I just received all of the parts for my order from the guys at CSG to built my SCCA T4 FR-S.
I don't know that they need more positive feedback, but I particularly liked how David talked me out of buying certain parts ( and then talked me into another) but these guys do not just want to generate revenue, they truly have your best interests in mind.
Very good advance including contacting Manufacturer for assistance and clarifications
thanks @
