Asetek La Prima GT (GT Button Box + Round Comfort+ Rim) review: 84 inputs on a swappable round rim
84 mappable inputs sit on this wheel, including magnetic shift paddles and two magnetic clutch paddles for bite-point launches, for ~$415 once you add the round rim to the button box. The La Prima GT Button Box is the control deck and the Round Comfort+ Rim is the grip, sold as separate parts that bolt together on a metal spider. It’s the affordable, modular round-rim option inside the Asetek ecosystem, and the suede stays grippy across a three-hour stint.

Who it’s for
Section titled “Who it’s for”An Asetek base owner who wants one round rim that covers road, GT, rally, and drift without paying flagship money.
Buy it if:
- You’re on an Asetek La Prima, Forte, or Invicta base and want a wheel that just clicks onto the QR.
- You want real input density: 84 mappable controls, funky switches, twelve-position rotaries, and dual clutches for launches.
- You value modularity. The round rim pops off the spider so you can move to a formula, GT, leather, or 340mm dished rim later.
Not the one if you’re not on an Asetek base (a MOZA ESX suits MOZA owners) or you want a dash screen built in (look at a MOZA GS V2P).
Build and feel
Section titled “Build and feel”Stiff composite chassis. The GT Button Box is an injection-molded carbon, glass, and plastic composite shell with a brushed aluminum-look faceplate, sitting over a metal spider mounting interface. The spider is what keeps it from flexing under hard inputs, and it’s also the bolt pattern the rim attaches to, so swapping rims is a few screws rather than a new wheel.
Grippy Comfort+ suede. The 330mm round rim wraps in Asetek’s Comfort+ suede-style microfiber: 37% recycled fibers, permanently fire-resistant, antistatic, and rated to 150,000 Martindale rubs. Black hand-sewn stitching runs the grips and a red marker sits at center so you can find straight-ahead by feel. The suede grips dry or sweaty hands without the slick spots cheaper PU rims get.
Magnetic paddles, dual clutches. Behind the rim are magnetic shift paddles and two magnetic, non-contact clutch paddles for dual-clutch bite-point starts. Non-contact magnets mean no microswitch to wear out and a consistent actuation point. All 84 inputs bind in Asetek RaceHub, where you also set the rev light range and clutch bite percentage.
Watch-outs
Section titled “Watch-outs”- No display. You get a 15-LED RevLED strip and nothing else, so fuel, deltas, and tire temps come from an in-game or overlay dash. Fine if you already run one, a gap if you wanted a glance-down screen.
- Asetek-only ecosystem. Power and data pass through the Asetek QR on Asetek bases. There’s no cross-brand adapter and no standalone USB mode, so the wheel is worth nothing without an Asetek base under it.
- Rim sold separately. The Round Comfort+ Rim is a different SKU from the GT Button Box. The ~$280 button box is only the control deck; budget the ~$135 rim into the real price.
Alternatives to consider
Section titled “Alternatives to consider”- Simagic GT Neo: GT-shaped rim for Simagic bases at ~$289, if you want a flat-top D-shape and live in the Simagic ecosystem.
- MOZA GS V2P GT Wheel: ~$369 GT wheel for MOZA bases with a built-in display, the screen the La Prima leaves out.
- MOZA ESX: ~$129 round wheel for MOZA bases if you want round-rim feel at the entry price rather than mid-range input density.
- Fanatec ClubSport Universal Hub V2: ~$370 universal hub if you want to mount your own aftermarket rim and aren’t locked to one brand’s quick release.
Once the wheel’s on the QR, open RaceHub and map the funky switches and clutch bite point before your first race. The button mapping guide covers what to bind first.
Frequently asked questions
Does the Asetek La Prima wheel need its own base?
Yes. It mounts on the Asetek quick release and pulls power and data through it, so it works only on Asetek direct-drive bases: La Prima, Forte, and Invicta. There is no cross-brand adapter and no standalone USB mode. If you're not in the Asetek ecosystem, look at a MOZA ESX or Simagic GT Neo instead.
Is the rim included with the GT Button Box?
No. They are two separate SKUs. The La Prima GT Button Box is ~$280 and the Round Comfort+ Rim is ~$135, so the combined wheel is ~$415. The round rim bolts onto the button box's metal spider and swaps for Asetek's formula, GT, leather, or 340mm dished suede rims.
Does it have a dash screen?
No LCD or dash screen. You get a single strip of 15 aRGB RevLEDs for rev and shift lights, customizable in Asetek RaceHub. Telemetry like fuel, lap delta, and tire temps relies on an in-game or overlay dash.
Asetek La Prima wheel or Simagic GT Neo?
Different ecosystems. The La Prima wheel only runs on Asetek bases and gives you 84 inputs plus dual magnetic clutches for ~$415 combined. The Simagic GT Neo is a GT-shaped rim for Simagic bases at ~$289. Pick by the base you own.
