BMW i4 Parts & Accessories

Shop BMW i4 parts and accessories for suspension projects, brake maintenance and everyday interior care at Black Ops Auto Works. Compare H&R and AST spring applications, applicable brake-service components, Kagu mats and wheel hardware. Select parts for your exact i4 version and factory equipment.

H&R and AST Suspension Choices

Choose a lowering package around the stance you want and the suspension fitted to your i4. H&R 28588-2 serves its specified eDrive35/eDrive40 rear-air application, while 28588-1 covers its specified M50 rear-air applications, including adaptive suspension. AST lists separate 25, 30, 35 and 40 mm nominal-drop options, with drop links identified on the 40 mm package. Compare the exact reference, supplied components and clearance plan before choosing a setup; stated lowering is a guide for the supported application, not a guaranteed final measurement.

Brake Pads, Rotors and Service Hardware

Brembo PRIME, DFC and PowerStop replacement options support different brake-service plans, while EBC lists distinct daily-driving and performance compounds for its qualified applications. Match the caliper, axle and disc specification first, then choose the compound for how you use the car. Inspect disc condition and compare sensor and hardware contents before deciding between pads alone and a wider axle refresh.

Kagu Mats and Wheel Accessories

The L1BM12921509 Kagu liner provides second-row protection for its listed i4 application and explicitly excludes M50 and xDrive. Its waterproof surface and raised edges offer practical rear-cabin coverage where that exact application matches. For a wheel project, compare Dinan spacer pairs by measured clearance and choose the correct longer bolts separately; McGard locks need to match the complete wheel mounting arrangement.

Frequently Asked Questions

Are the listed i4 spring applications interchangeable?

No. H&R distinguishes eDrive35/eDrive40 rear-air-suspension applications from M50 adaptive-suspension applications. Review each exact reference.

How do I choose between the AST lowering amounts?

Compare the nominal drop with your current height, driveway access and tire-to-body clearance. Review the exact kit’s vehicle coverage and contents with the installer, including any drop links, then plan alignment and final setup rather than choosing solely by the largest drop.

Which brake-pad compound should I choose?

First establish exact brake-package coverage, then select a compound intended for your driving and service needs.

Does the listed Kagu rear liner fit M50 or xDrive?

No. L1BM12921509 excludes M50 and xDrive in its detailed application. It covers the second row for its specified i4 versions, so it is also separate from front-row protection.

Are longer bolts included with the Dinan spacer pairs?

Appropriate longer bolts are selected separately for the listed spacer installation. Match wheel-seat design, thread and usable engagement to the complete wheel-and-spacer combination, then compare package quantities with the wheel positions being changed.
