The data behind the drive.
Independent buyer guides for sim racers — direct-drive wheelbases, wheels and rims, load-cell pedals and cockpits, compared on the numbers that actually decide the buy: torque (Nm), drive type, ecosystem and fit. Plus a torque matcher and a rig-fit calculator that tell you the Nm band and the rig that suit you — before you spend. Written by a sim racer who bought the wrong first wheel so you don't have to.

Choose your path
Three doors. Where you start depends on whether you are still deciding, want a Nm-and-ecosystem recommendation, or just need to know it will fit your desk.
I'm choosing my first wheelbase
Read the beginner guide. Why torque (Nm) and drive type matter more than buttons, direct-drive vs belt vs gear in plain English, the Nm tiers, and the ecosystem trap that costs you twice.
Open →I want the right Nm and ecosystem
Use the Direct-Drive Torque Matcher. Tell it desk vs rig, your discipline (GT / rally / F1 / oval) and budget, and it returns a recommended Nm band, ecosystem fit and a shortlist.
Open →I want to know if the rig fits me
Use the Rig-Fit Calculator. Enter your height, seating style and space, and get a recommended cockpit type, seat-to-pedal and wheel-height fitment ranges, occupant-fit flags and a footprint estimate.

Wheelbases
Direct-drive vs belt vs gear, the Nm torque tiers (entry 5–8 / mid 8–12 / high 18+), and the ecosystem lock-in trap — Fanatec, Moza, Logitech and Thrustmaster compared by the numbers.
View guides →Wheels & Rims
GT vs formula vs rally rims, button-box and display, and quick-release (QR) compatibility — which rim mounts which base, so you do not buy a wheel your base cannot take.
View guides →Pedals
Load-cell vs potentiometer, 2 vs 3 pedal, brake-force (kg) tuning and hydraulic — why the pedals fix your braking before a new wheelbase ever will.
View guides →Cockpits & Accessories
Foldable cockpit vs aluminium-profile chassis vs wheel stand, plus shifters, handbrakes and mounts — rigidity vs desk space, and where everything bolts on.

Best sim racing wheelbases
Direct-drive wheelbases compared by Nm tier, drive type and ecosystem — the cleanest path to a base you buy once.
Best sim racing wheels & rims
GT, formula and rally rims compared on diameter, material, buttons, display and QR fit — and which base each one mounts to.
Best sim racing pedals
Load-cell and hydraulic pedal sets compared on pedal count, load-cell force, travel and mount — the upgrade that fixes braking first.
Best sim racing cockpits & stands
Foldable cockpits, aluminium-profile chassis and wheel stands compared on type, rigidity, fit and weight.

Who writes here
Direct Drive Data is founded and written by Marco Delgado, a sim racer in Austin, Texas who races iRacing and ACC on his own direct-drive rig. He started the site after wasting money on the cheapest gear-driven wheel he could find — it clipped, felt mushy, and nearly made him quit before a league mate's direct-drive rig changed his mind. Some articles also come from rotating contributors — league teammates and longtime rig builders. Product comparisons stay neutral and spec-led — no fabricated hands-on testing.
