How to Adjust Toda Fightex Coilovers: What You Need to Know

The Toda Fightex is a performance coilover suspension system built primarily for Honda and Acura platforms. It's designed for drivers who want more control over ride height, damping stiffness, and overall suspension behavior than a stock setup provides. Adjusting it correctly isn't complicated once you understand what each adjustment does — but getting the settings wrong can affect handling, tire wear, and ride quality in ways that aren't always obvious until you're on the road.

What the Toda Fightex Actually Adjusts

The Fightex is a full coilover kit, meaning the spring and shock absorber are integrated into a single unit. This gives you multiple points of adjustment that stock suspension doesn't offer:

• Ride height — controlled by raising or lowering the lower perch on the coilover body
• Damping force — controlled by a numbered dial typically located at the top of the shock body or reservoir
• Spring preload — the tension applied to the spring before it's compressed under load

Each of these adjustments is independent, which is both the appeal and the complexity of a system like this. Changing one can affect how the others behave in practice.

Adjusting Ride Height

Ride height on the Fightex is set by threading the lower spring perch up or down along the coilover body. Here's how the process generally works:

1. Loosen the lock ring — there's a locking collar that holds the spring perch in place. You'll need a spanner wrench (usually included with the kit or sold separately).
2. Thread the perch up or down — moving it up raises the car; moving it down lowers it.
3. Re-tighten the lock ring — this prevents the perch from moving under load.
4. Re-measure ride height at all four corners after the car has been set back on the ground and allowed to settle.

A few things to keep in mind: both sides of an axle should be set to the same measurement to avoid a lopsided stance or uneven handling. After any ride height change, a wheel alignment is required — camber, toe, and sometimes caster will shift when ride height changes, and driving on misaligned wheels causes accelerated and uneven tire wear.

Adjusting Damping Force 🔧

Damping controls how quickly the shock absorber responds to compression and rebound — essentially, how stiff or soft the suspension feels in motion. The Fightex uses a numbered click system, typically ranging from full soft to full stiff.

To adjust damping:

• Locate the adjustment dial on the shock body (placement varies by application — some are top-mounted, some are on a remote reservoir)
• Turn the dial to increase or decrease stiffness; the clicks are numbered so you can track your setting
• Adjust all four corners, noting each setting so you can return to a baseline if needed

A common starting point recommended in many track-day communities is to set all four corners to the middle of the adjustment range, then tune from there based on feel and use. Stiffer settings improve body roll control and cornering response but increase harshness over bumps. Softer settings improve ride comfort and bump absorption but can make the car feel floaty under hard cornering.

Street use, track use, road surface quality, and driver preference all affect what "right" actually feels like.

Spring Preload: What It Is and When to Adjust It

Preload is the amount of tension on the spring when the suspension is at full droop (fully extended). It's set by the position of the upper spring seat relative to the lower perch. Too little preload can allow the spring to rattle or move freely. Too much preload stiffens the effective spring rate and raises ride height even without moving the perch.

On the Fightex, preload is typically minimal by design — the springs are meant to work under load from the car's weight, not from artificial tension. In most street setups, preload isn't the primary adjustment to chase. If you're hearing spring noise or noticing unusual behavior at full droop (like over a speed bump or on a lift), preload is worth checking.

Variables That Shape the Right Settings

No single set of numbers applies to every Fightex install. What works depends heavily on:

After You Adjust: What to Check

Any significant adjustment — especially ride height — should be followed by:

• A professional wheel alignment at a shop familiar with performance setups
• A test drive on varied surfaces to evaluate comfort and stability
• A visual check that lock rings are tight and nothing has shifted after the first few miles

Some drivers also find it helpful to keep a written log of each change and the conditions tested under — it's easy to lose track of what setting produced what result, especially when adjusting multiple variables at once. 🔩

The Part That Depends on Your Situation

The Fightex is designed to be tunable, but the "correct" adjustment is a moving target. It's shaped by your specific vehicle's geometry and weight, what springs came with your kit (rates vary by application), what you're trying to achieve behind the wheel, and whether you're also running any other suspension modifications. Two drivers with the same car and the same coilovers can arrive at completely different settings and both be right — for their driving style, their roads, and their goals.
