The 2023 Toyota GR Corolla wheel spacers’ structure is based on Japanese cars’ traditional wheel studs, with additional wheel studs and lug nuts to increase the wheel clearance. When installing 2023 Toyota GR Corolla wheel spacers, there is often a problem that the stock wheel studs are not compatible with the wheel pocket. Do you need longer wheel studs to solve this problem, or what wheel spacers do you need to buy to fit the 2023 Toyota GR Corolla perfectly? We will solve the above problems for you.
The wheel studs of the 2023 Toyota GR Corolla wheel spacers are generally made of steel alloy, the structure of the 2023 Toyota GR Corolla requires the wheel studs to bear more shear force, so the quality of the wheel studs will be an important reference when selecting 2023 Toyota GR Corolla wheel spacers. General wheel studs can use wheel bolts grade as a reference standard. 8.8, 10.9, and 12.9 is the common wheel studs’ grade. To better withstand the vehicle ground shear force, we recommend 12.9-grade wheel studs.
Do 2023 Toyota GR Corolla Wheel Spacers Need Longer Studs?
The 2023 Toyota GR Corolla wheel spacers can be divided into the common bolt-on and slip-on types. Most customers choose bolt-on wheel spacers because they are easier to install and reduce the process of removing the stock wheel studs. We will explain whether longer studs are needed to construct bolt-on wheel spacers. Put the bolt-on 2023 Toyota GR Corolla wheel spacers bolt holes through the wheel studs of the hub assembly, then use aftermarket lug nuts to secure. The wheels will be mounted on the 2023 Toyota GR Corolla wheel spacers, using stock lug nuts to secure them.
In the above bolt-on type 2023 Toyota GR Corolla wheel spacers, you do not need to replace the longer wheel studs. Because the stock wheel studs will go through the wheel spacers, the protruding part will be hidden by the wheel pocket. Normally, bolt-on 2023 Toyota GR Corolla wheel spacers under 15mm are prone to incompatibility problems where the wheel studs’ length exceeds the wheel pocket’s depth. Cut out the extra wheel studs to match the 2023 Toyota GR Corolla wheel spacers, or choose the thicker one.
Another type of slip-on 2023 Toyota GR Corolla wheel spacer requires extended wheel studs for installation. The structural forces are safer because the 2023 Toyota GR Corolla wheel spacers do not need to withstand shear and other external forces. Still, the requirements for aftermarket wheel studs are higher. BONOSS recommends the use of 12.9 grade for aftermarket wheel studs, and their performance will allow the use of wheel spacers.
The length of the wheel studs for slip-on 2023 Toyota GR Corolla wheel spacers depends on the stock wheel studs and the thickness of the wheel spacers. Assuming the length of the stock 2023 Toyota GR Corolla wheel studs is 30mm and the thickness of the 2023 Toyota GR Corolla wheel spacers you purchased is 15mm, then you will need 30+15=45mm extended wheel studs. The longer 2023 Toyota GR Corolla wheel studs will ensure that the lug nuts threads have enough safe turns to generate clamping force to lock the wheels. For example, for M12x1.5 threads, it needs at least 8 turns of safety, and the thread locking length needs to be 10mm.
How to Choose the Safe 2023 Toyota GR Corolla Wheel Spacers?
The safety of the 2023 Toyota GR Corolla wheel spacers is closely related to the quality of each part. We will first discuss the quality of the materials used in the 2023 Toyota GR Corolla wheel spacers. Most 2023 Toyota GR Corolla wheel spacers are made of forged aluminum alloy, a safe material. For example, BORA, H&R, and Eibach have chosen 6061-T6 forged aluminum alloy for their 2023 Toyota GR Corolla wheel spacers, which provides a tensile strength of 42,000-45,000 psi and yield strength of 35,000-40,000 psi, both of which will ensure that the 2023 Toyota GR Corolla wheel spacers will be safe. Toyota GR Corolla wheel spacers will not fracture, distort, or deform plastically.
A few brands that focus on 2023 Toyota GR Corolla wheel spacers will offer the option of 7075-T6 forged aluminum alloy, which will provide approximately 40% higher performance than 6061-T6, with a tensile strength of 74,000-78,000 psi and yield strength of 63,000-69,000 psi. The performance figures will allow the 2023 Toyota GR Corolla wheel spacers to withstand the impact of external forces during aggressive driving and, to a certain extent, make customers feel safer while driving.
The wheel studs of the 2023 Toyota GR Corolla wheel spacers will be one of the important factors for safety. Both bolt-on wheel studs and slip-on type longer wheel studs need to withstand the shear force caused by vehicle acceleration, and the lug nuts need to withstand the clamping force and static friction under standard torque. BONOSS offers JIS SCM440 steel alloy wheel studs for wheel spacers, and you can match them with slip-on type 2023 Toyota GR Corolla wheel spacers.
What Are the Benefits of Using 12.9 Grade Wheel Studs?
Wheel studs are structurally similar to wheel bolts, requiring these fasteners to have excellent proof load and ultimate tensile strength to withstand the shear forces generated by vehicle movement. However, there is a big difference in the performance of 8.8, 10.9, and 12.9-grade products, and the grade of wheel studs is usually clearly engraved on the surface. 8.8, 10.9, and 12.9 refer to the 2023 Toyota GR Corolla wheel spacers wheel studs’ performance grade mark, which consists of two parts of numbers, which are wheel studs’ material nominal tensile strength value and bending strength ratio, generally indicated by “XY,” such as 8.8, 10.9, 12.9, etc.
Performance grade 10.9 2023 Toyota GR Corolla wheel studs have a tensile strength of 1000MPa and a yield strength ratio of 0.9, yield strength of 1000 x 0.9 = 900MPa, while grade 8.8 2023 Toyota GR Corolla wheel spacers wheel studs have a tensile strength of 640MPa and grade 12.9 wheel studs have a tensile strength of 1110MPa. The difference between 8.8 and 12.9 is 470MPa, which will directly affect the vehicle’s driving safety.
