ISC Suspension 06+ Lexus GS 300 N1 Basic Coilovers

This is the ISC Suspension N1 Basic Coilover kit for your 2007-2014 Lexus GS350. If you're looking to dial in your car's stance and handling, this kit is a solid option. It replaces your factory struts and springs with a complete, integrated coilover assembly, allowing for precise ride height adjustments and a more controlled feel on the road.

ISC Suspension built these N1 Basic coilovers with a focus on providing a noticeable improvement in handling without breaking the bank. They feature a monotube shock design, which generally offers better damping control and heat dissipation compared to twin-tube designs, especially during spirited driving. The spring rates are chosen to offer a good balance between comfort for daily driving and stiffness for better cornering performance. You can adjust the ride height independently of the spring preload, giving you the flexibility to set your car exactly how you want it, whether you're aiming for a subtle drop or a more aggressive stance. The top mounts are typically pillow ball or reinforced rubber, helping to transfer more feedback from the road to the driver.

This kit is designed as a direct replacement for your factory suspension components, meaning no welding or major modifications are usually required for installation. It's a popular choice for those who want to lower their GS and improve its responsiveness. Remember to have your alignment checked after installation to ensure optimal tire wear and handling characteristics.
