ST Big Brake Kits - StopTech C43 Front Race BBK for Honda S2000 (Part: 87.429.D900.R7)

If you are tracking your AP1 or AP2 and keep running into a mushy brake pedal or cracking your front rotors after a couple of hard hot laps, upgrading to this ST Big Brake Kits front race assembly is the definitive fix. This dedicated front setup features StopTech’s forged C43 motorsport calipers paired with heavy-duty 309x32mm 2-piece bi-slotted AeroRotors. It is engineered purely for wheel-to-wheel racing and intensive track abuse, giving you massive thermal capacity without adding a bunch of heavy unsprung weight to your front spindles.Unlike generic street big brake upgrades, this specific ST Big Brake Kits package uses a hard, natural clear anodized finish on the calipers instead of standard paint or powder coating. This means they can handle extreme track temperatures without blistering or turning an ugly brown color. The 2-piece floating AeroRotors utilize specialized race floating pin hardware. This allows the outer friction ring to expand independently when dealing with intense heat cycles, completely eliminating the rotor warping and pedal pulsation that usually ruins an S2000's braking performance on the track.

Features and Benefits

  • Stiff Forged C43 Calipers: Features an ultra-rigid, 4-piston forged aluminum body optimized specifically for racing environments. This gives you instant pedal response and drops caliper flex down to basically zero under heavy braking.
  • 309x32mm Bi-Slotted AeroRotors: The internal curved vane design pumps significantly more cooling airflow through the rotor compared to stock styles. The bi-slotted face continuously clears out pad off-gassing and track debris without cracking risks.
  • Full-Floating Race Hardware: Equipped with full-floating drive pins that allow the rotor hat and ring to move independently, which completely stops pad knockback when you are hopping over aggressive track curbing or loading up in high-G turns.
  • Raw Anodized Finish: The natural clear anodized surface treatment is built explicitly for harsh heat management, so it won’t peel, bubble, or fade like aesthetic street finishes when things get hot.
  • Complete Track Package: Arrives ready to bolt up with high-stiffness caliper mounting brackets, stainless steel braided lines, race-specific brake pads, and all the necessary installation hardware.

Vehicle Fitment

Double-check your chassis setup before ordering. This ST Big Brake Kits front configuration is built explicitly for:
  • Model Years: 2000, 2001, 2002, 2003, 2004, 2005
  • Chassis: Honda S2000 (AP1 and early AP2 platforms).
  • Placement: Front axle setup only.
  • Wheel Clearance Note: Because of the wide 4-piston C43 caliper profile and the thick 32mm race rotors, stock factory wheels will not clear this kit. You will need high-clearance 17-inch aftermarket track wheels or specific wheel spacers to clear the spokes.

FAQ

Does this ST Big Brake Kits assembly come with street or track pads?
This specific package (87.429.D900.R7) is classified as a dedicated track system, so it comes out of the box with StopTech’s aggressive race-compound pads. They need adequate heat to actually friction properly and will squeal and eat rotors if you try to use them for cold street driving.
Why are these calipers anodized instead of painted or powder-coated?
Painted finishes look nice on street cars, but they burn up and peel off quickly under continuous racing heat. The natural clear anodized finish handles extreme thermal cycles effortlessly without degrading structurally or looking ruined after one weekend.
Will my factory 16-inch or 17-inch S2000 wheels fit over this kit?
No, they won't. The stock Honda wheels don't have enough internal spoke clearance to bypass the wide C43 calipers without heavy contact. You will need to check your wheel setup against a physical clearance template, as most track builds require high-clearance 17-inch aftermarket racing wheels.
