How much difference between ET35 and ET45?
2 Answers
ET35 and ET45 differ by approximately 10mm. Here is relevant information about ET: 1. Concept: ET refers to the wheel offset, which is the distance between the wheel mounting surface and the centerline of the rim. The smaller the offset value, the more the wheel protrudes. 2. Considerations: If the wheel ET value is too small, the wheel will protrude from the vehicle body and may scrape against the fender. Therefore, this value requires careful consideration and precise calculation. The offset value determines the actual position of the wheel on the axle, including its lateral position and the track width between two wheels on the same axle.
I've been modifying car wheels for years, and the 10mm difference between ET35 and ET45 is quite common. The wheel offset value represents the distance from the wheel's centerline to the mounting surface—the smaller the number, the more the wheel protrudes outward. For example, ET35 is 10mm lower than ET45, which creates a significantly different visual effect. Swapping to ET35 gives a fuller wheel arch and a cooler stance, but the risk is potential rubbing against the inner wheel arch or brake components. I once nearly scraped the fender during a modification. A 10mm difference is often discussed in the modding community because it affects vehicle stability and tire lifespan. For instance, replacing the stock ET45 with ET35 increases steering load. Before changing wheels, it's advisable to measure wheel well clearance and suspension design—safety outweighs aesthetics. In short, 10mm may seem small, but it can make or break your setup, so don't overlook it.
