PRODUCT DETAILS
RallySport Direct carries a massive selection of high-performance braking components brought to you by the industry leaders at Stoptech.
Here, you are looking at the Stoptech ST-40 Big Brake Kit. This is a kit that features large 4-piston calipers that are combined with either slotted or cross-drilled rotors that will increase the overall braking capacity of your vehicle. This brake kit will exceed the limits of your OEM brakes by allowing the driver to brake harder with the reduced chance of brake fade, and the included stainless steel brake lines will provide a consistent pedal feel with reduced system compliance.
DETAILS:
- Front location
- Red caliper finish
- Calipers feature a durable and lightweight aluminum construction
- 2-piece zinc slotted rotor design
- Slotted rotors expel hot gasses, brake dust, and residue from the contact surface to allow for more efficient and cooler braking operation
- 332mm rotor size
- Stainless steel brake lines won't expand under pressure to deliver a consistent and direct pedal feel
INCLUDES:
- (2) ST40 brake calipers
- (2) Zinc slotted rotors
- (2) Caliper adapter brackets
- Stainless steel brake lines
- Stoptech high-performance brake pads
NOTE:
- Because these are larger calipers, aftermarket wheels are required for clearance in some cases. Please contact our customer support team for a wheel fitment guide
WHY WE CARRY THIS
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
