight surrounds, High-Gloss
Shadowline (black gloss) trim
Large diameter stainless steel dual exhaust outlets
Extra thick Alcantara steering wheel (later switched to perforated leather)
ZSP Sport Seats
Alcantara & cloth upholstry to replace leatherette and standard trim (leather still optional)
Choice of "Black Cube" or "Silver Cube" interior trim
Anthracite headliner
Red needles on the instrument cluster
Unique 18" Wheels (style 135M), 18x8.0" front, 18x8.5" rear
Wider Tires: 225/40ZR-18 in front and 255/35ZR-18 in the rear.
Quicker steering rack ratio. 13.7:1 versus 15.4:1
All post 4/01 330's use the same part number steering rack. The ratio of this rack has not been confirmed, but it is believed to be different from that used on the 325's

That is all. Thank you.

Sometime in mid-2005, the steering wheel changed to a leather perforated one, replacing the alcantara wheel.

I am not attempting to get into the detail of purported ZHP rack's existence or other in this thread, just reporting on the install

After doing all my research, I believe I was able to isolate the mysterious ZHP rack part number - and then able to obtain a rack.

The quicker ratio steering over the 325 stock rack is immediately noticeable.
This was a simple and relatively cheap mod.:thumbsup:

http://forum.e46fanatics.com/showthread.php?t=809438&highlight=zhp+steering+rack


I came across an interesting factoid while doing this research - all photos of racks on actual ZHPs, depict an identical (differing manufacture dates) yellow tag, listing ZF part number. Again, perhaps coincidental, but I have come across 5 actual photos (enclosed) and they all have the same tag. Further, the production dates of these 5 racks range from 10/03 to 05/05, so appears there may have been some consistency using this specific rack across the years. I have also seen standard 330i tags and they have different ZF numbers.

Sometime in mid-2005, the steering wheel changed to a leather perforated one, replacing the alcantara wheel.

Was this after the end of sedan production? I've never seen a zhp sedan with a perforated wheel.

Not sure about the sedan steering wheel...i have the leather on my 2005 coupe (luckily)

I really like my Alcantara steering wheel. A little TLC and I'm good to go; plus, its a perfect application for driving gloves. I don't have a single car-crazy friend whose ride has such a feature. Leather wheel - nein danke. Alcantara is one of the many charactaristics that makes my Z a stand-out...

14.5:1 Ratio (Standard M3 15.4:1)

[pyreguy]

The way the steering felt was the third thing that really impressed me about my ZHP. The first was the exhaust note as the PO pulled into the parking lot to meet me, the second was how the fuzzy seat hugged me when I sat in it. I still love all of those, but I am really glad the steering is the way it is cause that was a source of contention for me and my previous car.

[az3579]

Correct. Last month of production for the sedans was 1/05 in the US and 2/05 in Europe.

[nk_zhp]

It should be noted that the suspension in reality was no different from SP. Aside from bigger/stronger control arms.

[rikdee]

Just an anecdotal comment on the steering [rack]: My friend, to whom I sold my E36M3, when taking my ZHP for a spin, was surprised by the (as he put it) 'go-cart like' steering as compared to the E36. Irrespective, our cars, whether or not having the same steering rack as other performance E46 models, do exhibit really sharp steering response.

[pyreguy]

The clear lenses didn't come on sedans

[MasterC17]

It should be noted that the suspension in reality was no different from SP. Aside from bigger/stronger control arms.

The ZHP also had different dampers. The control arms I think have replaceable ball joints.

[danewilson77]

No replaceable ball joints. Just a lil heavier.

I think dampers is referring to shocks, now termed struts. :shifty

Shocks and Struts are both used to identify front vs back. Struts are upfront (inside a strut housing), shocks are in the back. Dampers are, as far as I know, referred to either of them.

You were right in the middle of the parts shortage. It's obviously been a long time. However, here's how I would play it. Say that you just found out today that you were supposed to have one of these on your car. In fact, pull up the option sheet for your car. See if option code 326 is on there (spoiler delete). If it is not, see if your local dealer will do a goodwill adjustment for you. See if they'll give you one and install it for you (it's just 3M double-sided tape that holds the spoiler on). You'll need to get it painted too -- perhaps you'll pay for that out of your pocket (as a sign of compromise).

Seriously, if you have a good relationship with your dealer, it's worth a shot.

[danewilson77]

Or....buy a $40.00 lip spoiler....get it painted and put it on yourself.

[Marcus-SanDiego]

The OEM spoiler is only $40?

Also, I would go the free route first, though. Then, if all else fails, go the Dane route.

[CERF04ZHP]

RealOem prices are all over the place, both below and above BMW retail prices. I've stopped looking at their prices now because they are so out dated. Many items are way cheaper, then on the other hand a $5 bolt on Real Oem is $19 wholesale so it is almost pointless to note their prices. I use it just for part numbers and diagrams.

[danewilson77]

Its still ball park imho. The realoem numbers typically seem to be more or close in my experience. Haven't seen it low too many times.

[lilcdkey]

I had one quick question guys, is the leather from ZHP seats any different from normal 330 seats? I have a 05 ZHP with 46k miles and maybe just because its newer and less used, but It feels so much better than my friends 01 330ci and even different from my brother's E92. I've also heard someone say that they are Nappa leather, but isn't that only used on M3's? I searched already but nothing came up.

[Marcus-SanDiego]

BMW didn't give us anything special v. the rest of the 330 world. Most of us, I suspect, have Montana leather. Not sure if Dakota was introduced toward the end of the E46 production run.

M cars got Nappa.

My 2005 ZHP has Montana leather.

[danewilson77]

Mmmm....I think the leather is different.

[Marcus-SanDiego]

Dane, if you get confirmation of that, let us know. It was my understanding that we all had the same leather (minus the M3).

also, mid-2005 they switched to perforated leather

Mine has leather steering wheel (no zhp) Maybe they ordered leather..

[johnrando]

I'm sure a mod will clean up these extraneous comments, but for the record, mine has a perforated leather steering wheel.

[Washburn]

factory perf-leather wheel started in mid-2005, and not 2006.
Mine is a 2005 coupe, and has factory perf-leather wheel.

[Marcus-SanDiego]

From the FAQ:

Question: So, if the car doesn't have all of those features, it's not a ZHP-optioned 330?
Answer: Not necessarily. Customers could order the car with leather seats (option) and a perforated leather-wrapped M steering wheel (option). What's more, during the spring of 2005, BMW stopped putting Alcantara steering wheels on the ZHP (because of problems with premature wear), which means there are many ZHP-optioned cars on the road today without Alcantara steering wheels. Moreover, before BMW discontinued the Alcantara steering wheel, it also replaced many wheels under warranty, replacing them with leather wheels. Yet another reason why you'll find leather wheels coupled with Alcantara-clad seats. Additionally, while the trunk lid spoiler came standard, there was an option to have it deleted (option code 326). And this side note: some ZHPs, in early 2004, did not come with the trunk lid spoiler (even though customers did not choose option code 326) -- because of a parts shortage. Customers who complained eventually got them installed at the dealer at no cost (covered under warranty).

PDF file of C&D E90 330i 6MT test results (http://media.caranddriver.com/files/2006-bmw-330i2006-bmw-330i-specs.pdf)

Having owned both cars together for many years, the E90 feels like it has a broader torque curve in daily driving, but both feel very similar. The E90 gets better gas mileage.

FWIW, I think my ZHP was the C&D test car in that it has that "press package" option in the build sheet, is identical in options/color to the C&D test car, and before I bought it, it was owned by BMWNA. No sunroof = awesome headroom clearance when wearing a helmet (main reason I hunted forever to find an E90 M3 w/o sunroof). I bought it with 14k miles on it back in April 2005 with CPO warranty. By 20k miles the transmission was grinding 2nd and 3rd horribly which of course was replaced under warranty along with clutch/flywheel. My daughter owns the car now (and tracks/autocrosses it regularly).

I assume most of you drive the ZHP daily and that most (if not all) of you have driven normal 330's or other E46's. So, are we confirming that the ZHP rack is mechanically similar to the normal 330 rack. If not, is there truly any additional steering feel? And if so, is it really noticeable? Don't mean to pick a fight, I know this is a touchy subject on other BMW forums. I'm genuinely curious to hear from the people that experience ZHP steering the most
