PrecisionDrop Kits
We engineer precision static drops and coilover conversions in our Irving bay — lowering your center of gravity while calculating exact damper stroke to maintain travel over rough Dallas-Fort Worth pavement. Progressive spring rates, negative camber correction, and full-contact-patch geometry so your car handles better dropped than it did at stock height.
Drop Kit Tiers
Every build starts with a baseline geometry audit — not a one-size-fits-all spring swap. We spec the right tier for your chassis.
Progressive Static Drop
Cold-wound progressive-rate lowering springs (Eibach Pro-Kit or H&R Sport) on your factory struts. We measure piston stroke at the new ride height and trim bump stops to retain minimum 2.0" of compression travel. The entry point for a clean drop without replacing your entire suspension.
Matched Drop & Camber Correction
Progressive springs paired with shortened monotube dampers (Bilstein B8s) valved for reduced stroke. Includes SPC adjustable control arms or eccentric bolts to correct negative camber for daily-driven enthusiast cars.
Full Coilover Conversion & Corner Balance
Fully threaded coilovers (KW Variant 3 or BC Racing BR) with independent height and damping adjustment. Includes chassis-specific spring rates, spherical camber plates, and four-wheel corner balancing for equalized weight distribution.
The Metroplex Advantage
Why Choose
Metroplex?
Lowering a car alters your roll center and bushing geometry. We engineer the entire kinematic chain so your chassis handles better, wears tires evenly, and rides smooth over Dallas-Fort Worth pavement.
Static-Load Bushing Clocking
We torque all suspension pivot bolts at full curb weight on our alignment rack, never while hanging on a lift. This prevents torsional preload that cracks bushings prematurely in Texas heat.
Hunter HawkEye Elite Alignment
Our in-house Hunter HawkEye Elite measures geometry to the hundredth of a degree. We adjust camber and tie rods to neutralize negative camber and eliminate bump steer.
Thread Prep & Anti-Seize Protocol
We replace factory hardware with Grade 8/10.9 fasteners coated in Permatex Copper Anti-Seize. Coilover collars receive Boeshield T-9 to prevent galvanic corrosion from Texas soil.
On drops exceeding 1.5 inches, extended ball joints or bump-steer kits are often required to prevent violent tramlining. We assess every chassis's kinematics before installation.
The Process
Geometry Audit & Teardown
Measure factory ride height at all four corners, extract factory struts/assemblies using Branick spring compressors, and dissolve seized hardware with Kano Kroil penetrant.
Component Prep & Mock-Up
Bench-set coilover preload with digital calipers for matched left-to-right geometry. Static drop springs indexed to shortened dampers. All pivot points left finger-tight for static-load torquing.
Static-Load Torquing
Vehicle lowered onto alignment slip plates at full curb weight. All pivot hardware torqued to exact OEM specs with calibrated Snap-on wrenches — zero bushing bind.
Alignment & Road Test
Full Hunter HawkEye Elite custom alignment to eliminate negative camber, followed by road testing over rough pavement near our Irving bay to verify damper recovery and ride quality.
Avoid These Pitfalls
Common Mistakes We Fix
We regularly correct cars that were dropped incorrectly by other shops or DIY installs. These are the failures that roll into our Irving bay most often.
Thermal Spring Shortening (Torch Cutting)
Torch-heating factory springs destroys the steel's temper, creating dead coils prone to snapping under load. We only install purpose-built progressive-rate springs from Eibach, H&R, or equivalent.
Neglecting Bump Stops & Piston Travel
Drop springs on full-length factory struts force the piston to bottom out — one hard pothole blows the nitrogen seals. We measure piston stroke and trim bump stops on every build.
Ignoring Induced Negative Camber
Uncorrected negative camber from a drop eats through tire inner edges in under 5,000 miles and increases hydroplaning risk. We install adjustable control arms or offset bushings to restore full-width contact.
Torquing Bolts on the Lift — Not at Ride Height
Bolts torqued on the lift lock torsional preload into bushings — they crack within months in Dallas-Fort Worth heat. We torque everything at full curb weight on the alignment rack.
