Top 5 Mods for the 2020+ Toyota Supra (A90/A91): Performance & Style Upgrades
The 2020+ Toyota GR Supra (A90/A91) is an impressive sports car from the factory, but enthusiasts know there's always room for improvement. Whether you want to unleash more power, sharpen the handling, or give your Supra a personalized look, the aftermarket has you covered.
In this post, we’ll highlight the Top Five Mods - covering performance upgrades and style enhancements - that will take your Supra to the next level. You’ll get all the key details: what each mod does, popular brands, real-world gains, and pro tips for installation.
1. ECU Tuning and Software Upgrades
One of the most impactful upgrades for the GR Supra is ECU tuning -reprogramming the engine’s brain to safely unleash extra power. The B58 turbo inline-6 has tons of untapped potential, and a proper tune optimizes boost, fuel, and timing for huge gains.
- Power Gains: +50–80 HP with Stage 1 tuning on 93-octane
- Key Benefits: Sharper throttle, faster acceleration, optional exhaust burbles
- Pro Install Tip: Flash via OBD-II at home or opt for plug-and-play piggyback devices
Popular Brands: BOOTMOD3, EcuTek, COBB Accessport, Burger Motorsports JB4
Customer Reviews: "Transformative." "Feels like the car Toyota should have built." Owners consistently rank ECU tuning as the most satisfying upgrade.
Pricing: $600–$1,200 for software/devices. Piggybacks: ~$500–$800.
Installation: Moderate (most are DIY-friendly)
2. High-Performance Exhaust System (Downpipe & Cat-Back)
A high-performance exhaust wakes up the Supra’s sound and power. Swapping the restrictive downpipe and adding a freer-flowing cat-back reduces backpressure, helping the turbo spool faster while delivering that deep, aggressive growl.
- Power Gains: +10–25 HP on stock, up to +100 HP with tune
- Key Benefits: Enhanced sound, quicker throttle, turbo spool
- Pro Install Tip: Consider high-flow catted downpipes to avoid CEL issues on street builds
Popular Brands: Akrapovič, HKS, AWE, Armytrix, Remus
Customer Reviews: "Smiles every drive." "Night and day difference." Owners love the sound transformation and improved response.
Pricing: Downpipes $300–$800; full systems $1,500–$3,000+
Installation: Moderate (requires under-car work)
3. High-Flow Cold Air Intake System
Upgrading the intake is a popular and easy way to help your Supra breathe better while adding more turbo sound and personality. The stock airbox works, but a high-flow cold air intake reduces restriction, feeds cooler air to the turbo, and delivers a noticeable improvement in response and sound.
- Power Gains: +5–15 HP (dyno proven with quality intakes)
- Key Benefits: More intake/turbo sound, better throttle response, complements other mods
- Pro Install Tip: Go for intakes with proper heat shielding to avoid heat soak
Popular Brands: aFe Power, Injen, Eventuri, HKS, K&N
Customer Reviews: “Sounds like a real turbo car now.”
Pricing: $300–$1,000 depending on brand and materials
Installation: Easy (bolt-on DIY friendly)
4. Suspension Upgrades (Lowering Springs & Coilovers)
The Supra is already a sharp handler, but suspension upgrades take things to the next level - both in looks and performance. Lowering springs offer a fixed drop while coilovers give you full adjustability for ride height and damping.
- Handling Gains: Lower center of gravity, reduced body roll
- Visual Gains: Eliminates wheel gap for an aggressive stance
- Pro Install Tip: Always realign after lowering
Popular Brands: Eibach, H&R, KW Variant 3, BC Racing, Ohlins
Customer Reviews: "Should have come from factory this way."
Pricing: Springs: $250–$500. Coilovers: $1,000–$3,000+
Installation: Moderate–Advanced
5. Aftermarket Wheels & Tires Upgrade
No build is complete without standout wheels. Upgrading to lightweight, wider aftermarket wheels transforms the Supra's look and improves handling, acceleration, and braking by reducing unsprung weight.
- Performance Gains: Sharper handling, quicker acceleration
- Visual Gains: Personalized stance, show-ready style
- Pro Install Tip: Ensure correct offset & brake clearance
Popular Brands: Volk, Advan, BBS, Titan7, HRE
Customer Reviews: “Game changer for looks and feel.”
Pricing: $2,500–$5,000+
Installation: Easy (bolt-on)
