Product Details
The fully threaded shock body on these H&R Street Performance Coil Overs allows for precise height adjustment, which is key to lowering your 2005-2011 Porsche Boxster or Boxster S. This adjustment helps to lower the vehicle's center of gravity, leading to improved handling and better control on the road. These coil overs are custom valved to work with progressive rate springs, all designed and made in Germany to offer a balance of performance and ride comfort. They are a solid option if you're looking to fine-tune your suspension's feel and stance.
When installing these coil overs on a Porsche Boxster or Boxster S equipped with PASM (Porsche Active Suspension Management), please note that this system will disable the factory PASM functionality. The springs and dampers are specifically tuned to work together, providing a noticeable improvement in handling without sacrificing too much ride comfort for daily driving. The ability to adjust the ride height means you can dial in the perfect look and feel for your car, whether you're heading to a track day or just enjoying a spirited drive on your favorite roads.
This kit includes the front and rear coil over assemblies. Remember to consult the manufacturer's installation instructions for specific details on adjusting ride height and for any other necessary procedures. Proper alignment after installation is also recommended to ensure optimal performance and tire wear.
