Caster Camber Plates for 1993 Honda Civic Si

The top of the strut is the one place you can change camber and caster together, which makes it the most useful adjustment point on your Honda Civic's strut suspension.

It is also where the factory put a soft rubber mount that moves under load, so correcting the geometry and controlling it are the same job.

What Are Honda Civic Camber Plates

A camber plate replaces the standard strut top mount with one that lets the top of the strut sit in a different position.

Move the top of the strut inboard and the top of the wheel tilts inward, which is negative camber, and moving it outboard takes camber positive. Move it fore or aft and caster changes instead.

That is the entire principle behind how they work. The bottom of the strut stays located by the hub carrier, so moving the top is what changes the angle the whole assembly sits at.

Because the mount is a structural part of the suspension rather than a bracket, a plate also controls where that point stays under load, which is the half most people overlook.

How Do Honda Civic Camber Plates Work

Two approaches exist and they suit different purposes.

Slotted or fully adjustable camber plates use a movable upper bearing in a slotted housing, so the position can be changed by hand on an alignment rack. These give the widest range and suit track cars where the setting changes between events.

Offset plates and mounts place the strut's upper mounting point at a designed offset from standard, delivering a specific correction without on car adjustment. The offset is engineered for the application rather than dialed in.

Whiteline caster camber plates, listed in some catalogs as camber caster plates, are the offset type, built as complete strut mounts with the correction designed into the part. They go on, the alignment is set, and the geometry stays there.

The trade off between the two is straightforward. A slotted plate gives range and needs setting. An offset plate gives a known correction and needs nothing beyond fitting and aligning.

What Do Honda Civic Camber Plates Do for Handling

Three things change, and the second one is the one that sells the part.

Camber correction is the obvious change of the three. A lowered car runs more negative camber than the manufacturer intended, and a plate brings it back or dials it further depending on what the car needs.

Geometry control is the bigger gain underneath it. A factory strut mount contains soft rubber that compresses under cornering load, which means the top of the strut moves and the camber you set on the rack is not the camber the car has mid corner. A performance plate holds that point firmly, so the alignment reading and the actual behavior match.

Caster adjustment comes with the caster camber variants. More positive caster adds self centering, adds steering weight, and adds negative camber to the outside wheel through the turn, which is free grip exactly where it matters.

The combined effect is a front end that responds immediately and does the same thing every time.

Honda Civic Front Camber Plates and Why the Front Matters Most

Camber plates are a front suspension part on most applications, and there is a reason for that.

The front carries the steering, so geometry movement there shows up as vagueness in the thing the driver is holding. A rear wheel shifting its camber is a tire wear problem, and a front wheel doing it is a feel problem as well.

The front also does the work in a corner. Turn in, mid corner grip and braking stability all depend on the front tires having their contact patch where it should be when the load arrives.

Rear camber on multi link platforms is adjusted through arms and bushings instead, since there is no strut top to work from in the same way.

Honda Civic Camber Plates and Coilovers

Worth clarifying, since the two get bundled together constantly.

Many coilover kits include camber plates as part of the top mount, which is why searches pair them. The plate is doing the same job it would on a standard strut.

Where a coilover kit comes without them, a separate plate can usually be fitted, provided the mounting arrangement and the bearing match.

What a camber plate does not do is change ride height. That is the spring perch on a coilover, and the two adjustments are independent even though they live at the same end of the strut.

A car running coilovers without camber correction is often the one that needs it most, since a significant drop moves camber well beyond standard.

Honda Civic Camber Plates Against Camber Bolts and Offset Bushings

Three ways to correct camber on a strut car, and the right one depends on how far out you are.

A camber bolt gives a modest range using the existing hardware at the strut to hub joint. It is the cheapest option and it suits a car that has drifted out of specification or been lowered moderately.

Offset bushings move the control arm's inner pivot, which changes camber and often caster together. The range sits between a bolt and a plate, and the correction is built into the bushing rather than adjusted.

Camber plates work from the top of the strut, which gives the largest effect for a given amount of movement because the strut is long and the plate is at the far end of it.

The plate is also the only one of the three that improves how well the geometry is held, since it replaces the soft factory mount rather than working around it.

For a car needing a small correction, start with the bolt. For one that is lowered significantly or driven hard, the plate does more.

How Much Correction a Camber Plate Delivers

The figure depends on the design and on what the application allows.

An offset mount delivers a specific, engineered amount, chosen to suit the typical geometry change on that platform rather than to cover every scenario.

That matters when you are planning a build. A car lowered within normal ranges is what these are designed around, and one dropped to an extreme may need more than an offset can provide.

Caster correction usually comes alongside rather than independently, since moving the mounting point changes both angles together unless the design separates them.

Check your current alignment readings before ordering, since the correction needed is the gap between where the car sits and where it should be, not a number chosen in advance.

Have the alignment measured, choose the correction around the actual figures, and set it properly once fitted.

The Noise Trade Off

Being straight about this matters, because it is the one thing people are not expecting.

A factory strut mount uses rubber specifically to isolate road noise and vibration from the body. Replacing that rubber with something that holds position means more of what the suspension is doing reaches the cabin.

Expect more road noise, more sensation over expansion joints, and on some designs a degree of suspension noise that was not there before.

Spherical bearing plates transmit the most of any option. Offset mounts using a firmer bush sit between the factory part and a full spherical, which is why they suit a car that still gets driven on the road.

That trade is worth it on a car built for handling and worth thinking about on a daily driver.

Fitting Honda Civic Caster Camber Plates

The strut assembly has to come out, and the spring has to be released unless the strut is being replaced as a unit.

Compressed springs hold serious stored energy and releasing one unexpectedly causes severe injury, which is why this part of the job belongs with proper spring compressors or a pre assembled strut.

Replace the bump stop and dust boot while everything is apart. Both perish on the same timeline and both need the same access.

Use new top mount nuts where they are single use, which they frequently are.

Torque with the vehicle on its wheels at ride height rather than hanging, since the mount takes its set from the position it is clamped in.

Have the alignment set afterward without any exception. Fitting a correction part and not setting the result achieves nothing.

Checking and Maintaining Honda Civic Camber Plates

Performance mounts need looking at in a way factory ones do not.

Check for any play at the top of the strut periodically, particularly after track use. A bearing that has developed movement lets the geometry drift again.

Listen out for any change in the noise it makes. A knock or creak that was not there after fitting usually means the bearing has dried out or the mount has loosened.

Recheck the alignment after the first few hundred miles and after any serious track session, since the suspension settles and curb strikes move things.

On a slotted plate, confirm the adjustment has not shifted. On an offset mount there is nothing to move, which is part of the appeal for a road car.
