Top 5 Easy Mods for Your GR86 or BRZ - No Tune Required
Top 5 Easy Mods for Your GR86 or BRZ (No Tune Required)
The Toyota GR86 and Subaru BRZ are built for drivers; lightweight, rear-wheel-drive, and full of potential. But even with their raw connection and balanced chassis, there’s a ton of opportunity to fine-tune the experience and make the platform your own.
Whether you're just getting started or refining an existing build, here are 6 easy, high-impact upgrades you can install without a tune, all designed to improve the feel, feedback, and form of your car.
1️⃣ Shifter Feel: Short Shifter Kit, Shift Knob, & Reverse Lockout Collar
Upgrading your shifter setup transforms how you engage with the car — and it’s one of the most overlooked mod combos on the GR86 and BRZ platforms. The stock assembly feels loose, long-throw, and a little disconnected. Fixing it is easy and makes a dramatic difference.
Full Shifter Refresh Stack:
- PRSTG x Collective Gruppe Shift Knob – Weighted CNC aluminum with motorsport grip and minimal aesthetic.
- PRSTG Reverse Lockout Collar – Anodized aluminum replacement for factory plastic. Smoother reverse engagement, better fitment.
- Billetworkz Short Shifter - Billetworkz completely redesigned the shift lever in the 86 platform which helps create crisper and shorter throws while retaining factory shift boot and shift knob options.
2️⃣ Lowering Springs or Coilovers (Dial in the Stance and Response)
Nothing changes the look and feel of your car more quickly than dialing in the ride height. From reduced wheel gap to sharper turn-in, this is a foundational mod whether you’re building a street car or weekend canyon carver.
- Fortune Auto 500 Series Coilovers – Rebuildable street/track balance.
- Eibach Pro-Kit Springs – Mild drop, excellent street comfort.
- ST XTA Coilovers – KW-built, adjustable damping with camber plates.
3️⃣ Aftermarket Exhaust (Let the FA24 Engine Sing)
The FA24 flat-four has a great tone, you just can’t hear it through the stock muffler. An aftermarket exhaust system wakes up the car and gives it the presence it deserves.
- Tomei Expreme Ti Type 80 – Ultra-light titanium, aggressive tone.
- HKS Hi-Power Spec-L II – JDM deep tone, zero drone.
- Remark Axle-Back – Affordable, aggressive axle-back option.
4️⃣ Aero Enhancements (Clean Looks, Subtle Function)
The GR86 and BRZ have some of the best proportions of any modern coupe, but a few key aero pieces really sharpen the look. A front lip, side skirt extensions, or a rear spoiler can give the car just enough edge without going over the top.
- CS Style Front Lip – Clean, bolt-on design.
- TRD-Style Rear Spoiler – Perfect OEM+ vibe.
- Verus Rear Diffuser – Track-tested airflow management.
5️⃣ Big Brake Kit (Consistent, Fade-Free Stopping Power)
Even with grippy tires and tight handling, stock brakes can fall short — especially under heat or repeated hard braking. If you're hitting canyons, autocross, or spirited backroads, a big brake kit brings better pedal confidence, shorter stops, and serious visual punch behind the wheels.
- PRSTG 17Z / 18Z Big Brake Kit – Fully customizable Brembo-based kit with caliper color options, 2-piece rotors, and CNC’d brackets made to spec for your chassis.
