pairs a Heavy Duty pressure plate with a Performance Street Sprung disc to give the BMW N52 platform stronger clamp load and better pedal feel than the factory clutch while still staying streetable for daily driving. Advanced Clutch Technology (ACT) has engineered performance clutch systems in the United States since 1988. Every ACT kit is designed, tested, and assembled in house, pairing heat resistant friction materials with.
Key Features
- Heavy Duty pressure plate increases clamp load up to 60 percent over stock for reduced slippage
- Performance Street Sprung disc uses a sprung hub and organic friction material for smooth engagement
- Kevlar lined friction material resists heat and wear far better than a stock disc
- Balanced and dyno tested assembly for smooth, consistent engagement at the pedal
- Direct bolt in fit using the factory pressure plate bolt pattern, no drilling required
- Exact ACT manufacturer part number BM15-HDSS for confident product matching

Frequently Asked Questions
What is ACT part BM15-HDSS?
It is the clutch kits - single described on this page in the exact listed configuration.
How do I confirm fitment?
Match the exact MPN plus year, make, model, trim, engine, transmission, drivetrain, and every application note.
Can I choose a clutch component by vehicle alone?
No. Clutch diameter, input-shaft spline, flywheel step, release system, engine code, and transmission can vary within one vehicle listing.
What is included?
Only the ACT components and quantity identified by this exact title and MPN are included. Related hardware or drivetrain parts may be separate.
Is break-in required?
Follow the current ACT instructions for the exact friction material and kit. Street clutch assemblies commonly require a controlled break-in period before full-load use.
Is professional installation recommended?
Yes. Clutch and flywheel work requires transmission removal, correct fastener procedures, alignment, release-system setup, and final operational checks.
Is this product new?
Yes. The item condition is new unless the product page explicitly states otherwise.
What should I verify before checkout?
Confirm the MPN, application, torque requirement, friction material, spline and diameter, flywheel compatibility, included items, and required hardware.
Installation Instructions
- Confirm ACT part BM15-HDSS and the complete engine, transmission, flywheel, spline, and release-system application before disassembly.
- Inspect every component and compare the new part with the removed assembly before modifying or installing anything.
- Inspect the flywheel or friction surface, pilot support, release bearing, fork, pivot, hydraulic system, seals, and mounting hardware.
- Clean friction surfaces correctly and keep oil, grease, and fingerprints away from the clutch disc and mating faces.
- Use the vehicle service procedure and current ACT instructions for alignment, fasteners, torque sequence, release travel, and clearances.
- Verify smooth release, correct free play, clean gear engagement, and leak-free operation before road use.
- Complete the manufacturer-specified break-in procedure before launches, dyno pulls, racing, towing, or full-torque operation.
