One thing to keep in mind is that the name "Lingenfelter" may increase the value of the car if you decide to sell it down the line. If I were to be looking for a car, and I found one that had some mods on it, I'd be far more interested in one that has been worked on by a proven performance shop (parts) than a fairly no-name shop and/or parts.
I'm not saying the quality isn't there with other brands, I know it is in many cases, but the name will help you sell the car down the line if you are so inclined.
Just a thought, something to keep in mind. Good luck!
