Installed the 6 piece set today in about 30 minutes with the help of the wife. In the Texas heat of 100 plus this afternoon this product works very well . Roof never got hot to the touch and a/c didn't have to be left on high . Didn't really notice a big improvement in sound proofing but I can't hear as well as i used to 20 years ago. Cost of product was $196 with my dealer discount . ( I own an auto shop ) It took about 5 days to arrive. Part # 82212463AB Did not remove hard top as instruction suggested.
