    Great Product!
    Although it did take longer to receive my product than I thought it would have, it was well packaged and everything looked great. This is not the first time I've purchased a product off of you guys and I'm still very pleased. I plan on continue purchasing things from you in the future. The product itself looks great. It looks better than I can explain and it speaks for itself in person. Besides cosmetics, the performance side of things is outstanding. The car brakes a lot better now and the brakes are a lot more quite.
