If you dont mind me asking what were some of the concerns?
Timing is a big concern for me as I want to get this car done as soon as possible due to my upcoming work schedule. I was quoted 3 weeks plus a week or so for coating. I have seen 2 Doc Race kits in person and the quality and fitment were spot on. Both owners were happy with install procedure, fitment, and performance. I have seen one VM top mount (now ACF) that looked and performed great as well per the owner. My only concern with ACF were some reporting lack of meeting anticipated delivery dates and poor communication. Not something I have time for right now. Either way I think both are great kits.
Whatever you do don't fall for the cheap money up front companies. There are no victims, only volunteers.....
