Very high quality materials and workmanship as far as i can see.(rebuilt j79 &j52 jet engines in my time in usmc as a jet mech) And the quality is the same.

Just had the Pfadt coilovers installed 6-4-10 along with my Pfadt arsenal that i already have such as ,racing motor mounts, trust me guys once these motor mounts break in you will be soooo happy, front and rear sway bars( racing type) strut stiffers and more on the way. This coilover setup is awesome. I had dynotuned performance install and i am happy. Running 573 at the rw and all Pfadt stuff hangs in there
