H&R Height Adjustable Spring Kit Porsche Boxster/Cayman 981/718 – 23006-1
The H&R Height Adjustable Spring Kit is designed for Porsche 718 Boxster and Cayman models and works with the original shock absorbers, including cars with electronic damping.
What this kit does
This kit replaces your standard springs with height adjustable springs. You keep your original shock absorbers and all factory electronics, including adaptive or PASM-style damping where fitted.
You can set the ride height within an approved range, so you choose how low you want the car to sit, within safe limits.
- Gives a lower, more purposeful stance
- Improves cornering and steering response
- Keeps full function of factory electronic dampers where fitted
Why it matters for your 718
From the factory, the 718 Boxster and Cayman sit relatively high for road use. By lowering the centre of gravity, the car rolls less in corners and feels more stable at higher speeds. Turn-in becomes sharper and the car feels more connected to the road.
Because you keep the original shock absorbers, ride comfort remains close to standard, especially in Comfort mode on adaptive cars. In Sport modes, you get a firmer, more focused feel without making the car harsh for normal driving.
Key features
Within the tested range, this kit allows:
- Front axle lowering: approx. 10 – 25 mm
- Rear axle lowering: approx. 20 mm
- Stepless (fine) height adjustment within the approved range
The springs are engineered by H&R in Germany with a parts certificate, so you know the setup has been tested for your car. The kit is made to work with original dampers with or without electronic adjustment (check the application details for your exact model).
Important: Ride height should always be set and checked by a competent workshop, with a proper wheel alignment carried out afterwards.
