E46 is five body styles and two front axles
Key takeaways
- Five bodies, one code: sedan, Touring, coupe, convertible and compact all carry E46, and the M3 version was built in coupe and convertible bodies only.
- Two windows and one facelift: the range ran from December 1997 to November 2006, the sedan and Touring were facelifted in September 2001, and the M3 ran from September 2000 to August 2006.
- The rows start at 18 inch: 345 mm or 355 mm at 18 inch, 355 mm or 380 mm at 19 inch and 380 mm at 20 to 21 inch are planning references.
- Eight fields and a price line need a decision: Sold As reads Left only, the install fields promise a replacement with no extra work, market and setup read left-side market and standard factory, MOQ reads 1 unit, three commercial fields are placeholders, the page summary still carries a template line, and a struck-through USD 688.00 figure sits beside the ladder.
If you searched for BMW E46 front brake caliper kit, the car you are holding could be any of five body styles, could be a pre-facelift or facelift build, and could be an M3 or a 330i with a different front axle underneath. This page settles which car it is before it names a bracket.
What the kit needs to know about your car
A fixed six-piston body is wide, and the factory caliper on most E46 cars is the sliding type that moves sideways instead. So the file starts with the car, not with the wheel.
What the car is now
Twenty-year-old cars do not always match their build sheet. A September 2026 owner thread describes a pre-facelift E46 that left the factory as a 328i and now runs a 330i engine, and the buyer’s first question is what else moved with it. Send the VIN, the build date and photographs of the front corner so the record describes the car as it stands, not as it was sold.
Where the badge stops helping
The market splits its E46 kits the same way this file does. One maker titles its front kit E46 (non-M), another lists an M3 E46 kit and a 3 Series E46 kit as separate products, and a third lists its front kit for the 330i and 330Ci only. A badge on the boot lid is a starting rule, not a brake specification.
Scope of this page
Front axle only. The rear axle sits outside this set: it is quoted as its own file, and the rear caliper type and rotor interface are confirmed before that file opens.
Records that decide the bracket year
Eight control lines decide the bracket and the rotor row. Six come from the car, two from the wheel and the suspension.
| Control field | On the record now | Send with the request |
|---|---|---|
| Body style and build date | No year band is published as an approval | the body style, the build date and the VIN, sent privately |
| M3 or non-M3 | The two front axles are separate records | the VIN with photographs of the front caliper and the rotor face |
| Facelift side | The sedan and Touring changed in September 2001 | whether the car is before or after that change |
| Engine and brake history | A later swap is recorded rather than assumed away | what has been changed, with receipts where they exist |
| Wheel size and status | 18, 19 and 20 to 21 inch rows are planning references | the wheel size plus original or aftermarket status |
| Aftermarket ET and J | Not supplied until the wheel is known | the ET and J values from the wheel itself |
| Spoke and inner barrel | Not supplied until the wheel is known | photographs of the spoke back and the inner barrel |
| Ride height and suspension | Not supplied until the car is described | springs, coilovers, spacers and any extended ball joints |
Original wheels are checked against our own record file using the year and the VIN, so ET and J are not requested in that case. On an aftermarket wheel, ET sets where the mounting face sits relative to the wheel centre line and J sets the rim width, and both change the space a six-piston body has to live in. A ball joint that moves the hub changes that space as well.
Rotor rows for 18 to 21 inch wheels
Planning reference only. A diameter suggests a row rather than approving one, and no row here covers a 16 or 17 inch wheel.
| Wheel reference | Rotor planning reference | Measure before release |
|---|---|---|
| 18 inch | 345 mm or 355 mm | Spoke clearance, inner barrel, ride height and the approved caliper template |
| 19 inch | 355 mm or 380 mm | Wheel geometry, rotor interface and the bracket position |
| 20 to 21 inch | 380 mm | Wheel construction, tyre package, rotor offset and hose movement |
Owners meet the same problem from below. A 2026-09-20 thread from a pre-facelift 330ci owner who wanted 16 inch winter wheels reported that owners treat 17 inch as the practical floor because of brake size, and this kit’s first row is 18 inch, so a car still on factory-size wheels has to change its wheel plan before it can use any row here. The market’s own numbers sit where you would expect: the factory-caliper route is quoted at 325 x 25 mm on E46 330-sized rotors and the big-brake route at 355 x 32 mm, which is the same diameter family as the 18 inch row.
Two shortcuts that cost money
- Reading the badge as the axle. M3 and non-M3 E46 cars do not share a front axle, and the market sells them as separate products for that reason.
- Changing suspension after the wheel file. One vendor states its E46 brake kits may not suit aftermarket suspension such as extended ball joints, and that kits cannot be returned for fitment reasons, so a suspension change belongs in the file before the quotation.
Rotor runout – the wobble read on the hub – is checked before the wheels go back on, and clearance stays a measurement rather than a table lookup.
What ships for one front axle
One order is a matched front package: 2 calipers, 2 brackets, 2 rotors, 4 pads and 2 hoses for the front axle, with the quantities fixed before the quotation leaves.
| Component | Quantity | Interface still to check |
|---|---|---|
| Calipers | 2 V6 six-piston bodies | Mounting ear position and the approved bracket |
| Adapter brackets | 2, machined per vehicle | Bracket offset and rotor centre line |
| Brake rotors | 2 | Diameter against the wheel envelope and the hub interface |
| Brake pads | 4 | Pad shape and compound against the supplied body |
| Brake hoses | 2 | Fitting type, routing across steering travel and suspension movement |
Installation
The bracket is machined to the car and sets where the caliper sits on the hub, so installation is confirmed before the order is released and this page does not promise that the set drops onto an unmeasured car. A qualified technician completes the work with the car on the ground.
A calipers-only order is a different configuration. It leaves the rotor, bracket, pad and hose interfaces on your side of the table, and the rows above stay out of play until that combination has been checked. The rear axle is a second file as well, so a two-axle order lists 4 calipers and 4 rotors across the two records. Export packing is listed at 45 x 45 x 45 cm and 45 kg on the current record, and both numbers get rechecked against the final rotor size before dispatch.
Material lines, and the approvals that do not exist
Three material lines are on file, and they are the whole record:
- Caliper body, hat and adapter bracket: 7050 aluminium alloy.
- Brake rotors: high-carbon cast iron.
- Brake pads: ceramic friction material.
No grade sheet, no test report and no approval file sits behind those lines, so a buyer cannot quote a material grade, a process route, a road-legality status or a performance figure from this page. The photographs show bodies and cartons carrying lettering that is not ours; the lettering is a finish on the part and packaging around it, and this page claims no licence, sponsorship or authorisation over any mark it does not own.
The V6 label is the series name this record is sold under. The live page also prints cells that talk about a brief and about a series reference supplied by the buyer; that wording is on the correction list rather than in the copy.
Where these kits go, and what they cost
Importers, distributors and workshops
These buyers usually start with one set, prove it on a local car and commit to a stocking order afterwards. That buyer’s file carries the same bracket and rotor data as a retail order, and it adds two more fields, the destination country and the quantity, so freight and paperwork travel in one quotation.
Owners, track builds and repair shops
Much of this demand is track-adjacent. A 2003 E46 M3 race car in this month’s owner threads runs StopTech big brakes with JRZ coilovers, and a beginner bought a 2004 325Ci for track days. Cars like those already carry a modified brake file, so this record describes what is on the car instead of inheriting it.
MOQ is 1 set, and the order opens with a 30% deposit. Production takes 3–7 business days, the delivery window that follows is about 20–35 business days, and the balance settles before dispatch. Wear parts, installation errors and unauthorised changes are not covered, while the defect warranty runs 5 years. The ladder reads USD 448 per set for 1–9 sets, USD 380 for 10–49 and USD 350 for 50–199, and the save notes follow the 448 figure. The 688 figure printed struck through beside the unit price sits on the correction list, because it cannot be reconciled with the rest of the block.
Six questions from E46 owners
Does this kit fit every E46?
No. Sedan, Touring, coupe, convertible and compact bodies all carry the E46 code, and the M3 version was built in coupe and convertible bodies only with its own front axle. The body, the build date and the VIN go on the record before a bracket is named.
How does a buyer prove the car is an M3 rather than a modified E46?
The VIN and the build record settle it, and the market splits its kits the same way: one maker titles a kit E46 (non-M), another sells an M3 kit and a 3 Series kit separately. Owners also swap engines on this generation, so what the car is now is written down as well.
Will 18 inch wheels clear the 345 or 355 mm row?
Those two diameters are the 18 inch planning pair. Spoke shape, offset, inner barrel, ride height and the approved caliper template still decide, which is why photographs travel with the measurements.
Why can an aftermarket suspension stop a brake kit from fitting?
Because it moves the hub. One vendor states that its E46 brake kits may not suit aftermarket suspension such as extended ball joints, and that kits cannot be returned for fitment reasons, so springs, coilovers and ball joints belong in the file before the quotation.
What happens to the rotor and hose interfaces on a calipers-only order?
They move to your side of the review. Calipers-only is a separate configuration, and the rotor rows on this page stop applying until the rotor, bracket, pad and hose combination has been checked.
Two numbers appear in the price block, so which one is the current price?
The published ladder is USD 448 per set for 1-9 sets, USD 380 for 10-49 and USD 350 for 50-199. That 688 figure sits on the correction list until the business confirms or deletes it.
The photographs, and the file we open next
Three photographs sit below: the pair laid out on its boxes with the bracket across the bench, one body clamped over its rotor, and a finished body on a display stand. They show the kit, the pairing marks and the finish, so they cannot stand in for a measurement on your car.
Our fitment desk maintains this file, and it was last reviewed on 2026-09-24. Sources checked: the 3 Series E46 record for the body styles, the production window and the September 2001 facelift, and the M3 record for the M3 production dates and body styles. Both sources describe the model history only. Neither one approves a bracket, a rotor row or a wheel for a specific car.
To open a file, send the body style and the build date, the VIN privately, the market the car was sold in, the engine and brake work that has been done, photographs of the front calipers and the rotor face, the rotor diameter and thickness, the wheel size with original or aftermarket status, ET and J values for aftermarket wheels, and the ride height with springs, coilovers, spacers or extended ball joints already fitted, plus the destination country and the quantity. Our reply carries the approved bracket and rotor row, the production and delivery windows, and the price of the set.
