The all-new 2025 Honda Civic Type-R FL5 is a performance beast, combining blistering speed with agile handling. To get the most out of this hot hatch on the road or track, upgrading the wheel and tire setup is a common modification. Wheel spacers allow you to push the wheels out for a more aggressive stance and improved handling. But what size wheel spacers should you get for your Type-R FL5? Let’s take a look.

What size are 2025 Honda Civic Type-R FL5 wheel spacers?

The optimal wheel spacer size for the 2025 Civic Type-R FL5 is generally between 15-25mm at each hub. This gives enough clearance to avoid rubbing issues while providing improved steering response and high-speed stability from the increased track width.

Specifically, most owners go with:

  • Front: 15-20mm wheel spacers
  • Rear: 20-25mm wheel spacers

The wider spacers are used at the rear to help counteract understeer tendencies and put more rubber on the road under acceleration. That said, some prefer a square stance with the same spacer size used front and rear.

It’s important not to overdo it with wheel spacers. Stick to reputable spacer brands and have them properly installed by professionals.
