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.

Last week I spoke to Brian, I ordered a aluminum Koyo 37mm radiator for 97 Miata. Brian, you run a first class show! It arrived the next day. It is a fully polished work of art. The welding is perfect. The fit is perfect, old radiator slipped right out, new one slipped right in. Perfect. I am very pleased. Thank you.

Hi Brian, I just bought a heatshield and a cruise control relocation bracket for my '95 Miata from you. It is in the mail now. Thanks for such fast service. (My cruise is just wrapped up in a microfiber shoprag at this time!)
