Mazda NB Miata Track Build

Overview

This is an ongoing project focused on converting a 1999 Mazda NB Miata into a track monster. It's been heavily modified so far, and I continue to make heavy changes to the car's layout and chassis. This page, for now, will stand as a list of current upgrades and modifications. Once the build slows down or comes to an end, I'll write a full project post with details.

Objective

The objective with this project is to build a track capable monster, all while deep diving into race car technology, how it works, and why it's important. This car represents my intro to automotive systems.

Upgrades

So far, I've made the following modifications:

Interior:


• NRG Steering Wheel Quick Release: For quick removal of the steering wheel, in case of emergencies
• Sparco R345 250mm Suede Racing Wheel: For better hand-wheel interface, and lack of airbag (unnecessary with proper seats & harnesses)
• PCI Innovations Side Mount Seat Mount (x2): Miata specific mounts for sparco bucket seats
• Sparco EVO QRT Bucket Seat (x2): For maximum comfort and lateral support when driving
• BRAUM 5-Point Racing Harness (x2): For increased safety and to follow track rules
• Bluetooth Receiver Board: So I can play music through my phone on the stock head unit
• Blackbird Fabworx GT3 Style NB Rollbar: For rollover protection and to follow track rules
• Flyin' Miata Reinforced Door Bushings: For increased chassis stiffness

Engine:


• AEM Cold Air Intake: For increased engine performance and improved acoustics
• Mishimoto Performance Radiator: For lower operating temperatures
• Megan racing Hi-Flow Muffler: For improved acoustics and exhaust flow

Driveline:


• Racing Beat NB Tubular SwayBar: For reduced body roll to improve handling
• Ohlins DFV Road and Track Coilovers: For improved handling and superior adjustability
• Hawk DTC-30 Racing PadsFor improved high-heat and initial bite break characteristics
• Wildwood Brake Proportioning ValveAllows for brake bias adjustment for better braking balance
• Advanti Storm S1 15x8": For reduced unsprung weight and improved looks
• Bridgestone Potenza RE-71RS 205/50/R15: For better driving grip

Exterior:


• Duraflex NB Style Front BumperFor post deer-incident repairs
• Unbranded Tow Hook: For easier towing in case of emergencies
• Leroy Engineering NB Side Skirts: For slight downforce and improved looks
• 3M 2080 Purple Fuchsia Vinyl Wrap: For improved aesthetics

What I'm Learning

• How suspension component adjustment changes drivability through camber, caster, toe, etc.
• How aerodynamic components improve vehicle performance
• How to perform basic and advanced service on a Miata
• Track day setup and troubleshooting
