The quality of this cover is excellent. The instructions are easy to follow and everything fits just right. Special addendums for spacers and shims work perfectly. I installed this alone and it took about two hours but I could do it in half the time having done it once. The only suggestion I have is to add some teeth to the outside washers at the front to bite into the vinyl when tightening the inside knobs. It was quite awkward to hold the disc with pliers and turn the knobs at the same time.
Great product for cheaper price
I work as a GM tech and am very picky, but didn't want to spend big bucks on something I will only use half the year (only on in winter) so I settled on this one from the reviews it had. Came quick in a good box, only took about 5-10 minutes to install and adjust. Drove 1800 miles the very next day and it was great for traveling with storage in the back, there was no wind noise, and even with it pouring rain out there was minimal water inside. Would highly recommend
