    Product does NOT fit to spec as suggested
  

*by A***C on Reviewed in the United States on September 26, 2023*

Don't trust Amazon's suggestions for this product to fit your car.The product itself is just fine. I purchased based off of Amazon telling me this is the specific one for my car - and it's not even close to fitting. So be aware of that!

The were promised to fit my 2000 Mazda Miata and they did NOT fit, which probably a good thing because they are very cheaply made and I can't say that I would trust them!
