BONOSS Forged Active Cooling Hubcentric Wheel Spacers
6061-T6 Forged | TÜV Quality | 10-Year Description 1.What this does
Your wheels currently sit tucked inside the wheel arches. These spacers move each wheel outwards by 30mm (about 1.2 inches), so the wheel sits flush with the arch instead of hiding inside it. The axle ends up 60mm wider, which means less body lean when you go round a corner.
Please note: this listing is for TWO spacers (1 set)— that\'s one axle (front or rear). For all four wheels, please order 2 sets.
2.Will it fit my car?
Please ensure that your vehicle\'s axle hub and wheel hub meet the following specifications.Bolt Pattern (PCD):5X120 Center Bore / Hub Bore:72.5mm Thread size:M14x1.5 Wheel Fasteners: Lug bolts
If you are unsure, please contact customer service and provide your vehicle make, model, and year.

3.Range Rover Sport Wheel Spacer Installation Steps:
1.Pre-loosen all bolts before lifting the vehicle.
2.Lift and support the vehicle. Remove the wheels.
3.Clean the hub mounting surface—use a wire brush and brake cleaner. This step matters more than most realize; rust and debris trapped under a spacer are exactly what cause vibration.
4.Seat the hub-centric spacers onto the hub register. The bore size matches the Range Rover Sport hub perfectly.
5.Hand-tighten the supplied lug nuts in a star pattern.
6.Torque to the recommended specification, also in a star pattern.Torque to 140 N·m (103.5 ft·lb). Ensure at least 7.5 full turns of engagement and a minimum load-bearing thread length of 12mm.
7.Mount the wheels. Torque wheel lug nuts to factory specification.Wheel Tightening Torque:150 Nm
8.Lower the vehicle. Done.
4.Range Rover Sport:Real-Vehicle Measurement Data
Worried that your factory studs will protrude and prevent the wheel from sitting flat?
We\'ve measured it — on a stock setup, a 30 mm spacer clears without issue. Factory studs protrude approximately 28 mm, and OEM wheels have deep pockets on the back.
Since its establishment, BONOSS has consistently based its wheel spacer production on real-vehicle measurement data to minimize driving vibrations caused by precision issues. With over 1,000 real-vehicle measurement cases and growing, BONOSS ensures every product delivers guaranteed driving safety.
5.How do I know if I need to trim my factory studs?
To avoid trimming before you buy:
Note: Some wheels have misaligned recesses – double-check that the studs will actually line up with the pockets.
If the wheel spacer is too thin and the factory studs protrude past the spacer face, the wheel won\'t sit flush. You have 3 options:
- Go with a thicker spacer.
- Trim the excess stud length.
- Replace the original studs with extended studs. Use Slip-on wheel spacers.
6.Frequently Asked Questions
Q1. How to measure the correct spacer thickness.
Place a straight edge against the outermost part of the wheel rim/tire, then measure the gap from the wheel face to the fender lip. For a safe daily-driver setup, we recommend choosing a spacer that is2–3mm thinnerthan that measurement.
Q2. BONOSS torque specifications.

1/2-20UNF
140 N·m (103.5 ft·lb)
8.0 turns— Load bearing shaft length ≥ 11mm
Q3.Why Use a Torque Wrench Instead of an Impact Gun?
Impact guns deliver high-frequency impacts. Without properly calibrated torque-limiting extensions—often misused in shops—clamping force varies, causing inconsistent torque across lug nuts. This uneven load can warp rotors, damage threads, and, with spacers, exert uneven pressure on the hub-centric seat. A torque wrench ensures consistent, measurable clamping force, reducing these risks.
Q4. What if I switch to different wheels later?
When changing new wheels, you need to check the following:
- PCD (bolt pattern)
- Center bore (hub bore)
- Lug seat type
If the new wheels have thesame PCD and center boreas your vehicle, you can reuse your spacers (assuming thickness still works).
If they differ, you\'ll need awheel adapter. BONOSS offers custom adapters – just contact us with your vehicle\'smake, model, yearand the new wheel specs.
Q5. My tires rub the fender liner after installing spacers – how do I fix it?
If the liner isplastic, you can gently reshape it:
- Use aheat gunto warm the rubbing area until soft.
- Push the plasticinward/backwardwith a tool to gain clearance.
- Hold it in place until it cools – it will retain the new shape.
Note: This works for plastic liners only. Do not attempt on metal components.
Q6. What if vibration occurs?
BONOSS spacers are precision-machined to within 0.02mm tolerance, so vibration is highly unlikely under normal conditions.
If vibration does occur, please check the following:
- Hub and wheel mounting surfaces– Make sure the hub face and wheel mounting surface are completely clean and free of rust. Any debris or corrosion can prevent the spacer from seating flush.
- Torque and tightening sequence– Always use a torque wrench and tighten lug nuts/bolts in a star/crisscross pattern to the specified torque.Neveruse an impact gun (air or electric) for installation.
- Spacer type– If you are using a spacer without a hubcentric ring , the chance of vibration is significantly higher. We strongly recommend hubcentric spacers for a vibration-free fit.
- Wheel alignment– If you\'ve ruled out all the above and vibration still persists, have your wheel alignment checked by a professional shop.
Q7.Started out smooth, but now feeling vibration after some miles?
Temperature changes can affect torque over time. After the first 100 miles or so, simply re-torque your lug nuts to factory specs. That usually takes care of it. A quick check is all it takes to keep things right.
