My mid-12 second car must be an underachiever because after 80 or so runs on slicks with no subframe connectors and 1.68-1.70 60 foot times, I haven't seen any signs of tweaking or damage yet.

But I do want to add them to see if they will improve my 60 foot times or ETs. Anyone have any before and after data regarding that?

Do the F.A.S.T. cars run subframe connectors?
