Is the Vehicle a BMW F34 Gran Turismo with the Correct Front-Brake Record?
This BMW F34 brake calipers page covers a GT6 front six-piston complete kit planned for 18-21 inch wheels. The F34 body code must be confirmed together with the exact year, trim, market and original front-brake package before a bracket or rotor path is released.
The F34 Gran Turismo body style should not inherit a bracket decision from a visually similar BMW 3 Series or from a related F30 or F32 enquiry. Body style, trim and installed front hardware form one fitment record. Wheel diameter is only the starting point for selecting the supplied rotor planning reference.
F34 approval sequence: confirm the Gran Turismo vehicle record and original front brakes, match the vehicle-specific bracket and rotor interface, then inspect the complete OEM or aftermarket wheel envelope. A similar BMW chassis does not prove interchangeable parts.
Four Fitment Checks Before Order
F34 identity
Provide exact production year, trim, market and VIN for private review. Do not use an F30 or F32 record as an automatic substitute.
Original front brakes
Record the installed front caliper, rotor and mounting information so the adapter bracket and rotor centerline can be checked.
Wheel status
State OEM / ORIGINAL WHEEL or AFTERMARKET WHEEL and provide the actual 18, 19, 20 or 21 inch wheel size.
Aftermarket geometry
For aftermarket wheels, provide ET and J values plus spoke and inner-barrel information where requested for clearance review.
Solution Summary – At a Glance
Target application
BMW F34 Gran Turismo subject to exact vehicle and original-front-brake approval.
Product
GT6 complete front package with two six-piston calipers.
Rotor planning
345, 355, 362, 380 and 405 mm references across 18-21 inch wheels.
Package scope
Calipers, adapter brackets, rotors, brake pads and hoses in the stated quantities.
Product Configuration Paths
| Configuration path | Current scope | Release condition |
|---|---|---|
| F34 standard front-brake record | Complete GT6 front six-piston kit for conditional review. | Approve exact vehicle data, original interfaces, rotor path and wheel clearance. |
| F34 performance or upgraded original brakes | Separate installed-hardware record under the F34 page scope. | Verify the actual caliper and rotor rather than relying on trim wording. |
| OEM wheel path | Use the exact original wheel specification with the selected rotor reference. | Template or physical clearance review remains required. |
| Aftermarket wheel path | Use wheel diameter, ET, J, spoke and inner-barrel information. | Approve the complete geometry with the planned caliper and rotor position. |
F34 enquiries should remain separate from F30 and F32 enquiries until the original front-brake record and vehicle-specific mounting information have been checked. Similar product photography or a shared wheel diameter is not enough to combine applications.
Configuration Specification Summary
| Item | Supplied information | Confirmation required |
|---|---|---|
| Product identity | GT6, as supplied in the product brief. | Use the page SKU and formal quotation for the approved seller description. |
| Caliper layout | Front axle, six pistons per caliper, two calipers. | Confirm approved bracket, pad and hydraulic interfaces. |
| Wheel range | 18-21 inch planning references. | Confirm wheel status, aftermarket ET/J and actual clearance. |
| Rotor plan | 18 inch: 345/355 mm; 19 inch: 362/380 mm; 20 inch: 380/405 mm; 21 inch: 405 mm. | Confirm remaining rotor dimensions and mounting interfaces. |
| Kit contents | 2 calipers, 2 brackets, 2 rotors, 4 pads and 2 hoses. | Match quotation and packing list to the page SKU. |
Wheel and Brake Disc Selection Matrix
Planning reference only. Wheel diameter does not confirm caliper clearance, and an F34 trim description does not confirm the installed front-brake package. Final approval requires the exact vehicle, original brakes, wheel status, aftermarket ET/J values, spoke shape, inner barrel and complete rotor interface.
| Wheel reference | Rotor planning reference | Checks before approval |
|---|---|---|
| 18 inch | 345 mm or 355 mm | F34 vehicle record, original brake interface, spoke clearance and inner barrel. |
| 19 inch | 362 mm or 380 mm | Actual wheel geometry, rotor interface and approved caliper template. |
| 20 inch | 380 mm or 405 mm | ET/J for aftermarket wheels, spoke profile, inner barrel and rotor position. |
| 21 inch | 405 mm | Complete wheel envelope, rotor interface, hose route and installation review. |
How Buyers Misapply the Matrix
Transferring an F30 or F32 bracket assumption
Related BMW model codes can appear interchangeable in a catalogue, but a bracket is controlled by the actual hub, original caliper mounting and rotor position. Keep the F34 record separate until the seller has reviewed the exact year, trim, market and original hardware.
Using wheel diameter as the only selection rule
An 18-inch wheel does not automatically accept 355 mm, and a 20-inch wheel does not automatically accept 405 mm. Rotor thickness, hat height, offset and mounting details must agree with the approved bracket and caliper position inside the actual wheel.
Risk note: incorrect year or trim information may result in a bracket that does not install. Unsuitable ET, J, spoke or inner-barrel geometry may leave insufficient caliper clearance.
Model and Specification Confirmation
| Control field | Current record | Order action |
|---|---|---|
| Page SKU | SLP-BMWF34-BC-GT6-6P-F-KIT | Keep this reference consistent across enquiry, quotation and packing record. |
| Vehicle identity | BMW F34 target family; exact vehicle not yet supplied. | Provide exact year, trim, market and VIN privately. |
| Original brakes | Installed package not yet supplied. | Provide original front caliper, rotor and mounting information. |
| Wheel specification | 18-21 inch planning range; wheel status not supplied. | State OEM or aftermarket and provide required geometry. |
| Rotor interface | Diameter options supplied; other dimensions not supplied. | Approve thickness, hat height, offset, center bore and mounting details. |
Material and Manufacturing Confirmation
Material grade, caliper construction, manufacturing process, finish system, rotor metallurgy, testing, certification and performance results were not supplied. Any such claim must come from the approved specification, drawing and formal quotation. This page does not infer forged construction, CNC production, racing certification, road legality or a guaranteed stopping-distance improvement.
GT6 remains the buyer-supplied product-series name rather than an SEO performance claim. Product markings, colors and labels must be checked against approved seller documentation before resale or installation. The requested Brembo wording is not used as a product identity because the current brief does not establish genuine Brembo manufacture.
Component Interface Engineering
| Component | Quantity | Interface review |
|---|---|---|
| Front six-piston caliper | 2 | Caliper position, rotor centerline, pad path and wheel clearance. |
| Adapter bracket | 2 | F34 original mounting points, approved fasteners and vehicle-specific position. |
| Brake rotor | 2 | Diameter plus thickness, hat height, offset, center bore and mounting data. |
| Brake pad | 4 | Pad shape and specification matched to supplied calipers and rotors. |
| Brake hose | 2 | Fitting type, routing, full steering travel and suspension movement. |
A qualified installer should review the approved installation information and verify fasteners, rotor runout, hose movement, wheel clearance and pedal operation. The component count defines the proposed package scope; it does not establish identical interfaces across every F34 year or trim.
Complete Matched Kit vs Calipers Only
Complete GT6 front kit
The current page covers calipers, brackets, rotors, pads and hoses under one F34 vehicle, original-brake and wheel approval record. This allows the main mechanical and hydraulic interfaces to be reviewed together before the formal quotation is released.
Calipers-only request
A calipers-only enquiry is a separate configuration. The buyer or workshop must control rotor, bracket, pad, hose and mounting compatibility. Do not transfer the 345-405 mm package assumptions into a calipers-only order without a new interface review.
Buyer and Supply Scenarios
Retail customer
Submit the exact F34 vehicle, brake and wheel record, then use a qualified workshop for installation.
Modification shop
Separate F34, F30 and F32 enquiries and verify the original brake package before scheduling work.
Distributor
Use the page SKU and approval record to prevent related BMW chassis enquiries from being mixed.
B2B buyer
Provide quantity, destination market and fitment data; use the formal quotation for commercial terms.
Procurement Specifics
| Procurement field | Current page information |
|---|---|
| Package contents | 2 calipers, 2 adapter brackets, 2 rotors, 4 brake pads and 2 brake hoses. |
| Carton size | 45 x 45 x 45 cm. |

The supplied carton size and gross weight are procurement references to be matched with the final packing list. They do not establish freight cost, shipping method, customs treatment or delivery time.
Common Fitment Questions
Is this kit automatically suitable for every BMW F34?
No. Exact year, trim, market, original front brakes, bracket interface and wheel clearance require approval before ordering.
Can an F30 or F32 bracket be used for the F34?
Do not assume that. Related chassis records must be kept separate until the actual F34 mounting and original-brake interfaces are approved.
Does an 18-inch wheel guarantee clearance for 345 or 355 mm rotors?
No. Spoke profile, inner barrel, width, offset, rotor interface and the approved caliper template still need review.
Should a 20-inch wheel use a 380 or 405 mm rotor?
Both are planning references. The approved vehicle, bracket, rotor interface and wheel envelope determine the final path.
What is required for an aftermarket wheel?
Provide wheel diameter, ET and J values, plus spoke and inner-barrel information where requested. A template or physical measurement may also be required.
Does the package include rear brake parts?
No. The supplied scope is a complete front six-piston kit. Rear calipers, rotors and parking-brake components are not listed.
What must be submitted before ordering?
Provide exact year, trim, market, VIN privately, original front brakes, wheel size and status, and aftermarket wheel geometry where applicable.
Documentation and Order Confirmation
Before production or shipment, match the enquiry and formal quotation to page SKU SLP-BMWF34-BC-GT6-6P-F-KIT. Confirm the exact BMW F34 vehicle record, original front-brake package, chosen rotor path, wheel status, aftermarket ET/J data where applicable, component quantities, hose interfaces, packaging and current commercial terms.
Keep the complete VIN in the private approval workflow rather than public page content. Do not transfer an F30 or F32 bracket decision to the F34 without review. Installation should begin only after the buyer and qualified installer have checked the approved bracket, rotor, wheel-clearance and hydraulic information.
