Hello! I just bought my first Z4. It's an E85 with the 3.0. So far I love this car, but I'm really hoping to get it out on a racetrack soon, and I think I'm just a little to tall to pass the broomstick test. I need about 1 more inch of clearance. Does anyone know of anything to extend the hoops behind the driver/passenger? Or I was thinking it might be possible to add a little more height to the windshield by attaching something to the hooks the top connects to. Does anything like this exist?
