Frequently Asked Questions
Function and Form’s 4×100 wheel spacers are engineered for precision fitment, clean stance correction, and improved wheel clearance on vehicles using a 4×100 bolt pattern. These hubcentric spacers are ideal for dialing in offset, gaining clearance for suspension or brake upgrades, and eliminating tucked wheel setups—all while maintaining proper load distribution and OEM-level safety.
Unlike flat spacers that can introduce vibration or stress suspension components, these are true hubcentric wheel spacers, built to center perfectly on the hub. That results in balanced wheel rotation, reduced wear, and improved high-speed stability. The center bore is machined to 56.10 mm, providing direct fitment on popular 4×100 platforms like Honda Civic (EF/EG/EK), Mazda Miata (NA/NB), Toyota Corolla, and more.
Each set of 4×100 wheel spacers is CNC-machined from hot-forged aircraft-grade aluminum. This material offers a superior strength-to-weight ratio that exceeds steel, keeping unsprung weight low while maintaining durability under demanding use. The result is a spacer that can handle spirited driving, track conditions, or daily commuting with confidence.
Available in 5mm and 12mm sizes, these spacers are perfect for achieving flush fitment without throwing off suspension geometry. They’re especially useful when clearing coilovers, fitting wider tires, or compensating for aftermarket wheels with conservative offsets.
Installation is straightforward and frustration-free. Each spacer includes straight knurled edges for better grip during install and removal, even with gloves or limited access. Integrated micro-channel grooves prevent the spacers from seizing onto the hub or wheel due to heat or corrosion, making tire rotations or future adjustments easy.
The stealth Undercover Black finish helps the spacer visually disappear behind the wheel while protecting it from corrosion. Every set is sold in pairs, allowing for easy adjustment on either the front or rear axle. Pair with Function and Form coilovers for a fully dialed-in suspension and fitment setup.
Whether you’re building a track-ready Civic, restoring a Corolla hatch, or tuning your Miata for better stance, these 4×100 wheel spacers deliver the precision, durability, and clean execution Function and Form is known for.
