Comparison
WySync Fitment vs Convermax
Convermax is the incumbent in aftermarket fitment search — for wheels, brakes, suspension, lighting, every category — and they're good at it. This page is the honest version of the comparison: where we're cheaper, where we're fresher, where we ship something they don't, and where they're the safer choice.

We can sell you the data
Convermax indexes the fitment you already have. So do we — for every category. But for wheels and tires specifically we can also rent you ours: the $150/mo add-on judges specs directly, so a gappy supplier feed stops being your problem.
Pro + Data = $699 — Rim Mastery's exact sticker, with the data included.
The index is fresher
Their indexing runs as a 12-hour batch on every plan. Our cheapest plan reindexes every six hours; from $299 we subscribe to product, inventory and price webhooks so a price change or a sell-out reaches the storefront in seconds, with a daily full reindex behind it as a safety net.
We guard the cart
Fitment that only runs on the product page still lets a bad set reach checkout — a shopper switches vehicles, or adds from a saved link. We re-verify every cart line against the active vehicle and can hard-gate the checkout button until it's resolved.
- You need VIN decoding today. Their Stage 3 plan ships VIN search. Ours doesn't yet.
- You want the AutoSync visualiser. Rim Mastery bundles a wheel-on-car visualiser and DriveRightData. We don't render parts onto a photo of the shopper's vehicle.
- You're not on Shopify. They support several platforms; we are Shopify-only and won't pretend otherwise.
- You want the incumbent. They have been doing this longer and have more stores live. That is a real reason, and we'd rather you weigh it honestly than find out later.

You don't have to rebuild your fitment to try us.
The migration switcher runs on your live storefront while Convermax is still installed. It reads the fitment they have already resolved for each product — including anything you corrected inside their editor — and captures it as a WySync source. You compare the two side by side, and only then cancel.
- Install alongside
No theme changes yet. The app indexes your catalog in the background.
- Capture
The switcher records their resolved fitment per SKU as you browse, plus native tags and metafields.
- Reconcile
The admin shows what matched, what only they had, and what only we found.
- Cut over
Swap the theme blocks, verify on your top ten SKUs, then cancel the other subscription.
Run both for a month. Keep the one that sells more.
Our trial is thirty days and migration is free, so the comparison costs you nothing but the theme editor time.
