Nissan 370Z Performance Parts & Tuning Mods

Top Brands For Nissan 370Z Mods And Upgrades

The Nissan 370Z is well supported by a wide range of leading performance brands. Below you will find top manufacturers for tuning, handling and styling upgrades, offering proven aftermarket parts trusted by 370Z owners and serious track-day drivers alike.

Nissan 370Z Exterior Styling Upgrades

Transform the look of your Nissan 370Z with exterior styling upgrades that add real road presence. From aggressive body kits, spoilers, splitters and diffusers to custom grilles and subtle trim enhancements, you can dial in a sharper, more unique appearance that perfectly matches your build plans and driving style.

Nissan 370Z Suspension & Handling Upgrades

The Nissan 370Z is a great base out of the box, but the stock suspension and tyres can feel a bit crashy over bumps and push into understeer when you really lean on it. Start with quality performance tyres, they make the biggest difference to grip and steering feel, then upgrade to sportier brake pads and braided lines for stronger, more consistent stopping on fast road or track. A decent big brake kit is worth it if you are doing regular track days, as it helps control heat and gives you more confidence deep into the braking zone. Next, look at suspension tuning. Lowering springs or a good set of coilovers will reduce body roll and sharpen the car’s agility, especially when paired with uprated dampers. Stiffer anti roll bars and a front strut brace help calm the 370Z’s tendency to feel a bit loose at the rear, giving more stability on quick direction changes. Polybushes and alignment tweaks finish it off, making the chassis feel tighter, more responsive and genuinely more fun in fast corners without ruining everyday driveability.

Frequently Asked Questions for Nissan 370Z Upgrades

What are the best first performance mods for a Nissan 370Z?

For most Nissan 370Z owners the best first upgrades are a quality cat-back exhaust system, a high flow panel filter or intake kit, and a decent set of performance tyres. These mods free up the engine a little, sharpen throttle response and make the car feel more alive without ruining daily drivability.

After that, lowering springs or coilovers and uprated anti-roll bars are a strong next step. They improve handling, grip and turn in, so you can actually use the power your 370Z already has. It is all about building a balanced package rather than chasing headline horsepower straight away.

How much power can I realistically gain from bolt-on mods and an ECU tune?

With basic bolt-ons like an intake, high flow cats or sports cats, a quality cat-back exhaust and an ECU remap or UpRev style tune, a healthy Nissan 370Z can see a noticeable bump in horsepower and torque. You are not doubling power, but you can expect sharper throttle response and stronger mid-range pull.

On a naturally aspirated setup most owners see modest gains that make the car feel keener rather than wildly faster. The real benefit is how the engine delivers its power, smoothing out flat spots, improving drivability and making the V6 feel more responsive across the rev range.

Is it worth going turbo or supercharged on a Nissan 370Z?

Forced induction on a 370Z, whether turbocharged or supercharged, can give serious performance gains, but it is a big step up in terms of cost, complexity and supporting mods. You will want upgraded cooling, proper fuelling, a stronger clutch, and a very good custom ECU calibration to keep things reliable.

For a fast road or occasional track car, a well sorted naturally aspirated build with intake, exhaust, manifolds, ECU tune, suspension and brake upgrades is often more than enough for UK roads. If you do decide to go turbo or supercharged, budget for quality hardware, professional installation and regular maintenance.

Will tuning and mods affect the reliability of my 370Z?

Light to moderate mods like intake kits, exhaust upgrades, sports cats, coilovers and a sensible ECU remap are generally fine on a well maintained Nissan 370Z, as long as the car is serviced correctly and the mapping is done by a reputable tuner. Many owners run this kind of setup for years without issues.

Problems usually come from poor quality parts, aggressive mapping, lack of cooling or skipping basic maintenance. If you are planning higher power builds, especially forced induction, reliability then depends on using the right supporting performance parts and being realistic about how often you do hard track use or repeated high speed runs.

What wheel and tyre sizes work best on a modified Nissan 370Z?

The 370Z responds well to a mild upgrade in wheel and tyre setup. Many owners move to lightweight 19 inch or 18 inch alloys with wider rubber for extra grip, while trying to keep the overall rolling radius close to stock to avoid upsetting the speedometer and traction systems.

Common fitments are around 9 to 10.5 inches wide at the rear with an appropriate offset, paired with quality performance tyres. Go too aggressive on width or offset and you can run into rubbing issues on arches, especially with lowering springs or coilovers, so it is worth planning your wheel, rim and suspension mods as a package.

Do I need to upgrade brakes if I increase the power of my 370Z?

The factory Nissan 370Z brakes are decent for stock power on the road, but once you start tuning for more horsepower or doing track days, uprated brakes become a smart upgrade. Performance pads, grooved or drilled discs and fresh high temperature fluid can make a big difference on their own.

For harder use or big power builds, a full big brake kit with larger calipers and discs gives better fade resistance and pedal feel. Remember, stopping power is just as important as engine tuning, and good brakes will give you more confidence to use the extra performance safely.

Is a full exhaust system worth it over just a backbox on a 370Z?

A backbox or axle-back exhaust on the Nissan 370Z will mainly change the sound, giving you more character without much in the way of performance gains. If you want real improvements in flow, a full cat-back exhaust, and optionally high flow cats, is usually a better investment.

A properly designed cat-back can reduce weight slightly and improve exhaust flow, which, when combined with an intake and ECU tune, supports a mild increase in power and torque. It also gives you a deeper, more purposeful tone without going silly on volume if you choose the right system.

Final Thoughts On The Nissan 370Z

The Nissan 370Z is a proper old-school driver’s car, with a strong naturally aspirated V6, rear-wheel drive and a chassis that loves being pushed. Out of the box it is a fun road car, but you can feel the factory compromises in areas like slightly soft suspension, average brake feel and heat management that struggles with hard use. That is exactly where well chosen performance parts come in, letting you sharpen what is already a solid base without ruining its daily manners. With intake, exhaust and ECU tuning, the 370Z responds nicely, freeing up a bit of power, better throttle response and a more involving soundtrack without going wild. Add in cooling upgrades like uprated radiators or oil coolers and you can keep temps under control on spirited drives or track days. Many owners also address the stock clutch and concentric slave cylinder, fitting stronger, more reliable parts so the drivetrain can cope with harder use. Handling is where the Nissan 370Z really wakes up with the right suspension mods. Quality coilovers or sport springs, uprated anti-roll bars, fresh bushes and a good alignment transform body control and turn-in while still being totally livable on UK roads. Match that with better pads, discs, lines and a lighter set of wheels or alloys and you get a car that stops harder, grips better and feels more precise everywhere. Visually, small styling tweaks like a subtle body kit, splitter, rear spoiler, or a more aggressive wheel and tyre setup really suit the 370Z’s muscular shape. The key is balancing performance upgrades with reliability and comfort, building a car that can handle the commute, the B-road blast and the occasional track session without complaint. Treated right and modified sensibly, a sorted 370Z feels like the car Nissan always meant it to be, and it becomes a very personal expression of how you like to drive. This is your chance to take a great base and turn it into a unique, properly sorted Z that fits your own idea of the perfect build.
