How to Get Fusion Parts in CSR2 – Best Ways to Upgrade Cars

What Fusion Parts Actually Do

Most people think Stage 6 parts are the end of building a car in CSR2. They're not. Fusion parts are what take a car from 'fully upgraded' to actually fast. They fit into fusion slots on each car and boost specific things — acceleration, top speed, nitrous — stuff that regular stage upgrades don't touch.

How many fusion slots a car has depends on its star rating. A 1-star car barely has any. A 5-star version of the same model can have quite a few more. That's one of the main reasons players chase higher-star versions of cars they already own — more slots means more room to push performance higher.

They're Manufacturer-Specific — And That's the Annoying Part

Here's what makes farming fusion parts so frustrating: they're brand-locked. McLaren parts only work on McLarens. Bugatti parts only go on Bugattis. There's no mixing brands, and CSR2 has over 50 manufacturers.

So even if you're opening bronze crates regularly, most of what drops will probably be for brands you're not even building right now. You could end up with 30 BMW parts when you actually need Ferrari ones, and there's no way to convert between them. The more specific your build target, the more annoying this gets.

Rarity Levels — Common, Rare, and Epic

Not all fusion parts are the same. There are three rarity levels, and the difference matters once you're racing seriously.

Common parts are the most basic. You'll get a lot of them — they're the most frequent drop from bronze crates. Fine for early builds or lower tiers, but they won't take a car to its best.

Rare parts are noticeably better and don't drop as often. If you're putting together a proper T4 or T5 car, Rares are usually what you're aiming for. You can get them through consistent crate grinding, but it takes time.

Epic parts are the rarest and the strongest. When one drops from a bronze crate it's genuinely exciting — they're that uncommon. For cars you race in Showdowns, T5 Live Races, or Crew Championships, having Epic fusions in the right slots makes a real, measurable difference. Getting a full set for one specific car is a serious grind.

Bronze Crates — Where Most Players Start

Bronze crates are the main source of fusion parts. Go to Rare Imports, open a crate — you always get at least one fusion part. Unlike Stage 6 parts (roughly a 10% chance per crate), fusions are guaranteed every single time. That's why bronze crate grinding is the go-to method for most people.

You also get a free bronze crate every four hours just for logging in. Easy to forget, but if you're consistent about claiming them, those free crates add up fast over a week. Want to farm harder? Spend bronze keys to open more.

The catch is that the brand of parts you get is totally random. You can't filter by manufacturer in normal gameplay — it's pure RNG. More crates means better odds of eventually getting what you need, but there's no guaranteed timeline.

Stripping Cars — A Better Way for Specific Brands

If you need parts for a specific brand, stripping cars is way more reliable than hoping crates cooperate. When you dismantle a car, you get its fusion parts — and they'll be from that manufacturer. Strip a McLaren, get McLaren fusions. Simple.

The practical way to use this: find the cheapest Dealership car from the brand you need, buy it, strip it. If there's a model available for a few hundred thousand in cash, you can repeat this multiple times to stack up brand-specific parts without spending any keys.

Not every brand has a cheap option in the Dealership, so this won't always work. But when it does, it's much faster than waiting for random bronze crate drops to eventually hit the right manufacturer.

Events, Milestones, and Supply Cups

Events are another solid source. Seasonal and story events usually have milestone reward tracks that include fusion parts — sometimes even brand-specific ones tied to whatever car is featured that cycle.

Supply Cups are especially useful here. These run during active event windows and often hand out parts for the current Prestige Cup car or the featured event vehicle. If you're building that exact car, running Supply Cups during the event window is one of the few ways to target specific parts without stripping.

Being in a good crew helps too. Crew Cups and the Weekly Elite Cup sometimes give out fusion parts for crews at higher tiers. You just get more stuff consistently when you're in an active crew versus going solo.

Moving Parts Between Cars

A lot of newer players don't know this: you can pull fusion parts off one car and move them to another — as long as it's the same manufacturer. It costs gold to remove them, and the price goes up with rarity. Taking out an Epic part costs more than pulling a Common one.

This is useful if you have an old car sitting in your garage that you've heavily fused but don't race anymore. Pull the parts, put them on your current build. Costs some gold, but it's faster than farming from scratch.

Why It Gets Painful at Higher Tiers

At Tier 1 and 2, fusion farming is manageable. Cars are cheaper to strip, builds are simpler, and it doesn't really matter if your fusions aren't perfect. Once you hit T4 and T5, everything gets harder and more expensive.

A properly fused T5 car can take dozens — sometimes hundreds — of bronze crate pulls to build out, and most of those pulls drop parts for brands you're not even working on. Add the gold cost of fixing misapplied fusions, the randomness between sessions, and the cost of repeatedly stripping Dealership cars, and it becomes a real time and resource drain. That's usually when players start looking for other options.

Some players at that point use a [csr2 mods](https://csr2modding.com) service to get targeted parts delivered straight to their account — no crate RNG, no waiting weeks for the right drops. It's not for everyone, but if you know exactly what you're building and just want to get it done, it's worth knowing that option exists.

A Few Tips If You're Farming the Normal Way

Focus on one manufacturer at a time. Spreading parts across every car in your garage means you barely make progress on any of them. Pick the car you're actually racing, farm parts for that brand, finish it, then move on.

Check the Dealership before stripping sessions. The selection changes, and what's available at a reasonable cash price shifts. Cars in the 500k to 1M range that yield 8–12 parts when stripped are solid value for targeted farming.

Think before you apply fusions. Putting a part in the wrong slot — or on a car you're not racing — means spending gold to fix it later. Figure out the right layout before you start slotting anything in, especially on cars with only a few slots to work with.
