The B9 Audi S5 is a stunning blend of luxury and performance, but for enthusiasts, there’s always room for improvement. Whether you’re after more power, a sportier look, or better handling, here are the top five modifications to take your B9 Audi S5 to the next level.
1. Performance Tune (ECU Remap)
One of the most impactful upgrades for the B9 Audi S5 is an ECU remap or performance tune. The factory 3.0L turbocharged V6 engine has untapped potential, and tuning it can unlock significant gains in horsepower and torque.
Benefits:
- Increases power by up to 80–100 HP and 100+ lb-ft of torque.
- Improves throttle response and turbo spool time.
- Customizable maps for fuel efficiency or maximum performance.
Popular Brands:
- APR, Revo, Unitronic, or Cobb.
Cost:
- £500–£1,000 depending on the tuner and software.
2. Aftermarket Exhaust System
An aftermarket exhaust is the key to unlocking a more aggressive sound from your S5 while improving performance by reducing exhaust backpressure.
Benefits:
- Enhanced Sound: From deep growls to crackles and pops.
- Increased Performance: Gains of 10–20 HP due to better airflow.
- Weight Reduction: Lighter materials like stainless steel or titanium.
Options:
- Cat-Back Systems: Replace everything from the catalytic converter back.
- Downpipes: A high-flow or catless downpipe amplifies sound and power.
Popular Brands:
- Milltek, Cobra, or Remus.
Cost:
- £800–£2,500 depending on the system.
3. Suspension Upgrades (Lowering Springs or Coilovers)
The S5’s factory suspension is comfortable but leans more toward luxury than sport. Lowering the car enhances both aesthetics and handling.
Benefits:
- Improved Handling: Reduces body roll and improves cornering stability.
- Sporty Stance: Lower ride height for a more aggressive look.
- Custom Adjustability (with coilovers): Fine-tune ride height and damping.
Options:
- Lowering Springs: Eibach Pro-Kit or H&R for a simple, cost-effective drop.
- Coilovers: KW Variant 3 or Bilstein for performance and adjustability.
Cost:
- Springs: £200–£400.
- Coilovers: £1,000–£2,500.
4. Aftermarket Wheels and Tires
Upgrading the wheels and tires not only improves aesthetics but also enhances grip and performance.
Benefits:
- Custom Look: A wide range of styles to suit your taste.
- Improved Handling: Better tire compounds and wider widths increase grip.
- Weight Reduction: Forged wheels are lighter than stock alloys.
Recommended Sizes:
- 20-inch wheels with wider tires (e.g., 255/30/20 or 265/30/20).
Popular Brands:
- Wheels: Vossen, Rotiform, or BBS.
- Tires: Michelin Pilot Sport 4S or Pirelli P-Zero.
Cost:
- Wheels: £1,000–£3,000.
- Tires: £500–£1,200.
