I put my year, make, and model into the website, and I purchased what came up, why doesn't it fit? While our website is a good tool for an estimate for what fits your vehicle each owner modifies their vehicle differently. Meaning you could have different modifications done to your vehicle that causes the wheels/tires not to fit while they could work on another person's vehicle who performed the necessary modifications to make the setup work. This is why we suggest using the gallery for a reference. You have to pay a restocking fee because we now need to pay individuals to return, clean up, and restock the item to our shelves to be resold. These are large items and take a lot of work to be put back into our inventory. Yes, while we can't guarantee that a product will never fail, as long as spacers are installed and measured for correctly they are generally safe. If your purchase does not fit, you can certainly return the product however, a return and restocking fee of 20% will apply. The product can also not be used/driven on in any way. We highly recommend a test fit once you get your new wheels, please bolt them up (carefully) and spin them on the vehicle before driving on them to ensure they fit correctly. Our customers are determined to push their vehicles to the limit while showing off their own unique style. Each customized vehicle has its own personality and we want to help our customers achieve any look they’re after to complete their dream vehicle. However, there are certain risks that come with stretched tires. Stretched tires give a distinct, minimal sidewall look that can help showcase your wheels and dial in perfect fitment. In minor stretch applications, there are minimal to no inherent risks. But, in extreme tire stretch applications, this can result in debeading or tearing of the tires sidewall. The more the tire is stretched, the more likely you may run into one of these issues. Stretching a tire onto a wider wheel may void the manufacturer's warranty depending on the brand and size of the tire. If your application is considered stretched, there will be a note listed during the checkout process before going to the cart for purchase.

The forces imposed on the anti-roll bar subject it to constant twisting and flexing, which in turn put its various rubber mounting bushes under great load. The bushes gradually wear and lose their effectiveness. Over a period of years the rubber hardens and tends to crack.
Instead of sharing a common axle, each wheel on a car with independent suspension is independently attached to the body or subframe. Different spring combinations may be used.
