How do you track car mods properly? (Build log guide)

A practical build log system for tracking car mods, costs, and decisions—mapped to the Drivurs digital garage fields.

Drivurs Team

TL;DR

Track each mod with five essentials: what, why, cost, result, and one short detail for future-you. Keep vehicle photos up to date, and when you change parts, record the change so you don’t lose recall later.

In Drivurs today, you can track mod name/brand/category/cost, optional HP/torque gains, and quick ratings—plus a vehicle photo gallery. Drivurs does not provide a dedicated “removed parts” history view yet.

Why most build logs fail

Build logs don’t fail because you’re lazy—they fail because the system is too hard to maintain.

Common failure modes:

  • Tracking requires “desktop time” instead of quick updates on your phone
  • Entries are unstructured (“Installed turbo kit lol”) and impossible to search later
  • Costs live in receipts/screenshots, not in the build history
  • You remove a part and erase the context that would help you troubleshoot later

The build log fields that matter

If you’re tracking mods, start with these fields:

  1. Name (the part or change)
  2. Category (engine, suspension, brakes, etc.)
  3. Brand (optional but useful later)
  4. Cost (even if approximate)
  5. Result (what changed—feel, reliability, data, or just “fixed the issue”)

Optional but helpful:

  • Difficulty (1–5)
  • Satisfaction (1–5)
  • Estimated gains (only if you have real data)

Start with a baseline (so comparisons mean something)

Before you add the first mod, write down a baseline:

  • Stock horsepower (or your last known dyno number)
  • Current mileage
  • Current tire/wheel setup
  • Any existing issues (“boost leak at high load,” “brake fade after 3 pulls,” etc.)

This isn’t about being scientific—it’s about giving future-you context. Without a baseline, every mod feels like “it made it faster” even when it didn’t.

Drivurs garage tracking (what it supports)

Drivurs is designed so you can track mods without reinventing a spreadsheet:

  • Mod name, brand, category, and cost
  • Optional horsepower/torque gains
  • Install difficulty and satisfaction
  • Vehicle photos (gallery) and a clean garage overview

If you want the full feature overview, start at Digital Garage.

Step-by-step: track mods in Drivurs

  1. Add your vehicle
    • Add year/make/model and baseline info.
  2. Add a modification
    • Pick a category so it stays organized.
    • Add cost (even approximate) and any optional gains/ratings you know.
  3. Update as the build evolves
    • Update your mods so the garage matches what’s installed today.
    • If you care about a full change history, keep a lightweight log for now (until Drivurs adds a dedicated history view).
  4. Keep vehicle photos current
    • A clean hero photo makes your garage easier to recognize at a glance.

Track changes over time (without a dedicated history view yet)

Real builds aren’t linear. You swap parts, revert changes, and iterate.

If you want “why/result” context and a real revision history, you need a place to store it. Today, Drivurs is optimized for tracking your current mod list (plus cost/gains/ratings).

Until Drivurs ships a dedicated history view, use a simple external log:

  • One note per change (date + “replaced X with Y” + 1–2 bullets on why/result)
  • Keep it linkable/shareable (Notes app, Notion, Google Doc, etc.)
  • Treat Drivurs as the authoritative “what’s installed now”

Power vs reliability (write the tradeoff down)

Some mods are pure performance. Others are reliability, drivability, or safety.

When you log a mod, capture the tradeoff somewhere:

  • “This is for power.”
  • “This is for reliability.”
  • “This is for safety.”
  • “This is for drivability/comfort.”

This keeps your build honest and makes future planning easier. It also helps you explain the build to a new owner or to a shop/tuner.

Maintenance counts (log it like a mod)

Oil changes, brake fluid, tires, alignment—these are part of the build.

If you want a garage log that stays useful, log maintenance with the same structure:

  • What
  • Why
  • Cost
  • Result
  • One detail for future-you

“Maintenance” is often the reason a car feels good. Don’t let it vanish from your history.

Photo strategy (so the build story is clear)

Three photo habits make a build log dramatically better:

  1. A “current state” hero photo every few months
  2. One photo per major install (before/after)
  3. A photo of any problem area you fixed (so you remember what it looked like)

The point isn’t aesthetics—it’s recall.

Common mistakes (why mod tracking goes stale)

  • Not updating your current mod list after swaps (the garage becomes fiction)
  • Logging “gains” without a repeatable baseline (placebo math)
  • Dumping everything into “Other” instead of using categories
  • Tracking cost but not tracking satisfaction/difficulty (you repeat painful installs)
  • Assuming the app will preserve removed-part history automatically (use an external log for now)

Template: a perfect mod entry (copy/paste)

  • Mod: [Part name]
  • Category: [Engine / Suspension / Brakes / …]
  • Why: [Goal or problem you’re solving]
  • Cost: [$ amount, parts/labor note]
  • Result: [What changed? Any issues?]
  • Would I do it again? [Yes/no and why]

Who this build log system is for (and who it isn’t)

This approach is for you if you:

  • Change parts often and forget what’s installed
  • Want to track costs and decisions over time
  • Care about reliability and repeatability, not just the highlight reel

It’s not for you if you only want a photo album with no tracking.

FAQ

Should I track exact horsepower gains?
Only if you have real data. Otherwise, log the mod and your subjective result, then compare later under similar conditions.

What if I don’t know the exact cost?
Estimate. “~$500” is better than nothing. Add a note if labor was bundled.

How detailed should notes be?
One short detail is enough if it captures the why and the result.
