Question 1

What is a Honda chassis code?

Accepted Answer

A Honda chassis code is Honda's internal identifier for a specific generation of vehicle. For example, the FL5 refers to the 11th-generation Civic Type R (2022 onward), and the FK8 refers to the 10th-generation Civic Type R (2017-2021). Honda enthusiasts use chassis codes because they identify the exact platform underneath the car, which determines wheel fitment specifications including offset, width, hub bore, and brake clearance.

Question 2

How do I find my Honda chassis code?

Accepted Answer

Your Honda chassis code can be found in several places: on the VIN plate inside the driver's door jamb, in your owner's manual, or by decoding your VIN through Honda's online resources. You can also use the chassis lookup tool on this page to identify your platform by model year and trim.

Question 3

What is the difference between an FK8 and an FL5 Civic Type R?

Accepted Answer

The FK8 is the 10th-generation Honda Civic Type R, produced from 2017 to 2021. It uses the K20C1 turbocharged 2.0L inline-four engine. The FL5 is the 11th-generation Civic Type R, produced from 2022 onward, using an updated version of the K20C1 with revised aerodynamics, suspension geometry, and chassis tuning. The two platforms have different wheel fitment specifications, which is why each has its own dedicated fitment guide.
