The MOZA SR-P Accessory Kit is the little pack that aims to transform an already decent crankset into something far more serious. We're talking here about an upgrade kit for the MOZA SR-P crankset: harder springs, elastomer blocks for the brake pedal, anti-slip plates... The idea is simple: add realism, especially to braking, without having to change crankset or go straight to a top-of-the-range load cell model.

The immediate attraction is the promise of a firmer, more progressive brake, like a racing pedal, for a price and complexity far more contained than a complete hardware change. For many PC and console gamers with a basic SR-P, this kit represents a kind of easy-to-install "sport mode".

So my angle of analysis is clear: does this kit really change braking feel and car control, or is it just a cool but dispensable gadget? I'm going to concentrate on the feel underfoot, the perceived quality of the new parts, ease of installation and, above all, the impact on lap times and consistency. After all, you want to brake later, harder, and with more control. That's exactly where this type of kit should make a difference.

Design and manufacturing

The MOZA SR-P Accessory Kit comes in the form of a set of additional parts dedicated to the SR-P crankset. These include springs of varying hardness, elastomer blocks to modulate brake pedal travel and resistance, and a number of elements designed to improve heel and toe stability. Visually, everything remains in the MOZA tradition: metal, clean finishes, a sober, slightly "industrial" look.

In hand, the springs are strikingly rigid. You immediately sense that you're no longer dealing with the suppleness of an entry-level crankset. The rubber blocks (or equivalent elastomer compounds) give an impression of correct density, neither too soft nor too plastic. The metal parts remain consistent with the crankset itself, which is reassuring in terms of durability.

Assembly inspires confidence: nothing looks cheap or fragile. Once installed, the new components integrate cleanly, without excessive play or parasitic vibrations. You really get the impression of an "upgraded" pedalboard, rather than a rough aftermarket DIY job. It's clean, crisp and consistent with the rest of the MOZA ecosystem.

What may be slightly disappointing is that, fundamentally, we remain on a base that is not a load cell. The feel has clearly improved, but you don't magically reach the level of a competition pedalboard with a dedicated pressure sensor. Compared to other upgrade kits for mid-range cranksets, the MOZA SR-P Accessory Kit is in the middle of the pack: serious, well-built, but limited by the philosophy of the original crankset.

Settings, customization and compatibility

The aim of this kit is to let you shape the behavior of your SR-P crankset to your liking. MOZA offers different springs and elastomer block configurations, so you can go from a fairly progressive, tolerant brake to a much firmer, single-seater or modern GT style. Adjustment is mechanical: block position, spring selection, sometimes preload adjustment. Nothing insurmountable, but you need a few minutes to understand the logic.

The learning curve is reasonable. If you've ever used an adjustable crankset, you'll get the hang of it in no time. If it's your first kit of this type, you'll probably go through several trials before finding your "sweet spot". Honestly, that's part of the fun: you adjust, you test, you fine-tune. You quickly feel when you've found the compromise that suits your braking style.

On the software side, everything runs through the MOZA ecosystem on PC, which unsurprisingly recognizes the SR-P pedalboard. The kit itself doesn't change compatibility, so if your pedalboard is already running on your current platform (PC or console via a compatible MOZA base), the Accessory Kit poses no problem. It's not a stand-alone product, it's a pure hardware complement.

In terms of the ecosystem, we're obviously still in the MOZA family: used with a MOZA base and a MOZA steering wheel, the whole package is very coherent. The SR-P crankset equipped with the kit becomes a more serious basis for a mid-range cockpit. It's not an entry point, but clearly a way of prolonging the life of your crankset and postponing the moment when you'll have to consider switching to a more expensive load cell or hydraulic kit.

Sensations in play

It's on the virtual track that the MOZA SR-P Accessory Kit has to justify its existence. The most striking change, of course, concerns the brake pedal. From the very first laps, the stroke is firmer and more consistent. There's less of that "road pedal" feeling, and much more of the impression of working against progressive resistance, which becomes denser at the end of the stroke.

When braking hard, proportioning becomes more intuitive. Where the original SR-P can quickly give the impression of floating, especially if you brake hard and late, the kit brings real structure to the pedal. You feel the pressure levels better. The foot has its bearings. You know when you're close to locking the wheels, and you can stay precisely in that zone. You immediately understand what the car is doing.

When cornering, especially when braking downwards, the difference is clear. Mass transfer becomes more legible, more reproducible. You can brake hard on the line, then release progressively, while maintaining a consistent feel. Compared with an unmodified crankset, I found it much easier to maintain a stable trajectory when releasing the brake to register the car. The kit really helps you gain finesse and confidence.

Grip reading improves especially when braking at the limit. We're not talking about FFB here, but the way the brake responds underfoot helps you interpret what's happening at the front wheels. It's easier to sense when you're overdoing it, or on the contrary, when you can brake a little later and a little harder. On vibrators, the stability of the right foot is better: the extra firmness limits involuntary micro-movements of the ankle. Pressure is better maintained, even when the car is moving.

On long sessions, this type of firmer configuration can be tiring if you come from an ultra-soft crankset. But the Accessory Kit offers enough combinations to find a setting that's demanding but not calf-destroying. Once adjusted, consistency is clearly superior. One lap follows another, with fewer variations in braking points. This is where the kit really changes the experience: you're no longer fighting with the pedal, you're concentrating on your trajectory.

During quick corrections, especially on nervous cars or in variable grip conditions, the firmer brake pedal helps maintain fine control. You can adjust pressure in a fraction of a second without "mashing" the pedal by mistake. This precision at high action speeds gives a superior feeling of control, even if you're not on the level of a very good high-end pedal load cell.

Compared with an original crankset or other less advanced spring models, the MOZA SR-P with this kit really feels like a step up. It doesn't achieve the brutality and pure linearity of premium load cell cranksets, but it does come very close in terms of overall feel. Compared with a more powerful, higher-end setup, there's still a clear gap in terms of ultimate precision and sensitivity to small variations in pressure, but the Accessory Kit reduces the difference sufficiently to make the SR-P very relevant for an intermediate or advanced sim racer who doesn't want to blow his budget.

Who's it for? What we like, what we don't like

The MOZA SR-P Accessory Kit is aimed above all at owners of the SR-P crankset who are beginning to feel the limitations of the original brake. Typical profile: motivated PC or console gamer, already well invested in sim racing, who rides regularly, does time trials, league championships or simply wants better control during races. A complete beginner may appreciate the gain, but will benefit most from this kit once the basics of braking have already been acquired.

What I appreciate most is the marked improvement in brake feel. The gain in firmness and progressiveness means you can brake later with greater confidence. The other strong point is the modularity: several possible combinations, a real ability to adapt behavior to your riding style. Last but not least, overall build quality is at the level expected of a product designed to last. Nothing gives the impression of needing to be replaced after a few weeks.

The limitations come mainly from the nature of the original pedalboard. Despite the upgrade, you can't turn an SR-P into a miracle high-end crankset: absolute precision remains below that of a good specialized load cell. Second point: you have to get your hands dirty. For some, these mechanical adjustments and successive assemblies/disassemblies to test different configurations may seem tedious. Finally, everything remains locked up in the MOZA ecosystem: we're talking about a relevant investment only if you intend to stay with this crankset for a while longer.

In terms of value, the SR-P Accessory Kit is a smart upgrade. It's not the cheapest accessory in your setup, but the gain in braking confidence and consistency makes it a sensible investment if you ride a lot and already get the most out of your current equipment. It's less of a financial commitment than a complete crankset change, while providing a real qualitative leap in feel.

Verdict

The MOZA SR-P Accessory Kit doesn't change the very nature of your crankset, but it clearly pushes its limits. In a mid-range setup, it's typically the upgrade that takes your braking from "okay" to "really usable" to work on your brake points, consistency and confidence. The SR-P crankset becomes more serious, more demanding, but also more rewarding to master.

On the market, this kit is positioned as a well-thought-out mid-range upgrade: not esoteric, not oversized, but sufficiently sophisticated to make a real difference on the track. It's aimed at sim racers who are already somewhat committed, who know their needs and who clearly feel the limits of a brake that's too soft or too approximate. For the very occasional beginner, it won't be a priority.

If you plan to migrate quickly to a high-end load cell or hydraulic crankset, this kit may be an unnecessary detour. On the other hand, if you want to solidify your current setup, make your SR-P crankset more profitable and gain a step up in braking precision, the MOZA SR-P Accessory Kit makes perfect sense. If you're looking to make your braking firmer, more legible and more consistent with high-performance riding, this product can clearly make the difference in your setup.
