Chassis alignment scanning and bench fabrication guarantee true fitment before delivery.
Factorys Five supplies engineered automotive build kits, turbo kit fabrication packages, and custom exhaust components directly to sports car fabricators and race teams across the United States. Every critical flange, intake tract, and suspension pick-up point is validated against real tubular jigs inside our Wareham machine shop.
Pricing Scope & Basis: Performance components range from $5.99 to $629.99 USD per retail unit, with a catalog average of $324.97 USD. Pricing is inquiry-only and determined by vehicle make and model, required fitment tolerances, build tier, local Wareham stock availability, and overall kit volume. Shop bench installation is quoted strictly as a separate service line item.
Chassis coordinate laser scanning for a tube-frame roadster project in Plymouth County
The project arrived with an aftermarket space-frame that had experienced minor heat distortion during secondary cage gusseting. The builder needed front tubular upper and lower control arms that matched original steering rack geometry while clearing a dry-sump oil pump belt drive. Rather than guessing with string lines and slotted holes, we placed the rolling chassis on our cast-iron surface plate and conducted a three-dimensional coordinate scan across all eight suspension hard points.
We discovered an 8.2 mm outward offset on the passenger rear control arm bracket that would have induced severe bump steer under heavy compression braking. Our machine shop engineered asymmetric chromoly arms with stepped 6061-T6 aluminum shims, restoring mechanical roll centers to within 0.15 mm of factory theoretical design. We provide this dimensional verification so builders never have to re-weld welded brackets at trackside.
Mandrel-bent stainless downpipe fabrication for a mid-engine track special in Bristol
Standard mass-produced downpipes forced the exhaust path directly into a transaxle shift cable and scorched the CV joint rubber boot within four laps. The customer brought the vehicle to our shop with melted wiring harness sheathing and carbon soot around the turbo flange. We unbolted the compromised generic pipe and built a fixture from scratch using 3.0-inch 16-gauge T304 stainless steel mandrel bends.
Our master performance parts fabricator machined a custom 1/2-inch thick 304 stainless flange on our mill, radiusing the collector entry to match the turbine discharge bore. We incorporated an interlocking double-braid flex section to isolate engine torque roll from the rear muffler hanger brackets, welded twin wideband O2 sensor bungs at 45-degree upright angles to prevent condensation fouling, and back-purged every joint with 99.99% pure argon. The completed downpipe delivered an extra 42 mm of clearance around the steering shaft and cables.
“Fitment in Wareham is measured against real chassis pickup points, not extrapolated CAD models.”
High-pressure bench pressure testing and shaft runout verification on a competition turbo unit
A high-flow twin-scroll turbocharger was submitted following an unverified rebuild by an online seller. The unit exhibited faint scoring along the compressor cover and excessive end-float play under cold feeler gauges. We mounted the assembly to our Wareham oil-pressure test station, pre-heating synthetic lubrication oil to 180 degrees Fahrenheit at 55 psi line pressure to replicate track-day operating temperature.
Dial indicators confirmed 0.048 mm of radial shaft runout under pressure, exceeding safe limits by 0.023 mm. We replaced the journal bearings with our precision dual-ceramic ball bearing cartridge, fitted high-temperature Viton O-ring seals, and precision-balanced the Inconel 718 turbine shaft assembly to under 0.005 gram-inches across 120,000 RPM simulation. We refuse to release any forced-induction component without a verified zero-leak pressure log.
Five engineering steps taken from raw inquiry to final dispatch
Every order follows a strict engineering verification protocol. We do not grab boxed assemblies off warehouse shelving without checking your chassis dimensions.
Chassis Dimension & Clearance Cross-Check
We evaluate your vehicle make, engine block deck height, steering column angle, and suspension pickup geometry. We cross-reference our database of physical sports car jigs in Wareham to verify that part lines clear headers, anti-roll bars, and brake line brackets.
CNC Flange Facing & Mandrel Tube Cut
Flanges are faced on our machine mill to 0.02 mm surface flatness to eliminate exhaust blow-by. Tubing is cold-cut on a precision horizontal bandsaw, deburred by hand, and acetone-washed before entering the welding fixture.
Argon Purging & Thermal Control
T304 and 4130 chromoly joints are welded using high-purity argon shielding with continuous interior back-purging. This stops sugaring and oxidation inside the pipe, ensuring maximum exhaust gas velocity without turbulence.
Hydrostatic & Pneumatic Bench Test
Turbo housings and intake airboxes are pressurized to 45 psi pneumatic hold. Oil circuits are tested hot at 55 psi with synthetic fluid to confirm 100% seal integrity on all Viton fluorocarbon O-rings.
Inspection Sheet & Hardware Boxing
Completed assemblies receive a serialized inspection tag stamped with measured runout, torque specifications, and hardware packing lists. Shipments dispatch from 9 Tow Rd in Wareham with complete builder guides.
Clear breakdown between component supply and shop bench installation quotes
Factorys Five operates as an independent parts manufacturer and technical machine facility. To maintain absolute transparency for our customers and comply with ad platform standards, we maintain a strict boundary between parts retail pricing and optional installation labor.
Parts Supply: Components are sold individually or as packaged conversion assemblies between $5.99 and $629.99 USD. When you order a downpipe, turbo assembly, or control arm kit, your quote covers the physical hardware, fasteners, gaskets, and engineering documentation.
Separate Installation Labor: If you bring your vehicle or subframe to our Wareham shop for physical fitting, alignment, or dyno test setup, that work is estimated and billed as a completely separate line item. Installation fees depend on chassis rust condition, previous modifications, wiring complexity, and custom bracket adjustments. We never bundle hidden labor costs into our part prices.
Online and telephone quotes for performance parts reflect component purchase prices only. Customers requesting in-facility installation in Wareham, MA will receive a distinct written estimate detailing labor hours, shop consumables, and specialized chassis alignment before any vehicle work begins.
What our components are designed for and who this shop is not suited for
Our performance parts and kits are engineered specifically for track vehicles, high-output sports cars, and serious custom builds. They are not intended for budget commuter replacements or uncalibrated factory engines.
- Not for universal fitment seekers: We do not make one-size-fits-all adapters. If your engine mount is not within our verified blueprints, we will not sell you a bracket that requires hammer clearance.
- Rigid polyurethane and spherical bearings: Our suspension arms use Teflon-lined FK rod ends. They deliver zero deflection on track but transmit road harshness that ordinary commuter drivers will find noisy.
- ECU tuning required: Installing our twin-scroll turbochargers or 3.0-inch downpipes requires custom engine management calibration. Running high-flow induction without fuel re-mapping will cause lean engine damage.
- Inquiry-only pricing: Because race engine tolerances vary by cylinder head casting and manifold choice, we do not operate an instant automated checkout. We verify fitment first.
Manufacturing defect warranty and materials integrity guarantee
Every performance component machined and welded by Factorys Five is backed by our 12-month structural integrity guarantee against weld fracturing, material fatigue, and flange warping under proper competition installation.
This warranty covers defects in 304 stainless steel, 4130 chromoly tubing, and 6061-T6 aluminum machining. It excludes damages resulting from lean AFR fuel detonation, foreign object ingestion into compressor wheels, improper oil pressure supply, or unauthorized field modifications. To initiate a warranty inspection, contact our Wareham shop with your original invoice receipt and digital photos of the installed clearance.
