Seemingly since its inception, the wheel spacer has never evolved. For years, we have simply accepted that a spacer should be a round piece of aluminum with five holes punched into it. More than that, we’ve learned to begrudgingly ignore unfavorable wheel vibrations in the name of an aesthetic upgrade. Until now.
Future Classic has taken a brand new approach to the wheel spacer, literally re-engineering the standard for what a spacer should be and with it, our expectations.
For those of you who may be on the fence or simply just like to delve into more technical discussion, we're here to breakdown some of the highlights behind the A90-specific kit and why they're the very best choice for your car. From our product listing:
Future Classic’s quest was simple: to build the best wheel spacer kit at the highest quality standard possible. Partnering with Fall-Line Motorsports to build and test the prototypes in true motorsport conditions has made that dream a reality—the Future Classic wheel spacer is not only a visual treat but a marvel to handle—its machining and finishing work reflects our commitment to detail, every piece of it feels engineered and massaged to the tightest tolerances.
Reason #1: A Comprehensive Approach
To create the most complete wheel spacer kit, Future Classic has painstakingly sourced a complimentary suite of products that are included in every box—four hub bolts, race worthy Copaslip copper anti-seize, an anti-seize applicator brush, and of course, wheel bolt hardware. The hub bolts help ensure you won’t experience the notorious spacer “wobble” from improper installation / uneven seating on the hub surface. Copaslip is the definitive motorsport anti-seize assembly compound. It is trusted by professional racing teams the world over for its incredible working temperature range (-40°C to 1100°C).
Reason #2: Engineered Design and Machining
The Future Classic wheel spacer is a far step beyond your conventional kit. Whereas most kits just look like a sliced section of cylindrical aluminum with some holes punched into it, the Future Classic variant has literally been engineered to perform. Premium 6061-T6 aerospace aluminum provides the foundation from which the spacer takes shape. Once complete, the spacer’s machine work is evident to even the untrained eye—flawless surface finishing, impossibly tight tolerances, and a balanced, symmetrical shape all become immediately apparent.
Aside from the lug bolt holes, two slotted hub bolt partitions exist to account for the different front and rear bolt positions—on the A90 Supra (much like the non-M BMW lineup), you will make use of two hub bolts per axle—so you will have two spares. With careful calculation, additional pocketing has been machined from the spacer to shave unnecessary weight without strength loss penalty. Chamfered edges adorn the rear of the spacer surface as an extra precautionary measure in rare cases where removal proves finicky.
Although an almost immeasurable detail, the real ace in the back pocket comes from a subtle, but substantial hubcentric reinforcement. Without this extra step, conventional spacers often shear from this hubcentric ring. In some cases, the ring becomes an inconvenient procedure to remove from the wheel. In others, spacer failure can cause the car’s occupants to sustain serious injury. Future Classic’s strengthening helps safeguard against these dire circumstances.
Each Future Classic spacer is black anodized to perfection in order to ward off corrosion and wear resistance. As a finishing touch, the spacer size and specification are legibly lasered onto the surface.
Reason #3: Motorsport Tested
As a direct benefit from working alongside Fall-Line Motorsport in engineering this kit, the spacers have been rigorously tested in true race conditions. The production pieces are the result of countless multi-year tests at a variety of tracks and driving conditions. Indeed, from all of the engineering work and testing, the Future Classic spacer is the lightest and strongest production unit on the market today. And in motorsport terms, adding as little rotational mass as possible (without losing reliability and strength) is the name of the game.

Reason #4: Packaged to Perfection
Echoing Future Classic’s racing enthusiasm and the spacers’ motorsport ties, each kit is fashioned with FC’s gorgeous “livery box”. The Porsche variant wears the infamous “Pink Pig” garb whereas the BMW / A90 Supra box is adorned with the iconic Frank Stella 3.0 CSL art car print. As a reoccurring theme with FC products, the livery boxes give customers a little racing backstory to the designs, a detail that breathes Future Classic through and through.
While other spacers often arrive in disrepair—spacers banging into bolts (causing dents or ruined bolt threads), bolts strewn wildly in the box, or otherwise, the Future Classic box has been constructed with safe delivery in mind. Taking inspiration from the Nest Thermostat packaging, the FC box employs a “two tier” method. Underneath the tabbed box divider, the hardware layer provides a sturdy foundation whereas above it, each spacer is individually wrapped in protective cohesive foam. This specialty foam only adheres to itself, guaranteeing that once you unwrap them, the spacers are ready to install unscathed. No adhesive residue. No fuss.
We chose to upgrade our A90 Supra with a 12mm front and 15mm rear spacer combination, which we felt was the perfect fitment on stock suspension. At the same time, we opted to fit Future Classic’s titanium wheel stud conversion kit for that extra JDM touch. Love the engraved "FC" on each titanium lug nut.
Here are some helpful reference photos for anyone on the fence about spacer sizing:
