MODEL CAYMAN BOXSTER

Coilover setup for various use

Lowered Porsche 987 Cayman / Boxster
LPM coilovers - 5K front / 7K rear springs

Scope: 5 and 7 kgf/mm springs (approximately 280 and 392 lb/in). Suggested initial alignment targets for performance road tires. These are proposed tuning baselines, not Porsche factory specifications. Tire maker requirements, actual ride height, chassis condition and available adjustment take priority.

Alignment starting targets

Setting	Aggressive street	Track day	autocross
Front camber	-1.5 degrees	-2.5 degrees	-2.8 degrees
Rear camber	-1.8 degrees	-2.2 degrees	-2.0 degrees
Front TOTAL toe	0.04 degrees IN	0.00 degrees	0.06 degrees OUT
Rear TOTAL toe	0.20 degrees IN	0.16 degrees IN	0.12 degrees IN

Units: decimal degrees. Camber is per wheel, equal left/right. Toe is the sum across each axle: split equally left/right. For example, 0.20 degrees total rear toe-in means 0.10 degrees per wheel. IN and OUT state direction; do not rely on machine sign conventions.

Caster: use the correct factory specification for the model year and suspension, with left/right matched as closely as practical. Set rear thrust angle as close to zero as practical.

1 / Aggressive street

Prioritize straight-line stability, braking confidence and compliance on uneven pavement. The mild front toe-in is deliberate. Inspect inner shoulders regularly; reduce camber if road mileage and wear indicate the need.

2 / Track day

Additional front camber supports sustained cornering; zero front toe limits scrub and keeps the car predictable. Retain rear toe-in for stability. Refine camber using hot tire temperatures, wear and the tire manufacturer's guidance. Camber plates or adjustable lower control arms may be needed to reach these targets. Do not sacrifice rear toe to achieve more camber.

3 / autocross

Slight front toe-out helps response in short transitions. Keep rear toe-in as a conservative starting point. Return to the street toe setting for regular road use. Use zero front toe on a dual-purpose car if frequent realignment is impractical.

Damper settings & setup process

Use the 5K front / 7K rear spring package for all three baselines. More damping does not automatically mean more grip.

Provisional damper starting settings

The following are experimental starting settings, not manufacturer-validated presets. Confirm the soft direction and permitted adjustment range from the instructions supplied with your kit before using click counts.

Use	Front	Rear
Aggressive street	8 clicks from full soft	10 clicks from full soft
Track day	12 clicks from full soft	14 clicks from full soft
autocross	10 clicks from full soft	12 clicks from full soft

Counting: full soft is zero; each detent toward firm adds one. Approach the stop gently and never force or turn beyond the permitted range. Keep both dampers on an axle equal. Do not assume clockwise is firm without checking your kit. If your adjusters differ from the listed 30-position system, obtain a kit-specific baseline.

Tune in small steps

Change one axle by 1-2 clicks, then repeat the same road section or session. Log settings, tire pressures, surface conditions and behavior. For rough or wet conditions, try 2 clicks softer on both axles and reassess. autocross on broken pavement may need the street damping baseline. If the tires skip or grip worsens over bumps, soften the affected axle. If body motion continues oscillating after a disturbance, try 1-2 clicks firmer. Address steady-state balance through tires, alignment, springs and sway bars rather than relying on dampers alone.

Fitment, height and alignment

These settings cover the 5K/7K package only. Cayman PO-03, Boxster PO-10-1 and original-upper-mount Boxster PO-10 have application-specific mount and spring details; follow the instructions for your kit. Original mounts may limit attainable camber. Resolve PASM compatibility with the specified delete/coding solution where fitted.

Set preload and body length to LPM instructions; retain adequate bump and droop travel. At full steering lock and suspension travel, check tire clearance, brake hoses, spring seating and ball-joint articulation. Check bump steer on a substantially lowered car. There is no universal safe fender-height target across 987 models and tire sizes.

With driver ballast and representative fuel, settle the suspension, set ride height and corner balance, then complete a four-wheel alignment. Recheck toe after any camber or height change. Verify hardware torque and alignment after the installation has settled. Use closed-course testing to evaluate track and autocross settings.

Levinson Performance Coilover Suspension
Cayman / Boxster models '05-'12

Comfortable road trips, spirited weekends or track days? Start with how you want the car to feel in our Coilover Setup Guide.

Engineered for Drivers Who Demand More

THIS ITEM IS BUILT TO ORDER AND WILL TAKE 2 WEEKS FROM DATE OF ORDER BEFORE SHIPPING.

The Levinson Performance Coilover System was developed for Porsche enthusiasts who expect exceptional handling, precise chassis control, and outstanding ride quality without compromise.

Rather than offering an off-the-shelf suspension, Levinson Performance partnered with one of Taiwan’s most respected suspension engineering and manufacturing companies, an OEM supplier with decades of experience producing premium suspension components for performance automotive brands worldwide. Every application is engineered specifically for its chassis with carefully selected spring rates, damper valving, and ride height ranges that complement the vehicle instead of forcing a one-size-fits-all solution.

Whether your Porsche is a daily driver, weekend canyon carver, autocross competitor, HPDE machine, or dedicated race car, the LPM Coilover System delivers sharper response, greater confidence, and exceptional composure while allowing the suspension to be tailored to your driving style through adjustable damping and optional spring rates.

Advanced Digressive Damping Technology

At the heart of every LPM Coilover is advanced digressive damper valving, a design favored in high-performance street and motorsport applications because it delivers exceptional body control without the harsh ride commonly associated with aggressive coilover systems.

Unlike conventional dampers that continuously increase resistance as suspension speed rises, digressive valving generates high damping force during low-speed suspension movement, then transitions to a flatter damping curve during high-speed impacts.

The result is a suspension that behaves differently depending on what the car is doing.

Exceptional Chassis Control

During cornering, braking, acceleration, and steering inputs, suspension movement occurs at relatively low shaft speeds.

In these conditions, the digressive valving produces firm damping forces that keep the chassis composed and predictable.

Benefits include:

Sharper steering response
Faster turn-in
Reduced body roll
Improved braking stability
Better weight transfer control
Increased driver confidence

Outstanding Ride Quality

When the suspension encounters potholes, expansion joints, rough pavement, or track curbing, shaft speeds increase dramatically.

Instead of becoming increasingly harsh, the digressive valve design reaches a controlled blow-off point where additional damping force increases very little. This allows the suspension to absorb sharp impacts while maintaining excellent wheel control, significantly reducing the harshness often associated with traditional performance coilovers.

The result is a suspension that feels remarkably composed during aggressive driving while remaining comfortable enough for everyday use.

Tuned for Your Driving Style

Every LPM Coilover features 30-position damping adjustment, allowing you to fine-tune suspension behavior for virtually any driving environment.

Choose softer settings for comfortable daily driving or increase damping for spirited mountain roads, autocross competition, track days, or dedicated race use.

To further tailor the suspension to your specific needs, optional spring rates are available for customers seeking a setup optimized for street driving, dual-purpose performance, or full competition use.

One suspension platform, multiple personalities.

NOTE: If equipped with PASM, must be deactivated and coded out.
