What is the benefit of a progressive spring rate?

A progressive spring rate means the springs are softer during normal driving for a comfortable ride, but become stiffer as they compress further. This provides better handling and reduced body roll during spirited driving or cornering without sacrificing everyday comfort.

Do these springs work with PASM?

Yes, these H&R Sport Springs are designed to be compatible with Porsche's Active Suspension Management (PASM) system on the 2005-2011 Boxster models.

What is the expected ride height reduction?

These Sport Springs are designed to reduce the vehicle's fender well gap, lowering the center of gravity for improved handling. Specific measurements for ride height reduction are not provided, but they are H&R's most popular lowering spring kit.

Product Details

Built from 54SiCr6 spring steel, these H&R Sport Springs are shot peened for added strength and resilience, making them a strong and lightweight choice for your 2005-2011 Porsche Boxster or Boxster S. These springs are designed to lower your vehicle's center of gravity, which directly translates to reduced body roll and more responsive handling when you're on the road.

The progressive spring rate is a key feature here. It means the springs offer a comfortable ride during normal driving, but stiffen up when you need them to during spirited driving or cornering. This design helps maintain superb ride quality without sacrificing performance. H&R's Sport Springs are their most popular product, and for good reason – they offer a noticeable improvement in how the car looks and handles, with a lower wind resistance signature that can also help with gas mileage.

This kit is made in Germany and is designed to fit models equipped with PASM (Porsche Active Suspension Management). If you're looking to give your Boxster a sportier stance and more engaging driving experience, these springs are a solid option.
