How It Works

01 / FIND

Browse Curated Listings

We source from Facebook Marketplace, Instagram, BimmerPost, and direct seller submissions. Every listing arrives with verified specs, real photos, and a fitment summary.

02 / VERIFY

Run The Fitment Check

The check runs in your browser. It compares bolt pattern, hub bore, brake clearance, and width/offset with OEM numbers for that chassis. It is a mechanical estimate, not a guarantee — confirm on the car.

03 / CONNECT

Talk To The Seller

We tag sellers in every post and link directly to their listings. No middleman fees, no hidden commissions. Just a clean introduction between buyer and seller.

— THE FOUNDER —

Built By An Enthusiast.
Powered By AI.

MSpec Wheels exists because Facebook Marketplace is broken for BMW wheel buyers. Listings lack specs. Sellers don't respond. Buyers can't tell whether a 19×10 ET20 will fit their G80 without spending an hour on BimmerPost.

We built a tool that answers the question in seconds — and a curated feed that surfaces only the wheels worth your time. No commissions. No middleman fees. Just a free service for the community we belong to.

FAQ

Is the fitment tool actually free? ↓

Yes. Forever. No login required, no email gate, no credit card. Buy us a coffee on Instagram if you want.

Do you take a commission on sales? ↓

No. Sellers keep 100%. We tag the seller in every post and the buyer contacts them directly.

What chassis do you cover? ↓

Every BMW M generation is in the fitment checker now, from the E26 M1 and E30 M3 through current M2, M3, M4, M5, and M8, including Touring, Z3 M, Z4 M, the 1M, M-SUVs, and the XM.

How accurate is the fitment check? ↓

It is a mechanical estimate from the chassis data: bolt pattern, center bore, brake diameter, and width/offset versus OEM. It is not a guarantee. Always test-fit before final mounting; tire brand, camber, and ride height move the result.

Can I sell wheels here that aren't BMW? ↓

Right now we're BMW M only — that's the niche. If we expand, you'll hear about it on @mspecwheels first.
