Build Your Big Brake Kit
Build a front kit, or a complete front + rear big brake kit on iron / steel rotors. Pick the caliper, rotor and pads — the price updates live. We confirm the exact fitment for your wheels before production.
Wheel size
Start here — pick your wheel diameter and we’ll grey out the calipers and rotor sizes that won’t clear it. Optional — we always confirm exact fitment before production.
Caliper source
Our house calipers — exact price, ready to build.
Caliperprice per pair
Match the piston count to rotor size, wheel clearance and braking load.
Rotor size — 285 to 440 mm
We size the disc to your wheels (15″+) and driving style. Non-standard sizes — like 394, 398 or 402 mm — are made to order, just get in touch.
Rotor construction
Thickness
Rotor face pattern
Every face pattern is machined to the same price — choose on looks and on how the car is driven. Hat is 7075-T6, black anodized as standard — color can be customized upon request.
Anti-rust ring coating
Keeps the hat, vanes and edges free of surface rust. On the braking contact area the coating gradually fades as the pads bed in — that is normal and standard for this finish.
Caliper color & logo
Brake pads
Street is quiet and low-dust; light track mixes street & track use; race is for full-heat sessions.
Forged wheel spacers & adapters — optional
Clear a wider caliper, fill the arch, or run wheels your hub was never drilled for. Priced per axle for a pair — all bolts and nuts included.
Final kit price · front axle
Kit price for a pair. Standalone parts are priced higher.
Front axle
In-house production — CNC drilling an aftermarket caliper body, one of the machining stages behind every house caliper we build.
