TRQ Rear Brake Rotors Set Vented Compatible with 2001-2006 BMW 330Ci

In this review the TRQ Rear Brake Rotors Set is evaluated as a straightforward, vehicle-specific replacement for older BMW 3 Series models. The bottom line: these rotors are for owners who need a direct fit OE replacement with predictable braking performance and uncomplicated installation. Fitment covers 2001-06 330Ci and 2001-05 330i and 330xi rear driver and passenger sides, and the kit includes both rear rotors so you can replace the axle at once.

Key Features

• Direct Fit: Designed as an OE replacement so the rotors mount without modification and match factory dimensions for a straightforward swap.
• Complete 2-Piece Kit: The package includes both rear driver and passenger side rotors, allowing simultaneous axle replacement and balanced braking performance.
• Vehicle Specific Fitment: Fitment information is vehicle specific, reducing guesswork for compatibility with 2001-06 330Ci and 2001-05 330i/330xi rear applications.
• Cast Iron Construction: The rotors are cast iron, providing the mass and thermal capacity expected of conventional replacement rotors for consistent stopping feel.
• Measured Dimensions: Key dimensions such as outside diameter, thickness, and center hole diameter match factory values to retain wheel and hub alignment.
• Aftermarket Reference: Identified by aftermarket reference number 980126, making cross-referencing with service parts catalogs easier.

Who It's For

This set is best for DIY enthusiasts and independent shops working on BMW E46 models who want a direct replacement without machining or guesswork. Because it ships as a pair, it is also suited to owners replacing both rear rotors to restore even braking and pedal feel.

Those who demand premium coatings for long-term corrosion protection or slotted/drilled performance rotors should look elsewhere, but for a stock-style replacement that restores factory dimensions and braking smoothness, these rotors are an appropriate choice.

Pros & Cons

Pros

• Good fitment for covered BMW rear applications, making installation straightforward.
• Restores smooth braking feel and stopping power when replacing worn or warped rotors.
• Cost-effective pair kit that provides value for an axle-level service.
• Solid cast iron construction that matches conventional rotor expectations.

Cons

• Coating quality receives mixed feedback and some users report surface rust forming quickly in wet conditions.
• Not a performance rotor option - no slotted or drilled surfaces for aggressive cooling or styling.

Our Verdict

The TRQ Rear Brake Rotors Set is a practical OE-style replacement for 2001-06 330Ci and 2001-05 330i/330xi rear applications, offering reliable fit and smooth braking at a reasonable price.

Frequently Asked Questions

Does this kit include both rear rotors?
Yes, the kit includes one rear driver side rotor and one rear passenger side rotor so the entire rear axle can be serviced.

Will these rotors fit my BMW E46?
They are listed for 2001-06 330Ci and 2001-05 330i and 330xi rear applications; check vehicle-specific fitment information in the listing to confirm compatibility.

Are these rotors coated to resist rust?
They have a surface coating, but customer reports note mixed coating performance and some rapid rusting in wet conditions, so expect typical cast iron aging in corrosive environments.
