H&R 18-19 BMW 640i xDrive Gran Turismo G32 Sport Spring

What you get here are H&R Sport Springs, their most popular item, designed specifically for your 2018-2019 BMW 640i xDrive Gran Turismo. These springs are made from 54SiCr6 spring steel, which is shot peened for strength, making them both lightweight and resilient. They're built to lower your car's center of gravity, which not only reduces body roll for better handling but also closes up the gap between the fender and the tire for a sportier appearance.

The progressive spring rate is a key feature here. It means you get a comfortable ride during normal driving, but the springs stiffen up when you need them to during spirited driving or cornering. This design helps maintain superb ride quality while still improving how the car handles. Plus, by lowering the vehicle, you can also see a slight reduction in wind resistance, which may help with gas mileage.

If you're looking to give your 640i xGT a more dynamic feel and a lower stance, these springs are a solid choice. They are 100% made in Germany and are a well-known upgrade for improving a vehicle's driving experience.
