The Honda Civic Type R FL5 is the most capable Type R Honda has ever produced, delivering 325bhp from the turbocharged K20C1 with Brembo brakes and an adaptive damper system already fitted as standard. It is an exceptional car straight from the factory and that foundation makes it an outstanding platform to build on. This guide covers the most effective upgrades for the FL5 from brands that know the Honda platform inside out.
Quick Verdict
Start with Dixcel Z Type brake pads paired with SD slotted discs before anything else. Spoon lowering springs are the no-hassle suspension upgrade that works with the factory dampers and drops the car without compromising daily comfort. For intake the Spoon air filter is the clean OEM+ choice or go all-in with the Eventuri carbon system for the ultimate engine bay upgrade. The Fujitsubo A-RM+C titanium exhaust is the top-end choice for sound and quality on the FL5 and is the one to buy if budget allows.
1. Brake Upgrades
The FL5 runs Brembo 4-piston front calipers as standard which provides a strong braking foundation. Under sustained hard use the stock pads are the weak point and fade sets in sooner than the caliper hardware deserves. Upgraded pads paired with high-temperature fluid and quality discs is the first modification any FL5 owner should make before a circuit.
| Pad | Best For | Cold Bite | Fade Resistance | Price Point |
|---|---|---|---|---|
| Dixcel Z Type | Fast road and track | Excellent | Excellent | ££ |
| Spoon Sports Brake Pad | Fast road and OEM+ | Strong | Strong | ££ |
| PBS ProRace | Regular track use | Good once warm | Excellent | ££ |
- Dixcel Z Type Brake Pads — the Torque GT recommendation for the FL5. Proven in Super GT and Super Taikyu competition with consistent cold bite and strong fade resistance across the full operating range. The go-to first upgrade for any FL5 used on road or track
- Spoon Sports Brake Pads — developed specifically for Honda platforms with a compound that suppresses resin gas production under repeated braking. Works well from cold and is gentler on rotors than track-biased compounds. Spoon also offer a dedicated Circuit pad for track-only use
- PBS ProRace Brake Pads — ceramic graphite compound with excellent modulation and race-proven consistency across European motorsport. Needs heat to perform at its best so less suited to daily driving
Torque GT take: Dixcel Z Type paired with SD slotted discs gives the best balance of daily usability and track-ready performance on the FL5. For dedicated track use PBS ProRace delivers race-proven consistency.
Brake Discs
Upgraded pads perform best alongside quality discs. The Dixcel SD slotted disc is the Torque GT recommendation for the FL5 delivering maximum bite and heat management under sustained hard braking. Worth noting that slotted discs will increase pad wear rate slightly so factor that into running costs on a daily driven car.
- Dixcel SD Slotted Discs — the performance choice for road and track use. Maximum bite and heat management and the recommended pairing with Z Type pads on the FL5
- Dixcel PD Discs — cross-drilled pattern with strong all-round performance and good longevity for drivers who prefer a less aggressive option
Brake Fluid
High-temperature brake fluid is non-negotiable for any FL5 used at circuits. Stock fluid boils under sustained hard braking which introduces a spongy pedal at exactly the moment you need confidence. Dixcel RF328 and Motul RBF700 both raise the boiling point ceiling significantly and are a straightforward bleed-in at home or in the workshop.
2. Suspension Upgrades
The FL5 adaptive damper system is genuinely impressive from the factory. A quality suspension upgrade builds on that foundation with better body control, more precise steering response and the ability to dial in setup to suit how the car is driven. For drivers who want improved stance without changing dampers Spoon lowering springs are the natural starting point.
| Option | Best For | Adjustability | Price Point |
|---|---|---|---|
| Spoon Lowering Springs | Daily road use | None | £ |
| TEIN Coilovers | Fast road and track | Full damping adjustment | ££ |
| KW V3 Coilovers | Dedicated track and fast road | Independent compression and rebound | £££ |
| Öhlins Road and Track | Top-end performance | Full motorsport specification | ££££ |
- Spoon Lowering Springs — drops ride height by approximately 20mm while retaining factory ride quality and handling balance. Built to work with the stock adaptive dampers or alongside Spoon dampers. The right starting point for daily driven FL5s where comfort matters
- TEIN Coilovers — the Torque GT go-to coilover brand. Full damping adjustment with a balanced setup that works across road and track without compromising daily use
- KW V3 Coilovers — independent compression and rebound adjustment with German build quality. The recommended step up for FL5 owners who attend circuits regularly and want to fine-tune properly
- Öhlins Road and Track — widely regarded as the best suspension available for the FL5. Motorsport-derived damping with exceptional on-road compliance makes this the top-end choice for serious builds
Torque GT take: Spoon springs hit the sweet spot for daily drivers. For track builds go coilovers and you will not look back.
Anti-Roll Bars
Spoon's adjustable front and rear anti-roll bar set is one of the most cost-effective handling upgrades available for the FL5. Uprated bars reduce body roll and sharpen cornering response with a quick installation and the improvement in stability through fast corners is immediately noticeable. A strong option for owners who want better handling balance without committing to a full coilover setup.
3. Lightweight Wheels
The FL5 runs large-diameter factory wheels which carry significant rotating mass. Moving to a quality lightweight aftermarket wheel reduces unsprung weight and allows the suspension to react faster and more accurately to road inputs.
| Wheel | Best For | Construction | Price Point |
|---|---|---|---|
| ENKEI NT03RR | Fast road and track | MAT flow-formed | ££ |
| ENKEI RS05RR | Fast road and track | MAT flow-formed | ££ |
| RAYS Volk Racing TE37 | Serious performance builds | Full forged | £££ |
| Spoon SW388 | Fast road and track | Full forged | £££ |
-
ENKEI NT03RR — a step up from the RPF1 with a more aggressive multi-spoke design. Equally lightweight with a more distinctive appearance and plenty of size options
- ENKEI RS05RR — a premium choice from Enkei, features a 15-fin spoke design with an aggressive concave face providing super aggressive look
- RAYS Volk Racing TE37 — fully forged and the benchmark lightweight wheel for serious FL5 builds. A meaningful step up in weight reduction over flow-formed options with the motorsport pedigree to match
- Spoon SW388 — Iconic design and distinctive motorsport styling. A strong choice for FL5s that are going for a Spoon inspired build.
4. Intake Upgrades
The turbocharged K20C1 responds well to improved airflow with sharper throttle response and a more distinctive induction sound at full boost. Options range from a simple drop-in panel filter to a full enclosed carbon system depending on how far the build is going.
| Intake | Best For | Construction | Install | Price Point |
|---|---|---|---|---|
| Spoon Sports Panel Filter | OEM+ and daily use | Drop-in replacement | Simple | £ |
| Eventuri Carbon Intake | Maximum performance and aesthetics | Full enclosed carbon | Professional recommended | ££££ |
- Spoon Sports Panel Filter — the OEM+ recommendation. A direct drop-in that improves airflow while keeping the engine bay factory clean, no fitment or tuning requirements needed.
- Eventuri Carbon Intake — the benchmark FL5 intake. Fully enclosed carbon housing with dyno-proven performance gains and the most aggressive induction sound available for the platform. Requires professional install and tuning.
Torque GT take: The Spoon setup is the ideal hassle-free OEM+ option. For maximum performance and the best engine bay presentation the Eventuri is the gold standard on the FL5.
5. Exhaust Upgrades
The FL5 exhaust note from the factory leaves real room for improvement under hard acceleration. An upgraded system reduces back pressure and gives the K20C1 the sound it deserves at full boost without making the car antisocial on a daily commute.
| Exhaust | Best For | Construction | Character | Price Point |
|---|---|---|---|---|
| HKS Legamax Premium | Fast road and track | Stainless with titanium tips | Aggressive and refined | £££ |
| Spoon Sports N1 | OEM+ and track | 70mm stainless | Iconic Spoon character | ££££ |
| Fujitsubo A-RM+C Titanium | Ultimate build | Full titanium with carbon exits | Premium JDM tone | £££ |
- HKS Legamax Premium — twin-exit stainless steel system achieving up to 30% reduction in back pressure with burnt titanium tips. Smooth turbo response and strong build quality at a more accessible price than the top-end titanium options
- Spoon Sports N1 — track-focused but street refined. A 70mm stainless design optimised for flow and the iconic Spoon exhaust character that Honda enthusiasts know well
- Fujitsubo A-RM+C Titanium — the premium choice for the FL5. Full titanium construction with carbon twin exits and a metallic JDM exhaust note that is in a class of its own
Torque GT take: Fujitsubo sets the bar for sound and quality on the FL5. The HKS Legamax is the best accessible option for owners who want a meaningful upgrade without reaching the top-end budget.
6. Cooling Upgrades
Heat management is a known consideration on the FL5 when pushed hard at circuits. When coolant temperatures climb beyond the ECU threshold power is cut to protect the engine which on a track day means losing performance at exactly the wrong moment. The right cooling upgrade addresses this before it becomes a problem.
- Spoon Low Temp Thermostat — opens at 68°C versus the OEM 78°C to keep temperatures stable during prolonged hard driving and prevent ECU-triggered power cuts. One of the most effective and affordable track upgrades on the FL5 and a non-negotiable addition to any car attending circuits regularly
Torque GT take: The Spoon thermostat is a simple and proven solution trusted by our sponsored Time Attack drivers. If your FL5 is seeing track use it should already be fitted.
7. Shifter Upgrades
Honda got the FL5 gearshift largely right from the factory but Hybrid Racing components sharpen it further. Options range from budget-friendly individual upgrades with a noticeable impact on feel to a combination of all three for the most precise gearchange the FL5 platform allows.
- Hybrid Racing Detent Springs — increases selector tension for crisper more defined shifts. A small modification with a bigger impact on feel than the price suggests.
- Hybrid Racing Shifter Base Bushings — replaces the soft OEM rubber bushings that cause vagueness in the shift action. Eliminates slack and pairs well with the detent springs as a budget-friendly combined upgrade
- Hybrid Racing Shifter Cable Bushes — competition-grade bushings that eliminate deflection and cable stretch in the shift cables for a more direct and mechanical feel at the gearbox. The final piece in a complete Hybrid Racing shifter setup
Torque GT take: Combine all three Hybrid Racing components for the most significant improvement in FL5 shift precision and driver feedback. Each part is affordable individually but the combined effect is well beyond what the individual price tags suggest.
8. Styling and Interior Upgrades
The FL5 already looks purposeful straight from the factory. The right styling upgrades from Mugen and Spoon sharpen both the exterior and interior without compromising the car's character, with small deliberate details from the right brands making a bigger statement than anything bolt-on.
- Mugen Front Bumper Garnish and Under Spoiler Lip — the most significant visual change you can make to the FL5 exterior. A race-inspired front end transformation with Mugen build quality and precise factory-level fitment
- Mugen Wind Deflectors — OEM-level fitment with subtle Mugen branding. Allows windows to be cracked without wind noise or rain ingress and is a practical daily upgrade
- Spoon Mirror Glass — blue-tinted convex mirrors that improve rear visibility and reduce glare with a small Spoon logo adding a tasteful JDM detail to the exterior
- Aftermarket steering wheels — high-quality materials, smaller diameter, instantly changes the driving feel. Spoon switch bracket means you can retain factory steering wheel buttons
Engine Bay Styling
Spoon and Fujitsubo engine bay components are the benchmark for FL5 owners who care as much about what is under the bonnet as what is outside it.
- Spoon Engine Bay Styling — carbon plug cover, coloured rocker cover and billet oil filler cap. The full Spoon engine bay setup is the definitive OEM+ look for any FL5 build
- Fujitsubo Titanium Bonnet Stay — lightweight burnt titanium finish replacing the factory stay. A standout detail for show builds and concours presentations
