H&R
H&R for Porsche
The year was 1980 – vehicle lowering was still completely unknown and a litre of gas cost only 1.15 DM.H&R company founders Werner Heine and Heinrich Remmen had a great vision: performance enhancement by lowering road cars with homologation. A sensation for that time and a forerunner of today’s lowering with part approval.The courageous young entrepreneurs soon realized that they had hit the mark with their project. Thanks to their ground-breaking idea, the company grew steadily into a well-established family business. Today, suspension components “Made by H&R” are deeply appreciated by Porsche customers all over the world.
Choosing the Right Fit for Your Porsche
Where H&R is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Suspension upgrades are often chosen to reduce roll, improve stance, and sharpen turn-in for fast-road driving where H&R parts are offered for Porsche models.
- Excessive roll, floaty damping, vague steering, and uneven tyre wear can indicate that a stock or existing setup may benefit from a correctly matched upgrade.
- Expect a slightly firmer, more controlled ride compared with many tired factory setups; alignment and geometry checks are important after changes.
- Plan for a proper four-wheel alignment (and corner balancing where applicable) once ride height and hardware are installed and settled.
- Match springs, bars, and dampers sensibly rather than mixing random components; start with clear goals (comfort, fast road, or track bias).
- After installing adjustable components, keep threaded adjusters clean and protected so future height or setup changes remain possible.

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Suspension Upgrades — Suspension upgrades are typically used to improve body control, cornering balance, and steering response on Porsche models, or to tailor the car for comfort, fast road, or track-day use where H&R components are available.
- Plan an alignment and geometry check after any significant change to ride height or key suspension hardware.
- Start with a clear goal for how you want the car to feel, then select springs, dampers, and bars to match.
Anti Roll Sway Bar — Anti-roll (sway) bars help reduce body roll and fine-tune handling balance on Porsche applications, and are often upgraded when owners want a flatter, more predictable feel or when existing components and bushes are worn.
- Consider renewing drop links and bushes at the same time as the bar to minimise noise and maximise improvement.
- Avoid extreme stiffness changes at one end only; handling balance front-to-rear is just as important as overall roll reduction.
Lowering Springs — Lowering springs are chosen to reduce ride height, sharpen response, and cut body roll, giving Porsche models a more purposeful stance where compatible H&R options are listed.
- Check whether shorter or matched dampers are recommended for the intended drop to maintain control and travel.
- Allow for a full alignment and, where appropriate, geometry correction to avoid premature tyre wear or instability.
H&R Adjustable Suspension Kits — H&R adjustable suspension kits provide height-adjustable, performance-focused suspension for supported Porsche models, allowing you to tune stance and body control within a tested range.
- Schedule a full four-wheel alignment after installation and consider corner balancing for the most consistent handling.
- Avoid extreme lowering settings; moderate, well-set ride heights usually ride and handle better in real-world use.
Wheel Accessories — Wheel accessories such as spacers, studs, and hardware are used to optimise stance, security, and wheel fitment on Porsche vehicles, and may be combined with H&R suspension changes where appropriate.
- Always confirm seat type, length, and hub-centric fitment for bolts, nuts, and spacers before installation.
- Use a torque wrench and re-check torque after initial driving to ensure hardware remains correctly seated.
