MC Racing

Race vehicle preparation and trackside engineering.

Workshop: 370 Hudson Rd, Stow, MA
Inquiry Phone: 978-562-9400
Program Fleet: 1 to 10 Competition Cars

MC Racing offers race vehicle preparation, telemetry data acquisition, and trackside engineering from our Stow, Massachusetts facility. Every mechanical service is executed to sanctioning body compliance for SCCA, NASA, and PCA club racing.

Every project is quoted individually, strictly depending on five real variables:

  • Event type: test day, sprint weekend, endurance championship, or arrive-and-drive track day.
  • Program duration: single track session, two-day weekend, or full multi-round season support.
  • Number of cars: from single privateer entries up to 10-car team programs.
  • Level of preparation: baseline mechanical safety inspection up to ground-up corner balancing and custom telemetry harnesses.
  • Logistics and support: trailer transport distance from Stow, fuel allotments, tire warmers, and paddock pit footprints.

Lead time is provided on inquiry. Below is our four-point technical preparation catalogue with full engineering specifications and price bases.

Chassis Corner Balancing & Alignment

Individual wheel corner balancing is calibrated using digital scale pads to achieve a 50.0% cross-weight balance (±0.5 kg). We set negative camber, caster angle, and laser hub toe-in tailored specifically to the asphalt friction coefficient and high-load banking of your destination circuit.

Damper ride height collars are indexed with micrometers under full race trim, including driver-equivalent seat ballast and indexed fuel cell load. We prevent bump-steer geometry bind throughout the full stroke of the suspension uprights.

Cross-Weight Tolerance
±0.5 kg across diagonals
Measurement Tools
Intercomp digital scales, laser hub fixtures
Target Applications
GT, Touring Car, Spec Miata, Formula
Ballast Protocol

Telemetry Harness & Sensor Integration

High-speed CAN bus logging systems utilizing AiM and MoTeC hardware architectures are wired and programmed in-house. Linear suspension potentiometers are fitted at all four corners to map damper velocity histograms, bump-stop compression, and chassis pitch during heavy trail braking.

Four-channel infrared tire temperature arrays monitor inner, center, and outer tread thermal build across long stints. We configure steering angle sensors, throttle position inputs, brake line hydraulic pressure transducers, and GPS lap timing into a unified digital cockpit dashboard.

Trackside Pit Crew & Paddock Support

Our trackside engineering crew deploys direct to regional circuits to support between 1 and 10 vehicles. Led by Ivan Petrov, team mechanic since 2018, the pit crew handles tire pyrometer checks immediately as the car enters pit lane, calculating cold-to-hot pressure delta bleeds to hit target working grip.

Mobile nitrogen inflators, tire warmers, refuel rigs, brake caliper temperature thermal paint logging, and rapid paddock repair diagnostics are staged at every event. After each session, run sheets are recorded and debriefed before the subsequent run group.

Fleet Support Window
1 to 10 vehicles managed simultaneously
Paddock Tooling

Brake System Overhaul & Bedding

Brake failure on circuit is catastrophic. We rebuild AP Racing, Brembo, and PFC racing calipers with high-temperature silicone piston boot seals and stainless steel fluid crossover bridges. Every brake rotor is dial-indicator measured for axial runout down to a maximum allowable tolerance of 0.02 mm before installation.

All mounting hats are fastened with grade 10.9 or titanium hardware and secured with stainless steel safety-wire. Hydraulic lines are high-pressure vacuum flushed with Motul RBF 660 racing fluid to eliminate microscopic air pockets that cause pedal sponginess under heavy downhill threshold braking.

Runout Ceiling
0.02 mm maximum dial variance
Hydraulic Fluid
Motul RBF 660 (617°F dry boiling point)

MC Racing Technical Inspection Guarantee

Official Workshop Guarantee

Because racing takes place in extreme competition environments beyond workshop control, warranties on circuit machinery differ from consumer retail guarantees. MC Racing guarantees that every vehicle delivered to the paddock complies with the following technical verification standards:

Torque & Fastener Guarantee

Paint-Marked Torque Certification

Every suspension pickup bolt, hub nut, brake caliper mounting bolt, and steering link is torqued to manufacturer specification with calibrated torque wrenches and indexed with high-temp inspection paint. Any fastener defect found prior to wheel-turn is rectified immediately at our expense.

Hydraulic Purity Standard

Zero-Air Brake Fluid Guarantee

Brake lines flushed in our Stow bay carry a verified dry boiling point test and pressure bleed. Should pedal travel deviate from bench specification prior to first session heat-cycling, our team re-bleeds and tests the hydraulic circuits free of charge.

Geometry Fidelity Standard

Setup Sheet Alignment Truth

Corner weights, toe settings, and camber angles recorded on your setup sheet are certified to match scale readouts to within ±0.5 kg cross-weight before trailer transport. Drivers are invited to verify scales on our workshop floor prior to loading.

Sanctioning Tech Pass

Rulebook Compliance Assurance

When contracted for complete prep, we guarantee your vehicle passes technical inspection for the specified sanctioning body (SCCA, NASA, PCA). If a vehicle is rejected for an MC Racing preparation error, our paddock crew remedies the item trackside at no additional labor fee.

Warranty limitations: Does not cover crash damage, driver over-revs, flat-spotted tires, or foreign object road debris. MC Racing Stow MA
