Getting your wheels sitting perfectly flush with the arches is one of the most satisfying upgrades you can make. It’s the detail that transforms a car’s stance from stock to stunning. Achieving that perfect flush fitment comes down to careful measurement, the right spacer thickness, and quality hub centric hardware.
What Does “Flush” Mean?
A flush fitment means your wheel and tyre line up evenly with the edge of the arch — not sunken in (tucked) and not sticking out (poked). The aim is balance: a clean, level look that gives your car a wider stance without rubbing or attracting MOT issues.
Step 1: Measure Your Wheel Position
Start by checking how far your wheels sit inside the arches. Use a straight edge (like a ruler or spirit level) held vertically against the outer edge of the arch, then measure the gap to the wheel face.
That measurement in millimetres is roughly the spacer thickness you’ll need to bring the wheel flush.
For example:
-
10mm gap = 10mm spacer
-
15mm gap = 15mm spacer
-
20mm gap = 20mm spacer
It’s that simple — but accuracy matters. Measure both front and rear as fitment can differ.
Step 2: Choose the Correct Spacer Type
Once you know your required thickness, choose a hub centric spacer in that size.
-
Up to 20mm: Use slip-on spacers with longer wheel bolts.
-
25mm or more: Use bolt-on spacers with their own integrated studs.
All Killer Offset, Demon, and Bimecc spacers from Stanced UK are fully hub centric and CNC machined from 6061-T6 aluminium, guaranteeing perfect fit and strength.
Step 3: Check for Clearance
Before final installation, always check clearance on full steering lock and through suspension travel. This ensures your tyres won’t contact arches, coilovers, or brake lines under load. For lowered or coilover-equipped cars, this step is essential.
Step 4: Match Your Bolt Seat Type
Factory wheels often use radius (ball) seat bolts, while aftermarket wheels typically use tapered (cone) seat bolts. Matching your bolt seat to your wheel type prevents vibration and uneven clamping. All Stanced UK spacer kits come with the correct seat style for your setup.
Step 5: Perfect the Stance
Once fitted, torque your bolts to the manufacturer’s spec and step back. A properly measured spacer setup gives your car the stance it deserves — balanced, confident, and perfectly flush.
The Bottom Line
Flush fitment isn’t guesswork — it’s precision. With accurate measurements and high-quality hub centric spacers from Killer Offset, Demon, or Bimecc, you’ll achieve a look that’s not only perfect to the eye but completely safe on the road.
