I am in so deep with Mazda there was no call for me. A lot of the Grand Am stuff crosses over so I have a little advantage not starting from scratch. Cage design is critical because of the lack of a B pillar. I am staying with a 17" wheel because there is not a real gain in width we can get with the 18" and weight is not worth it. Gearing is better with 17 as well. I will share anything you want to see on the build. Shooting for 280hp but will settle for 215. You planning to run STU National?
