    Everything You Know About The ZHP

    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).

    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.

    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

    I used to have a 2003 330Ci ZSP and I would argue it felt like it had a larger steering rack ratio than my current 2005 330Ci ZHP. But I can't confirm that claim though since I haven't driven my 2003 for three years.

    I had to dig around to find the VIN, but the build sheet states it was built 2003-01-16, so yeah, pre 3/03.

    Mine has no sunroof!
    My last e46 had one and the sun screen broke 3 times under warranty... I gave up trying to fix it.
    I also have rear PDC... I love it!
