Asetek La Prima GT (GT Button Box + Round Comfort+ Rim) review: 84 inputs on a swappable round rim

Asetek claims 84 mappable inputs on this wheel, and it sells you the inputs and the thing you hold as two SKUs: a $259.00 La Prima GT Button Box and a $149.00 Round Comfort+ Rim, $408.00 for the pair. Its own listing prints “Note: Rims are sold separately”. The button box is the control deck and the rim is the grip, bolting together on a metal spider. Swap the Comfort+ for the cheapest $109.00 rim and the pair is $368.00, which is the least Asetek charges for any box-and-grip combination it sells, $10.00 under the formula equivalent of a $289.00 La Prima Formula Button Box plus $89.00 Regular Handles. It is not the cheapest Asetek wheel: the $149.00 Initium Steering Wheel and the $349.00 La Prima Formula Steering Wheel both arrive complete. The microfiber grip carries a 150,000 Martindale abrasion rating.

Type	Round sim-racing wheel (GT Button Box + Round Comfort+ Rim, separate parts)
Rim	Comfort+ suede-style microfiber (37% recycled fibers, fire-resistant, antistatic, 150,000 Martindale), hand-sewn stitching, red center marker. Asetek gives its box list as "Rim 12.9 in" and the box's own size as "330 mm diameter with rim"
Inputs	84 claimed. The specification lists 8 push buttons, 2 seven-way kinky switches, 3 twelve-position rotaries, 2 thumb encoders, and 2 contactless magnetic shifter paddles, which is 17 physical controls
Display	None. 15 aRGB RevLED strip only; no LCD or dash screen
Connectivity	Asetek quick release (power + data through the QR); "All Asetek Racing™ Wheelbases". The only two occurrences of USB on the listing are a navigation thumbnail's alt text, so no port of its own. Other brands' bases go through Asetek's $129.00 3rd party wheelbase QR Adapter, which this listing does not name
Price	$408.00 combined (Button Box $259.00 + Round Comfort+ Rim $149.00); rim sold separately, and the cheapest rim makes it $368.00
Best for	Asetek base owners wanting an affordable, modular round rim

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 base and want a wheel that just clicks onto the QR. Asetek’s compatibility row names all of its wheelbases and no one else’s.
• You want input density at the price: 84 claimed mappings across 8 push buttons, 2 seven-way kinky switches, 3 twelve-position rotaries, and 2 thumb encoders.
• You value modularity. The rim pops off the spider, and Asetek sells six others it fits: black or orange leather in closed-D, black leather or black suede in open-D, black leather in round, and a 340 mm dished suede.

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

Stiff composite chassis. The GT Button Box is an injection-molded carbon, glass, and plastic composite shell with an aluminum face plate, sitting over a metal spider mounting interface. Asetek’s own phrase for what that buys is “a stiff, non-flexing wheel”. The spider is also the bolt pattern the rim attaches to, so swapping rims is a few screws rather than a new wheel, and the box ships with none fitted.

Grippy Comfort+ suede. The 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. Microfiber is a napped fabric, so the grip comes off fiber against skin, where a cheaper molded PU rim gives you a smooth surface to hold. Asetek measures the rim itself at 12.9 inches and the box fitted with a rim at 330 mm, and never says which rim the 330 mm was taken with.

Two magnetic paddles, and no clutch in the box. Behind the rim sit two contactless magnetic shifter paddles. Non-contact magnets mean no microswitch to wear out and a consistent actuation point. That is the whole paddle count Asetek publishes, and its Inputs & Controls table agrees at 2. Clutch paddles are one of three paddle accessories sold separately for this box, beside Magnetic Input Paddles and a Carbon Paddles Kit, so bite-point launches are a purchase rather than a feature here. The 84 mappings bind in Asetek RaceHub, whose four listed features on this product are button mapping, customizable rev lights, pitlane control and pit limiter, and night mode.

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 quick release, and the adapter isn’t on this page. Power and data pass through the Asetek QR, and this listing’s compatibility row names its own wheelbases and nothing else. The word USB appears twice on the page and both are a navigation thumbnail’s alt text, so there’s no standalone mode. What gets the box onto another brand’s base is a $129.00 3rd party wheelbase QR Adapter in Asetek’s Accessories category, which this listing never mentions: its own page claims “cross compatibility between all Asetek Racing™ steering wheels and more or less all other brands of wheelbases”. So the box is not stranded off an Asetek base, it just costs $129.00 more to leave, and you’ll find that out somewhere other than here.
• Rim sold separately. The Round Comfort+ Rim is a different SKU from the GT Button Box, and Asetek prints “Note: Rims are sold separately” above the cart control. The $259.00 button box is only the control deck; budget the $149.00 rim into the real price, or $109.00 if you take the cheapest one.
• The orange one is out of stock. Asetek sells this box in two colorways at the same $259.00, and on 4 August 2026 the orange listing read “Out of stock.” with no cart control while the black one read “In stock and ready to ship”. Asetek doesn’t say the orange is going away, and a sold-out page isn’t proof of it, but the orange is the older of the two on Asetek’s own photography dates.

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: $399 GT wheel for MOZA bases, carbon and leather where the La Prima is a button box and a separate rim.
• MOZA ESX: $139 round wheel for MOZA bases if you want round-rim feel at the entry price rather than mid-range input density. That is one price for a working wheel against $368.00 for the cheapest box-and-rim pair here.
• Fanatec ClubSport Universal Hub V2: ~$370 universal hub if you want to mount your own aftermarket rim and the base under it is a Fanatec. Universal describes the rim side, a published 6x70mm and 3x50mm pattern; the base side is QR2 and Fanatec only.

Once the wheel’s on the QR, open RaceHub and map the kinky switches and the rev light range before your first race. The button mapping guide covers what to bind first.
