I installed a Whiteline QuickRelease Tower Bar today. The install went very easily. Took about 30 minutes start to finish. I had to do some minor cutting, but it looks pretty clean. It can go back to stock without any real notice. I haven't really driven the car much yet, but based on looks alone, its totally worth it. You can notice it through the window, but if you dont want to have anyone see it, just pull the shade. After I get the windows tinted, it'll be even better. First time posting pics here, hope they work!
