The Advantage of ISR Coilovers

These coilovers use monotube dampers, pillow-ball top mounts, and 32-way adjustable damping to give predictable response across different driving conditions. The spring rates are tuned for spirited street driving while remaining controllable on rougher pavement.

High-performance Japanese bearings and corrosion-resistant coatings help maintain long-term durability. You get sharper steering feedback and reduced body roll along with the ability to fine-tune the ride height so the car feels planted and balanced. These coilovers are for drivers who notice the difference in cornering and body control.

Pro Series Coilovers

Monotube dampers, pillow-ball mounts, and 32-way adjustable damping for precise handling and predictable body control on street or track.

Pro Series 2

Enhanced spring rates and revised valving for quicker response and finer tuning when you want sharper cornering without compromising everyday usability.

Basic Series

Height-adjustable coilovers that improve stance and handling without extreme stiffness, which is suitable for daily drivers.

True Coilover Conversions

Complete swaps for cars that need full coilover geometry instead of relying on modified stock suspension. Ideal for maximizing tuning flexibility and ride consistency.

How to Find the Ideal ISR Upgrades

The first step is to determine whether the vehicle be used more for daily driving, street runs, or track work. Your daily setups benefit from moderate spring rates and damping for comfort, while performance-focused builds can accept firmer settings for sharper cornering.

Check the fitment for your specific make and model to ensure all parts install cleanly. Remember that corrosion-resistant materials, camber adjustment, and damping range are key for long-term use and precise tuning. ISR coilovers let you achieve a balance between comfort, control, and adjustability.

Coilovers replace your factory struts and springs with a single adjustable unit that lets you control ride height, damping stiffness, and in some cases camber -- all from the same kit. Unlike lowering springs which are a fixed drop, coilovers give you the flexibility to adjust your setup as your needs change.

For street-driven cars the most important factors are adjustment range, ride quality at daily settings, and build quality of the hardware. For performance and track builds, spring rate and damping range become more critical. Most of the brands we carry target the street and occasional track day driver -- adjustable enough to dial in your setup, durable enough to last.

Frequently asked questions

What is the difference between coilovers and lowering springs?
Lowering springs drop your car a fixed amount and work with your existing shocks. Coilovers replace both the spring and shock as a single unit and let you adjust ride height and damping independently. Coilovers give you more control and are a better long-term investment if you plan to tune your suspension setup over time.

Are coilovers good for daily driving?
Street-oriented coilovers from brands like Tein, Riaction, and Godspeed are designed to be daily drivable. Set to a mid-range damping setting they ride noticeably better than most lowering springs while still giving you a lower, more controlled stance. Full track coilovers with very stiff spring rates are not comfortable for daily use.

How much do coilovers lower your car?
Most street coilovers allow between 1 and 3 inches of adjustment from stock ride height. The amount varies by vehicle and kit. Going too low can cause rubbing, poor suspension geometry, and increased wear. Most daily drivers aim for 1 to 1.5 inches of drop for a clean stance without sacrificing drivability.

Do I need an alignment after installing coilovers?
Yes, always. Any change to ride height affects your camber and toe settings. Installing coilovers without getting an alignment afterward will cause uneven tire wear and handling that pulls to one side. Budget for a 4-wheel alignment as part of the install cost.

What brands of coilovers does Redline360 carry?
We carry Tein, Godspeed, Riaction, Megan Racing, Truhart, Rev9, D2 Racing, Flatout, and more. Each brand has different strengths -- Tein is known for quality and reliability across a wide range of vehicles, Godspeed for value and wide fitment, and Riaction for 32-way adjustability at a competitive price point.
