Yes, I am currently running the 4.08 gears and LOVE them. After install, its a little pricey, but worth it if you're wanting to get the most out of your car NA. I wouldn't do it if you plan on boosting, I have ZERO traction in 1st and I burn all the way through 2nd when I'm on it (and thats with 305 rear tires) Hope that helps in your decision
