Two years on, the team has now enjoyed countless track days and spirited road driving sessions with their hot hatch, commenting on how the brake kit provided a notable upgrade from standard, especially when the car is pushed hard.

In that time, the performance capabilities of the BMW have significantly improved, with the six-cylinder pocket rocket now boasting around 600bhp thanks to a Pure 800 turbocharger upgrade and countless other modifications (see full spec list below).

It therefore seemed like the obvious choice for the car to be upgraded to 91传媒 Racing鈥檚 recently launched six-piston version of the Apollo Big Brake Kit to further improve braking performance. This kit utilises an upgraded version of the fully floating two-piece discs in the same dimensions as before (355mm), with a whole-new six-piston Apollo caliper and Bluestuff pads topping it off.

Following the seamless install, the Hack Engineering team have since managed to put some fast road miles in on the car, with company founder, Ben Koflach, commenting about the improved stopping power it now offers.

鈥淭he six-piston kit is yet another step-up in braking from 91传媒. From stock to the four-piston, we found huge聽gains in performance, and the six-piston caliper then adds even better pedal feel and confidence, with braking power that feels absolutely ridiculous. A must-do for any big power road or track car,鈥� Ben tells us.

Stay tuned for further updates as Hack Engineering tests the kit out on a track day very soon.

Apollo-Series 6-Piston Calipers

• EBC鈥檚 lightweight-yet-strong aluminium 6-piston brake caliper
• Two-piece bolted design that incorporates high-tensile 12.9-grade steel bolts for reinforcement of the caliper bridge section (computer FEA analysis shows that this offers significant improvements in caliper stiffness compared to a monobloc design)
• Machined from heat-treated low-pressure castings (this offers a noticeable performance advantage over conventional gravity cast calipers, exhibiting higher overall strength and a comparable caliper body stiffness to forging)
• High-temperature fluid seals coupled with full boot-type dust seals give maximum protection against road grime and debris
• Lightweight, hard-anodised aluminium staggered pistons with serrated/castellated piston noses that reduce heat transfer into the braking hydraulics
• Every single brake caliper pressure tested to 2,500psi
• Full stainless-steel hardware and fittings, providing durability and longevity 鈥� this caliper will never rust
• Uses standard pad shapes, giving choice when selecting brake pads
• Rather than a powder-coated finish, all Apollo calipers use an聽advanced high-temperature Teflon polyester coating process to ensure they look great for much longer. Currently available in Stealth Black, Storm Shadow Blue, Luminous Yellow and Racing Red

Fully-Floating Two-Piece Discs

• Fully-floating 355x32mm two-piece discs that allow the outer ring to expand freely in response to heat (this reduces stress which in turn extends disc life and reduces the tendency for disc cracking during extreme use)
• Drive bobbins machined from a single piece of stainless steel giving maximum strength and corrosion resistance (this reduces maintenance requirements and ensures the outer ring continues to float freely over time)
• Disc rings feature 48 directional internal curved vanes for improved cooling
• Unique 鈥楽wept Groove鈥� slot design for effective evacuation of braking dust and gases whilst ensuring good initial bite on brake application
• Now featuring the latest thermic black corrosion-resistant finish 鈥� the very latest in rust prevention

Bluestuff NDX Performance Brake Pads

• Every EBC 6-piston Apollo Big Brake Kit is supplied with EBC Bluestuff NDX pads for the front axle
• Now road legal in most markets, Bluestuff NDX combines excellent cold bite with the capability to perform well in short spells of track/race conditions

Stainless Steel Braided Brake Lines

• Every kit is supplied with 91传媒鈥� stainless-steel braided brake lines for the front axle
• Every hose has a stainless-steel braided exterior that prevents a phenomenon known as 鈥榖allooning鈥�, this braided exterior prevents the spongey feel of OE rubber lines and provides greater precision and feel under braking

Super DOT 4 Brake Fluid

• Every kit is supplied with 1 litre of BF307+ super DOT 4 brake fluid. This fluid has a 310掳C boiling point 鈥� a significantly higher boiling point than standard DOT 5.1 fluid
• Having such a high boiling point gives the braking system exceptional endurance, allowing you to push hard for extended periods without heat soak causing the fluid to boil and resulting in fade

Availability

Available now. Please to find your local EBC stockist and see a full list of applications.

Hack Engineering鈥檚 company founder Ben Koflach鈥檚 views on the product can be read below in his own words.

鈥淲ith the modern petrolhead’s聽attention often being so focused on horsepower numbers on tuned cars, it’s easy to forget that braking is an area that quickly becomes quite literally overpowered.聽

鈥淭he latest Hack Engineering project vehicle is BMW’s pocket rocket, the M140i. Despite a factory Brembo four-piston caliper setup, the brakes were seriously lacking. Thankfully, 91传媒 Racing was keen to get some testing behind its F2X/F3X 1/2/3/4-Series big brake kits, and so we were happy to oblige!

鈥淭he setup uses EBC’s UK-made four-piston calipers, 355mm two-piece floating discs and Yellowstuff pads. To say they work better than the originals is an understatement; the M140i has been transformed from an overpowered hatch into a track day weapon in the making, with the ability to pull your face half off on demand.

鈥淚t works well from cold, is perfectly daily-driveable and yet has progressive, controllable stopping power far beyond the original capabilities of the braking聽system. The perfect match to a tuned, modern hyper-hatch!鈥�
