First off, I have to say that Stancefactory has great communication and has patiently answered my questions/requests in a timely manner. Last year, they flashed Euro/CSL SMG software for me with ease. They were quite knowledgeable and helpful in whatever I needed done.
This year, I ordered the BC coils with their winter promotion and from start to finish it's been great; complete with custom spring rates/valving for the look I was going for. The installation was quick/painless and the pricing is fair/reasonable.
No surprises with these guys. Highly recommended!
