Exciting styling and exciting handling. These two traits arguably more than any others, define two-seater sports cars. Cars like the BMW Z4. Having a vehicle that looks the part and can string together a great piece of road with stability and accuracy makes every drive an adventure. Whether carving through alpine passes or simply sat in a lowly car park, having a proper suspension setup really can change the way you feel for your vehicle.
Lowering springs may be at the lower end of the budget spectrum when it comes to suspension mods, but they are possibly the best value improvement that can be made to any sports car. A subtle drop in ride height, paired with increased spring rates makes for a better handling car with increased road presence to boot.
Springs kits, such as those featured below, come with a variety of ride heights and spring rates. Ensuring the correct kit is purchased for the correct vehicle can be difficult, but get it right and the results, for an admirably small outlay, can be extremely dramatic.
Things to Consider Before Purchasing
Vehicle Compatibility
Suspension parts are notoriously complex and hence, are specific to every model of vehicle. Some cars, the BMW Z4 included, may even run different suspension springs between engine variants and body styles.
Using the correct subheadings and links below will help guide towards the correct parts for the year, body and engine variant required.
Ride Height
The main variable when choosing lowering springs will be the reduction in overall ride height. Those seeking that ultimate stance and road presence will most-often opt for springs that give the largest drop. This may not always be the smartest choice however, as spring rates will need to be increased as a result of large decreases in suspension height, often leading to a more uncomfortable ride, as well as creating a car that may have difficulty climbing the UK’s notoriously gratuitous speed bumps.
Before purchasing we would recommend deciding whether the looks or drivability of the vehicle will be more important. Look to forums and fan websites to see examples and feedback for Z4’s with ride heights reduced by varying amounts.
Corrosion Protection
UK roads are known for being salt-laden, for large portions of the year. Couple this with regular downpours and metal suspension parts can often corrode, degrade and even fail within a few years of fitting.
Particularly cheap lowering springs will often come unprotected, meaning at least a layer or two of paint would be advisable. Higher end products generally come coated in protective layers, while also being backed by manufacturers warranties.

The Best BMW Z4 E85 (2002-2008) Lowering Springs on the Market
Eibach Pro Kit Lowering Springs E10-20-010-01-22
Check the latest price on eBay
Eibach pro kits are known across the industry for offering subtle ride height drops, while maintaining excellent levels of comfort and cockpit NVH. BMW Z4’s are vehicles that already ride fairly low to the ground, negating the need for large reductions in ride height for most owners. This means that the smaller drop in ride height, paired with neatly refined spring rates will likely give the best overall improvement, arguably of any kits listed. In fact, the all-round improvement and quality of these parts often lead to OEM brands offering Eibach pro kits from authorised dealers without voiding the cars warranty.
This Eibach kit is not only backed by the brands reputation but also their own 5-year warranty. This, along with thousands of glowing customer reviews should give good confidence if choosing Eibach.
Part reference: E10-20-010-01-22

Pros:
- Subtle drop in overall vehicle ride height

The second kit featured here is the Direnza lowering spring kit. Offering a similar drop to that of the Eibach pro kit, this offering is not only budget friendly but should also give that optimised look and road presence desired by many Z4 owners. The reduction in ride height is paired with increased springs rates to add much desired stiffness and improved handling characteristics. Direnza springs may be tested on the track first, but they also promise to be highly suited for the road, improving handling without creating an uncomfortable or unruly vehicle to drive.
Direnza springs are made from corrosion resistant materials and coated with bright red paintwork, for further protection from harsh UK winters. The parts are also covered by the manufacturers 5-year warranty.

H&R Sport Lowering Springs 29269-1
Check the latest price on eBay
Last but by no means least we have the H&R lowering spring kit. H&R always seem to take their lowered ride heights a little more seriously than rivals, to give that extra 5/10mm drop in ride height, allowing customers to achieve their desired look and fitment. The lower ride height achieved is sure to bring down the vehicles centre of gravity which, when paired with stiffer spring rates, will give improved turn in and feel through the steering. A progressive spring design is implemented here too, to attempt to take the worst out of the craters we often refer to as potholes, here in the UK.
A lifetime manufacturer’s warranty (for the initial purchaser) is certainly nothing to be ignored, signalling H&R’s intent to make high quality and long-lasting suspension components. Corrosion resistance measures help ensure this promised longevity through the use of powder coating.
Part reference: 29269-1
Ride height reduction: 35mm front & rear
Warranty: Lifetime

- Lifetime warranty
- Bigger ride height decreases when compared to other featured spring kits

In Conclusion
While the BMW Z4, in any model year and engine variant, is a great all-round sports car, they are often criticised for leaning more towards the GT spectrum, than all-out performance vehicle. This leaves scope for serious improvement of the handling to create a more responsive vehicle, albeit one that may incur a little extra noise and vibration (though some may say this further adds to the experience of this type of vehicle).
Lowering springs can not only bring about an improvement in handling characteristics but can also vastly change the overall look of any car. Wheels sat further into the arches, with less dead space and a more meaningful look. For a relatively modest outlay, lowering springs could be just the modification for your Z4, to re-ignite your love for the car and take both the performance and looks to the next level.
