Purchase Guidance

Buyer's Guides

Buyer guides should help customers choose the right part for the vehicle, budget, use case, and support requirements.

Start With The GoalDaily, drag, drift, track, off-road, show, or mixed-use builds need different compromises.

Pick Your Build Direction

Choose the way the car is used, the main goal, and the budget. The page will point shoppers toward the most useful guide path before they start clicking parts.

Recommended Path Cooling & Reliability

Start with reliability checks, then use calculators and staged shopping to protect the build.

Choose The Right Lane

Each guide should help a shopper understand what the part changes, what it requires, and when a different upgrade makes more sense.

Turbo / Nitrous / Fuel

Power Adders

Forced Induction 0 visual assets

Match horsepower goals with fuel system, cooling, tuning, driveline, and reliability limits.

Best For: Boost, nitrous, or serious naturally aspirated power goals. Avoid If: Maintenance is unknown, fuel system is weak, or tuning is not planned. Support Mods: Injectors, fuel pump, intercooler, plugs, wideband, tune, clutch or converter.

Suspension / Wheels / Tires

Handling Setup

Suspension / Wheels 0 visual assets

Balance stance, grip, clearance, ride quality, and alignment before ordering fitment-sensitive parts.

Best For: Street grip, drift angle, track response, or fitment planning. Avoid If: Wheel specs are guessed or tire diameter has not been checked. Support Mods: Alignment, arms, bushings, tire size, spacers, studs, fender clearance.
Open Guide Path
Street / Track / Drag

Brake Packages

Performance Brakes 0 visual assets

Choose pads, rotors, fluid, lines, cooling, and safety gear around the way the vehicle is used.

Best For: Higher speed, heavier wheels, track days, towing, or repeated hard stops. Avoid If: Only looks matter or tire grip is still the main braking limit. Support Mods: Brake fluid, stainless lines, cooling ducts, bedding procedure, torque checks.

Heat / Oil / Coolant

Cooling & Reliability

Cooling System 0 visual assets

Protect the build with temperature control, fluid capacity, hoses, clamps, and service intervals.

Best For: Boosted cars, track sessions, towing, hot climates, or older builds. Avoid If: The root issue is a leak, bad fan control, or poor maintenance. Support Mods: Radiator, fans, oil cooler, thermostat, hoses, clamps, shrouding, coolant.

Track / Race Use 0 visual assets

Separate daily-driven upgrades from closed-course parts, legality notes, noise, service, and comfort.

Best For: Customers deciding between daily, weekend, track, drag, drift, or off-road use. Avoid If: No clear driving goal, class rule, or road-use requirement has been chosen. Support Mods: Safety, emissions notes, noise, heat shielding, tires, fluids, service intervals.

Install Readiness

Install Support 0 visual assets

Know the required tools, supporting mods, install difficulty, and follow-up checks before checkout.

Best For: First-time installs, weekend projects, and customers buying full packages. Avoid If: A professional shop is required and the customer has not budgeted labor. Support Mods: Tools, fluids, gaskets, hardware, torque notes, post-install inspection.

AI Guide Brief

Describe The Build

This gives shoppers a quick way to frame the decision before they move to the Build Planner or calculators.

Recommended start: Power Adders, Injector Calculator, Turbo Calculator, and AI Build Planner.

Shop By Stage

Stages keep the page from becoming a wall of parts. Customers can pick how serious the build is, then see the support parts that belong with that level.

Stage 1

First Reliable Upgrade

Great for daily and weekend cars: intake, exhaust, tune, tires, pads, fluids, and basic monitoring.

Stage 2

Balanced System

Adds supporting parts so power, handling, braking, cooling, and drivability improve together.

Stage 3

Purpose-Built Package

For serious street, drag, drift, track, or off-road use with safety, service, and class rules considered.

Use The Calculators

Numbers should narrow the decision before checkout, especially when a part changes gearing, tire diameter, fuel demand, turbo sizing, or wheel clearance.

Horsepower Turbo Injector Gear Ratio Tire Size Wheel Offset

Before You Buy

A strong buyer guide slows the customer down just enough to protect their budget, fitment, and install timeline.

  • Vehicle year, make, model, trim, engine, transmission, and drivetrain
  • Current mods, maintenance condition, budget, install skill, and deadline
  • Street legality, emissions limits, track rules, noise, and inspection requirements
  • Supporting mods, tuning, fluids, hardware, tools, and service parts

Turn The Guide Into A Build

Use the AI Build Planner when the customer knows their vehicle, goal, use case, and budget. It can turn guide choices into a staged parts path.

Plan A Build

What should I know before buying performance parts?

Start with vehicle fitment, use case, budget, current maintenance, support mods, legality, and install difficulty.

Should I buy one part or a full stage package?

A stage package is safer when the upgrade needs tuning, fuel, cooling, drivetrain, or safety support to work correctly.

Which calculator should I use first?

Use horsepower for power targets, injector and turbo for forced induction, tire and wheel offset for fitment, and gear ratio for driveline planning.
