Frequently Asked Questions

Yes. The 23037-4 springs are engineered to work directly with the BMW M5 Touring G99 OEM adaptive shock absorbers. You do not need to replace the dampers, and all electronic adaptive damping modes including Sport, Sport Plus, and Comfort remain fully functional after installation.

The 23037-4 provides a front drop of 25 to 35 mm (approximately 1.0 to 1.4 inches) and a rear drop of 20 to 30 mm (approximately 0.8 to 1.2 inches). The VTF design lets you fine-tune within that range by adjusting the spring perch position during installation.

Yes. The 23037-4 is TUV-approved and ships with an official parts certificate. This certification confirms the springs meet German road safety standards and are legal for use on public roads in Germany and many other European markets.

It does. The G99 M5 Touring carries the added weight of the hybrid battery pack and electric drive components, which influences axle loads significantly. H&R engineered the 23037-4 specifically for the G99 platform, with load ratings of up to 1,475 kg at the front axle and up to 1,670 kg at the rear axle to accommodate the PHEV drivetrain mass.

Yes. VTF (Variable Track Force) springs feature an adjustable spring perch that allows you to fine-tune ride height within the rated lowering range without removing the springs. This makes corner balancing and stance adjustment straightforward once the system is on the car.

Installing aftermarket springs may affect the portion of your BMW factory warranty related to suspension components. We recommend consulting your dealer before installation. The H&R 23037-4 itself is covered by H&R's limited lifetime warranty against manufacturing defects.

Yes. Any ride height change on a vehicle with independent suspension requires a four-wheel alignment to restore proper camber, caster, and toe settings. This is especially important on the M5 Touring G99, which uses a sophisticated multi-link rear suspension. We strongly recommend a professional alignment immediately after installation.

Standard H&R sport springs offer a fixed spring seat position and a single lowering value determined at the factory. VTF (Variable Track Force) springs incorporate an adjustable perch that allows the installer to select a specific drop within the rated range. On the 23037-4, this means you can run 25 mm of front drop for a mild stance or dial up to 35 mm for a more aggressive look, all from the same spring set.

Installation requires a spring compressor rated for the M5 Touring's spring rates, a torque wrench, standard metric sockets and ratchets, and a hydraulic floor jack with jack stands. Given the complexity of the M5 Touring's adaptive suspension system and the weight of the PHEV platform, professional installation by a shop familiar with BMW air and adaptive suspension systems is strongly recommended.

Installation Overview

1. Safely lift the vehicle and support it on jack stands at the designated chassis points.
2. Remove the front and rear wheels to access the suspension strut and shock assemblies.
3. Using a spring compressor, carefully compress the existing OEM springs before removing the strut top mounts.
4. Remove the OEM springs and transfer the factory bump stops and spring seats to the new H&R 23037-4 springs.
5. Set the adjustable spring perch to your desired lowering position within the rated range before reassembly.
6. Reassemble the strut or shock assembly using the OEM adaptive dampers and torque all fasteners to BMW factory specifications.
7. Reinstall wheels and torque lug bolts to specification.
8. Lower the vehicle and perform a full four-wheel alignment before driving.
9. Recheck all suspension fastener torque values after the first 100 miles of driving.
