Your i30 N or Kona N makes a strong case for enjoying the drive. This EBC Apollo kit gives its front brakes the same attention, using four-piston calipers and 355 mm fully floating discs for the applications below. It is a substantial brake conversion for a firmer, more responsive pedal, with road and competition configurations to suit different uses.
Kit reference: BBK015. Exact SKUs for every available configuration are listed below.
The reinforced caliper body helps resist flex under pressure, while the floating disc ring can expand separately as braking temperatures increase. That gives the upgrade a practical purpose when you are looking beyond the standard caliper and disc assembly. Choose around how you use your Hyundai and the exact wheel clearance, rather than treating Race competition as simply another finish.
The road calipers are designed, manufactured and assembled in the UK from heat-treated, low-pressure cast aluminium. Their two-piece bodies use grade 12.9 bridge bolts, with hard-anodised aluminium pistons, stainless-steel bleed nipples and wear plates. The material and construction put substance behind the appearance of the upgrade.
External dust boots keep road dirt and debris away from the pistons, with high-temperature EPDM fluid seals behind them. A hard-anodised body gives corrosion protection beneath the high-temperature colour coating, while the single pad-retention bolt allows quick pad changes when servicing is due.
This BBK015 offer uses 355 mm front discs and 4-piston calipers. Match the vehicle and original brake details below, then check the exact wheel-clearance template before selecting the caliper configuration.
Black, Blue, Red and Yellow are the painted road-caliper choices, with external dust boots and aluminium pistons. Choose the finish you want to see behind your wheels without changing the kit specification for that version.
Race competition is a different hardware and pad specification: hard-anodised calipers, stainless-steel castellated pistons and RP-X race pads. It is intended for dedicated track and race use, rather than chosen as another paint colour.
With the painted road configurations you receive:
The Race competition front brake assembly combines Apollo competition calipers, fully floating two-piece discs to the selected specification and RP-X race pads.

Match your vehicle, engine, year and any brake-package notes in the table. Disc measurements in this fitment table describe the original brakes; the new kit dimensions are listed under Technical specifications and in the SKU table.
Application years can vary by engine and kit option; check the detailed rows for your vehicle.

Have the kit fitted by a qualified brake specialist. The installation needs clean, sound mounting surfaces, the correct hardware and torques, proper bleeding, and clearance checks through steering and suspension movement. Dust-shield removal or modification can be part of fitting; keep any vehicle-specific instructions in the application table with the job.
The road kit is designed around the original master cylinder and rear brakes. If you have changed the master cylinder or rear brake arrangement separately, have your installer check compatibility and brake balance before ordering.
Follow the fitting instructions and the bedding procedure for the supplied pad compound before demanding full performance. When rear components are supplied, fit them as part of the intended brake upgrade. Inspect pad and disc condition regularly, especially during circuit use, and keep the hydraulic system in good condition.
It covers the N applications listed in the fitment table, with their engine, year and original brake conditions. Match those details together before choosing the caliper configuration.
Use the template for the exact kit version, printed at 100% scale, against the actual wheel. Wheel diameter alone does not establish spoke or caliper clearance. Send us your kit choice and wheel details if you need help arranging the check.
The friction ring can expand independently of its mounting bell as it heats up. That reduces thermal stress during repeated braking and is one of the engineering differences behind a fully floating two-piece kit.
You choose hard-anodised competition calipers, stainless-steel castellated pistons and RP-X race pads for dedicated circuit use. The painted road calipers use aluminium pistons and external dust boots. Use the exact SKU table to keep the chosen disc size and caliper configuration together.
A big brake conversion includes new front calipers as well as the discs and pads. The reinforced Apollo calipers and fully floating two-piece discs change the front brake assembly itself, with the matching kit specification and fitting requirements shown above.
