Thank you. You have rated this product.

This new style tensioner assembly for the JR M45 supercharged Miatas is now standard in all systems and makes a great upgrade for the older system. Redesigned Heavy-Duty Black Anodized Billet Tensioner Bracket with crowned idler pulleys. The crowned design results in the drive belt tracking in the center of the pulley all the time, instead of riding on one edge or the other. Complete tensioner system eliminates belt slipping issues, especially useful on higher boost systems. Includes 2 new idler pulley as well. Power Steering is required for new belt tensioner. Belt sold separately.

I red'all the parts in the order I placed and installed them in my car yesterday. I am beyond happy. The install went without a hitch. The results were fantastic. The new brakes track straight, make no noise, and stop the car authoritatively. The new rotors look pretty cool, which we all know isn't all that important, but having 6 women offer to bear your children, because your car looks SO cool is a good problem to have. Thank for great products and service.

I think that Brian Goodwin is the perfect example of what is good about the aftermarket industry. He is one of the few vendors that actually cares about his customers. He is the example that all companies should be trying to emulate when it comes to customer service. Not to mention his ingenuity and desire to improve on what is already a great car. I have never had a "bad" experience with Good-win-racing. Well, except for the constant temptation to SPEND MORE MONEY.
