I purchased one of the UPR K-members several months ago to test on our shop car. Well after installing it and driving on it for awhile I decided to let Jeremy know my feedback on his product. The fit and finish is excellent on these, and the amount of room it opens is unbelieveable. The only concern I had with the K-member was the fact that the engine sits a tad bit lower causing some turbo piping clearance problems. In a matter of minutes after sending my email Jeremy contacted me and shipped out the necessary spacers to rectify my problem. Thanks again guys for great products and great customer support.
