DIALED IN: COILOVER SETTINGS FOR STREET AND TRACK
Coilovers have the potential to completely change your driving experience, but only if they’re set up the right way. Whether you're after sharper handling, a better stance, or just tired of the floaty stock suspension, dialing them in matters. Street and track setups aren’t the same. What feels smooth and planted on your commute might fall apart under pressure at speed. And that stiff track setting? Perfect for lap times, but makes for a brutal morning commute. In this post, we’ll break down how to tweak your coilovers for the street, the track, and how to find a middle ground that won’t beat you up in between.
BEFORE YOU START ADJUSTING
Coilovers give you more control over how your car handles, feels, and sits. But unlocking that control means understanding what each adjustment actually does. Let’s break down the main adjustments:
Ride height - Adjusts how low (or high) your car sits. This affects center of gravity, suspension travel, and even alignment.
Damping - Controls how fast the shock moves. Compression affects how the suspension reacts when the car hits a bump; rebound controls how it recovers afterward.
Preload - Changes the amount of tension on the spring when the suspension is fully extended. It won’t raise or lower the car on its own, but it can affect how quickly the spring reacts.
Camber plates - If included, these let you fine-tune how much your wheels tilt inward or outward (camber) by adjusting the coilover top mounts. They’re great for dialing in better handling without messing with factory suspension parts.
EVERYDAY SETTINGS THAT WORK
For everyday driving, the goal is a setup that feels good, handles well, and doesn’t beat you up on rough roads. Softer damping helps the suspension absorb bumps without feeling too floaty. To get there, dial in softer damping so the suspension soaks up bumps instead of bouncing over them. Keep your ride height moderate; not too low to avoid rubbing, but low enough to help with handling. Set preload close to the factory baseline; this keeps your springs reacting naturally without making things harsh.
TRACK SETTINGS THAT DELIVER
When you’re headed to the track, it’s all about grip, quick response, and cutting down body roll. Firmer damping helps keep the car planted and lets it react faster to what you’re doing behind the wheel. You’ll want to drop the ride height a bit; just not so much that you start rubbing or bottoming out. A little extra preload can also help the car feel more responsive, especially in fast corners or quick transitions.
Tweak rebound and compression based on feedback from the car and tires; some of it only shows up at speed.
FROM STREET TO TRACK AND BACK
Swapping between street and track setups is easier when you start with a solid baseline. In most cases, this means a street-friendly configuration that balances comfort and control for daily driving. From there, you can fine-tune a more aggressive setup for track days, then return to your original settings when you're back on the street. Mark your adjusters and record how many clicks or turns you’ve made so you can easily switch back and forth. With a bit of practice, the whole process usually takes 15 to 30 minutes. Small changes can make a noticeable difference, so take the time to experiment and find what works best for your driving style as well as the layout of the course.

DIALING IN YOUR IAG SPEC COILOVERS
Need help dialing in your IAG Spec Street Series Coilovers? Every car is different, so start with small adjustments and see how your car responds. A good starting point for a sporty street setup is roughly 12 clicks from soft in the rear (halfway through the 24-click range) and about 10 clicks from soft in the front. On our Subaru STI, a ride height around 1.5 inches lower than stock delivers a responsive, controlled feel without sacrificing comfort—a .75–1.5 inch drop from stock is usually a solid place to start. When heading to the track, firm up the damping a few clicks at a time—on our setup, an additional 4 clicks improved handling and cornering response.
Comfort and performance don’t have to be at odds. With the right components and a few smart adjustments, your suspension setup can strike a solid balance between daily drivability and weekend performance.
