Subaru BRZ Performance Parts & Tuning Mods

Top Brands For Subaru BRZ Mods

The Subaru BRZ is well supported by leading performance manufacturers, with a wide range of quality tuning parts, handling upgrades and styling mods available. Below you will find top brands trusted by BRZ owners for reliable, track tested aftermarket components.

Subaru BRZ Exterior Styling Upgrades

The Subaru BRZ already looks sharp, but a few well chosen styling mods can really set it apart. From body kits, splitters and rear diffusers to spoilers, custom grilles and other exterior trim upgrades, you can dial in a more aggressive, track-inspired look that feels truly your own.

Subaru BRZ Suspension & Handling Upgrades

The Subaru BRZ is already a sharp little coupe, but there is a lot of easy handling potential left on the table. Start with tyres and brakes, as good rubber and performance brake pads instantly improve grip, stopping power and confidence on both road and track. A set of quality performance tyres will make the steering feel more precise and predictable, while uprated pads, fluid and braided lines help tackle brake fade on spirited drives or track days. From there, look at suspension tuning. The BRZ can feel a touch soft and underdamped from the factory, so lowering springs or a decent set of coilovers will cut body roll and give you more direct feedback through the chassis. Matched dampers, plus uprated anti roll bars, strut braces and fresh polyurethane bushes, tighten everything up, improving agility and stability mid corner. Do the upgrades in stages, test the balance, then fine tune ride height and alignment to suit your driving style.

Frequently Asked Questions

What are the best first performance mods for a Subaru BRZ?

If you are just starting to tune your Subaru BRZ, a good base set of upgrades is a cat back exhaust, a panel filter or intake kit, and a proper ECU tune to tie it all together. These breathing mods help the FA20 engine respond a bit sharper and sound far better without going overboard.

Suspension is just as important as power. A set of quality lowering springs or coilovers, plus uprated anti roll bars, will tighten up the chassis and make the car feel more planted on road and track. It is one of the most rewarding early changes you can make.

Is it worth remapping / tuning a stock naturally aspirated BRZ?

An ECU remap on a stock Subaru BRZ will not give huge horsepower gains, but it can still be worthwhile. You can expect a crisper throttle response, a smoother power curve and small but noticeable improvements in mid range torque, especially when combined with an exhaust and intake.

The real benefit is how the car drives rather than headline dyno numbers. A good BRZ tune will refine the factory calibration, sharpen response, and often improve driveability on both fast road and daily use.

Should I go turbo or supercharger on my Subaru BRZ?

Both turbo kits and supercharger kits can transform a BRZ, but they suit different driving styles. Turbocharger setups usually offer more peak power potential, ideal if you are chasing bigger numbers and plan to upgrade fuel system and clutch as well.

Supercharger kits tend to deliver a more linear power delivery that feels closer to a bigger naturally aspirated engine, which many BRZ owners prefer for track days and fast road. Either route needs proper supporting mods like an upgraded clutch, cooling, and a custom ECU map to keep things reliable.

How does tuning affect reliability on a BRZ?

Mild mods such as exhaust, intake, and a sensible ECU tune are generally safe on a healthy Subaru BRZ, provided the car is well maintained and the mapping is done by a reputable tuner. Regular oil changes and good quality fuel are essential.

Forced induction setups increase stress on the engine and drivetrain, so reliability depends heavily on boost level, cooling, and how the car is driven. Keep power goals realistic, fit supporting performance parts, and stick to strict servicing intervals to reduce the risk of problems.

What wheel and tyre sizes fit well on a Subaru BRZ for fast road use?

A popular upgrade is 17x7.5 or 17x8 alloys with around ET35 to ET45 offset, paired with 215 or 225 width performance tyres. This setup keeps the car light and responsive while giving a bit more grip and a nicer stance compared to the factory wheels.

Many owners also run 18 inch rims for looks, typically 18x8 to 18x8.5 with 225 or 235 width tyres. Just be aware that heavier wheels and tyres can blunt acceleration and ride quality slightly, so choose lightweight alloys where possible.

How much does it cost to tune a Subaru BRZ?

Costs vary a lot based on how far you want to go. As a rough guide, a basic package with a cat back exhaust, intake and an ECU remap can sit in the region of a few hundred to around a thousand pounds, depending on the brands and whether you include fitting.

Forced induction builds with a turbo or supercharger kit, fueling upgrades, clutch and full exhaust can run into several thousand pounds once parts, mapping and labour are included. It is worth planning a staged tuning route so you can spread the cost and keep the car usable between upgrades.

Is the Subaru BRZ good for track days and what track focused mods should I consider?

The BRZ is a strong base for track use thanks to its low weight and balanced chassis. For occasional track days, start with uprated brake pads, high temperature fluid, performance tyres and a good geometry setup. These mods improve consistency and confidence without making the car harsh on the road.

For more serious track work, consider coilovers with adjustable damping, additional camber adjustment, and an oil cooler to help manage temperatures during long sessions. Combine this with a reliable tune and you will have a very capable track toy that still works as a daily driver.

Final Thoughts On The Subaru BRZ

The Subaru BRZ is all about balance, feedback and fun, and that is exactly why it responds so well to the right performance parts and tuning upgrades. Out of the box it is light, playful and confidence inspiring, but most owners quickly find themselves wanting a little more bite from the engine, brakes and chassis. That is where a sensible mix of bolt-ons, ECU mapping and supporting mods turns the car from “great road car” into a properly sorted fast road and track toy. You keep the BRZ character, just sharpened and more eager everywhere in the rev range. Stock suspension can feel a bit soft and floaty when you push on, and the standard alignment is conservative, so coilovers, quality springs or even just uprated dampers and bushes make a big difference to turn in and stability. Cooling and heat management are another weak spot when you start adding power or running hard on circuit, so radiators, oil coolers and better brake hardware are common upgrades that keep temperatures in check. The clutch and drivetrain are generally fine at factory power, but with turbo or supercharger kits, most enthusiasts move to a stronger clutch and better fluids for long term reliability. Styling tweaks and wheel upgrades let you finish the build with a look that matches the performance, from lightweight alloys and sticky tyres to subtle aero parts that actually work. The trick is to choose parts that complement each other, so you get more speed and grip without ruining daily comfort or reliability. With a balanced package of power mods, chassis tuning and cosmetic touches, a Subaru BRZ becomes a seriously rewarding driver’s car that still behaves on the commute. Treat it as a platform to personalise, and you can build a BRZ that feels uniquely yours every time you turn the key.
