ISC Suspension 06-11 BMW 3 Series E90/E91/E92 N1 Basic Coilovers - Track/Race

The springs in this ISC Suspension coilover kit are made from SAE9254 steel, a material known for its strength and resilience. They've been tested over 500,000 times to ensure they deform less than 5%, meaning they'll hold their shape and performance characteristics even under demanding conditions. This kit is designed for a range of BMW 3 Series models from 2006 to 2011, including popular choices like the E90, E91, and E92 chassis. It's a solid option if you're looking to significantly improve your vehicle's handling and stance, whether for spirited street driving or occasional track use.

ISC Suspension builds these coilovers with a single cylinder monotube design, which helps maintain consistent damping performance. You get 32 levels of adjustment for both rebound and compression, allowing you to fine-tune the ride quality and how the car responds to the road. A key benefit is that the spring preload adjustment is separate from the ride height adjustment. This means you can lower your car considerably without negatively impacting how comfortable the ride feels. The top mounts use rubber bushings, which help isolate road noise and vibrations, making for a more comfortable experience on the street compared to solid pillowball mounts.

Included with this kit are ISC Coilover Covers, made from 3mm neoprene, to protect the coilovers from dirt and debris, helping to ensure smooth height adjustments over time. You'll also find copper-based anti-seize lubricant in the box to make installation easier and protect the threads. ISC Suspension backs these coilovers with a Limited Lifetime Warranty to the original owner, which speaks to their confidence in the build quality and durability of the product.
