911 993 C2 / C4
LPM Street springs: 7.02K front / 8.36K rear

Applications: PO-11. K denotes kgf/mm. Suggested initial targets for performance road tires. These are proposed tuning baselines, not Porsche factory specifications. Tire requirements, actual ride height and available adjustment take priority.

Alignment starting targets

Setting (degrees)	Aggressive street	Track day	autocross
Front camber	-1.5	-2.5	-2.7
Rear camber	-1.8	-2.2	-2.0
Front TOTAL toe	0.04 IN	0.00	0.04 OUT
Rear TOTAL toe	0.24 IN	0.20 IN	0.18 IN

Units: decimal degrees. Camber is per wheel, matched left/right. Toe is TOTAL across each axle, divided equally left/right. For example, 0.20 total rear toe-in means 0.10 per wheel. IN and OUT specify direction independently of machine sign conventions.

Caster: use the correct factory specification for the exact model year and suspension. Match left/right as closely as practical; set rear thrust angle near zero. If a target exceeds the available range, retain correct toe and an even alignment rather than forcing it.

1 / Aggressive street

Prioritize stability, braking and compliance on uneven pavement. Inspect inner-shoulder wear and revise camber for actual road mileage and tire behavior.

2 / Track day

Use tire temperatures and shoulder wear to refine camber. Preserve rear toe-in. Additional camber adjustment hardware may be needed. Do not sacrifice rear toe to obtain more negative camber.

3 / autocross

Small front toe-out improves initial response; retain rear toe-in. Return to street toe for regular road use, or use zero front toe if frequent realignment is impractical.

Provisional damper starting settings

These are experimental starting settings, not manufacturer-validated presets. They are not calculated from spring rates. Confirm the soft direction, adjuster type and permitted range in the instructions supplied with your specific 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; never force it or turn beyond the permitted range. Keep both sides of each axle equal. Do not assume clockwise is firm. If your kit has a different adjustment system, obtain its specific baseline instead of applying these counts.

Tune in small steps

Change one axle by 1-2 clicks, then repeat the same route or session. Log settings, tire pressures, surface and behavior. Try 2 clicks softer on both axles for rough or wet conditions and reassess. If tires skip over bumps, soften the affected axle. If body motion keeps oscillating after a disturbance, try 1-2 clicks firmer. Address steady-state balance through tires, alignment, springs and sway bars; more damping does not automatically mean more grip.

Application and spring configuration

Spring codes are 200-07 front / 200-08 rear. Retain rear toe-in and check toe change through suspension travel. Excessive lowering can reduce travel and exceed the standard adjustment range.

Set height before alignment

Set preload and body length to the kit instructions. Preserve bump and droop travel; check spring seating, tire clearance, brake hoses and joint articulation at full steering lock and suspension travel. Check bump steer on a substantially lowered car. There is no universal fender-height target across these models and tire sizes.

With driver ballast and representative fuel or operating load, settle the suspension, set height and corner balance where applicable, then align all four wheels. Recheck toe after camber or height changes. Verify torque and alignment after settling. Complete applicable PASM, air-suspension, steering, headlamp and driver-assistance procedures for the equipment fitted. Evaluate track and autocross settings on a closed course.

Levinson Performance Coilover Suspension

Part number / SKU: PO-11.

Engineered for Drivers Who Demand More

THIS ITEM IS BUILT TO ORDER AND WILL TAKE 2-4 WEEKS 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.

Premium Engineering Throughout

Every component is selected for durability, precision, and long-term reliability.

30-Position Adjustable Damping

Thirty precisely indexed damping settings provide a wide adjustment range to fine-tune ride quality, chassis balance, and handling response.
