They have some knowledge for mustang setups but reallly all they care about is selling products. They give false information on many products. They slap on a fake "market price" to make it seem your getting a good deal every time. They often rebrand products and sell them as another. They hide most negative reviews for products as well. Product review systems should ALWAYS allow all and every appropriate review good or negitive. I'd use other muscle aftermarket websites. I have up on American muscle a long time ago.
