Toyota Boss Kit Buying Guide: Matching a Hub to Your Model

Toyota, Lexus and Scion share more steering column architecture across model lines than most brands, which is handy for parts availability, but it also means the model name alone does not always tell you which hub fits. This guide walks through what to check on your specific model before you buy, which hub range fits it, and what the law actually says about running one.

If you have already picked a hub and want the full install walkthrough, splines, PCD, torque specs, and the step by step fit, see our Boss Kit Fitment Guide.

Featured in this guide

The cleanest pick in the Toyota range if your car is on this list. It keeps horn and turn signal function in almost all applications, comes with resistors where your car needs them, and is built specifically for the 86 and BRZ rather than a broad generic fitment. Used as the worked example throughout this guide.

Start here: standard hub or short hub

Before you look at any specific model, decide what you are building for.

Standard hub: bolts a 6 bolt wheel straight to your column. Keeps horn and indicator function in most cases. This is the right choice for a street car or a track car that still needs working indicators.

Short hub with quick release: removes bulk and weight, and is built to pair with an NRG Quick Release. The RACE SHORT hub in particular drops the horn attachments entirely and has no 6 hole pattern at all, so it is quick release only. These hubs are motorsport and off road use only, not for a car you plan to indicate on the way to the track.

Model by model: which hub fits your Toyota

A note on shared platforms

Toyota, Lexus and Scion badge a lot of shared engineering under different names, and the 86 and BRZ are literally the same car built alongside Subaru. If your model is not listed by name above but shares a platform with one that is, do not assume the same hub fits, ask us to confirm first. The RACE SHORT hub's broad compatibility list above is the supplier's own claim across three decades of models, and while wide compatibility is common on this platform family, we would rather confirm your specific year and model than have you find out it is wrong after fitting.

Is it legal to run a boss kit in Australia?

This is one of the most common questions we get asked about boss kits.

Fitting a boss kit is not the problem. Using one to remove or bypass safety equipment your Toyota was built with, most importantly the airbag and its wiring, is. That is the whole distinction, and it is why hubs like the RACE SHORT quick release below are sold for motorsport and off road use only rather than as a road legal fitment. Ignore that and you are risking fines, and giving your insurer a reason to walk away from a claim if something goes wrong.

The basis for this sits in the Australian Design Rules, the national standards your Toyota was certified against when it was built. ADR 10 covers the steering column specifically, and exists to reduce the risk of crushing or penetrating injury to the driver in a frontal impact. Once the car is registered and on the road, state and territory law generally expects it to keep meeting the ADRs it was built to, or something later. Strip the airbag related parts out of that steering column assembly and the car is no longer in the configuration it was certified under, which is the actual reason this matters, not just an insurance technicality.

None of this rules a boss kit out for a road car, the opposite in fact. A hub correctly rated for your model that keeps the airbag system intact is a completely normal, legal fitment. The line sits at removing or bypassing what came from the factory. If you are not sure whether a particular hub keeps your Toyota's airbag steering wheel intact, ask us before you buy rather than guessing.

Horn and indicators: what you keep, what you lose

Same principle as the rest of the range. The standard hubs, once the Corolla SKU conflict is resolved, keep your factory horn and indicator function, same as any bolt in hub. The RACE SHORT hub removes the horn attachments entirely and has no 6 hole pattern, built purely for a quick release race wheel on a car that is not driven on public roads. SRK-125H, SRK-124H and SRK-120H sit in between, retaining horn and turn signal function in most applications, with resistors included where your car needs them.

If your Toyota is driven on the street at all, a hub that removes indicators and horn function is the wrong choice, regardless of the weight saving, and regardless of whether it can be physically fitted.

Quick reference: what you need before you order

• Confirm your exact model, generation and year, shared platforms do not always mean shared hubs
• Decide standard bolt on versus quick release before you compare price
• Confirm whether you need working horn and indicators for road use
• Confirm the hub you are looking at is road legal if the car is driven on public roads
• If your model only appears in a generic "various" listing, contact us to confirm before ordering

Toyota Boss Kit FAQs

Can I use a quick release hub on a road registered Toyota? 

The quick release only hubs in this range are built for motorsport and off road use, and the RACE SHORT hub in particular removes horn wiring entirely and has no 6 hole pattern. Running one on a road registered car in place of factory safety equipment is not legal. Check the specific product notes for your model before fitting one to a road car.

Is it legal to remove my airbag to fit a boss kit? 

No. Removing or bypassing factory safety equipment, including airbags, is against the rules for any vehicle used on Australian roads and can void your insurance. A correctly rated boss kit that keeps your airbag and safety systems intact is a normal, legal fitment.

Why do two Corollas need different boss kits? 

In this case, we genuinely are not sure yet, which is exactly why we have not published a SKU for the Corolla in this guide. Toyota changed Corolla generations several times across the decades this hub range covers, and until we confirm which generation each supplier SKU actually fits, we would rather leave the gap than guess.

What if my model is not listed here, or only shows up in a generic listing? 

Contact us with your model, generation and year and we will confirm the correct hub before you buy.
