Car Mods Catalog — Reviews, Fitment, Where to Buy

The SPOOLED mods catalog: aftermarket parts with brand, category and vehicle fitment data, plus owner reviews where owners have written them.

Last updated 2026-07-21·Open Mods

The SPOOLED mods catalog is the single index of every aftermarket part we track — turbo kits, exhaust systems, suspension components, wheels, tunes, intercoolers, and every other category an enthusiast might shop for. Every entry carries the same set of evidence: how many real owners have it installed, what they think of it, and which other mods they paired it with.

What you can find on /mods

  • Installs — every mod page lists the builds it's fitted to. Click through to see the rest of those builds' mod lists and photos.
  • Fitment data — which year/make/model combinations the part is confirmed to fit.
  • Paired mods — other parts in the same category that owners of this one also run, ranked by how often the two appear on the same build. Useful for seeing what people upgraded to or ran instead.

Filters that actually work

The catalog filters by category, vehicle fitment (year / make / model / trim), and OEM+ status, plus a free-text search across part name, brand, and part number. You can then sort the results by install count, rating, review count, or newest. One combination in particular is worth calling out:

Category × fitment. Pick a category like turbo, then filter to your exact car. You get every turbo we track that's confirmed to fit a 2018 Civic Si, ranked by install count. This is the closest thing to "best mods for my car" without sponsored placements pretending to be recommendations.

The full taxonomy — 22 categories — is: engine, boost, intake, exhaust, ecu, fuel, cooling, fluids, drivetrain, suspension, chassis, brakes, wheels, tires, exterior, interior, lighting, audio, aero, safety, accessories, other. New categories get added as the catalog grows; if a part doesn't fit any of these it lands in other.

From "best mods for my car" to a working list

The most common way to use the catalog: open /mods, filter to your car, sort by install count, and read down the list. For each mod you're considering, click into the page and check:

  1. Star rating and review count — a 4.9 with 3 reviews is not the same data point as a 4.6 with 87.
  2. The paired mods section — other parts in the same category that owners of this one also run, ranked by how often the two appear on the same build.
  3. Linked how-to guides — install difficulty and time, in the words of someone who actually did it.
  4. The installs tab — open one or two builds with similar goals to yours and see what their full mod list looks like.

That four-step pass beats a generic "best mods for [car]" search every time, because every signal you're reading is tied to a real car you can click through to. Combine the catalog with the shop directory and the tuner directory and you have an end-to-end answer to what to buy, who to install it, and who to tune it.

Frequently asked

Are the buy links sponsored?
The buy links on mod pages and in our guides are platform-affiliate links — clicks support SPOOLED at no cost to you. We don't take payment to rank one mod above another, and ranking is driven by install count and rating, not commercial relationships. When a creator on the platform attaches their own affiliate link to a build or how-to, that link is theirs and the commission is split with them; the editorial guide links are platform-only.
Can I trust reviews if owners have an incentive to inflate ratings?
In the SPOOLED mobile app, readers can mark a review helpful, and the author earns PSI for it — PSI rewards helpful reviews, not high-rated ones, so there's no incentive to inflate. Reviews shorter than 30 characters earn a reduced PSI award, so low-effort reviews carry less weight in the contribution score.
How is "best mod for my car" decided?
There is no algorithmic "best." Filter to your car and the catalog shows every part confirmed to fit it, ranked by how many SPOOLED builds have that part installed, with rating as a tiebreaker. That's materially different from a sponsored top-10 list.
