I installed the US Cartool subframe connectors and torque boxes. After considering doing my own, I went that way because the US Cartool product is designed to follow the underfloor contours and makes for a very clean , unobtrusive install that looks closer to a factory framerail.Its a very well thought out product and gives great structural ridgidity to the car.
How much "give" room do those have fore and aft to make up for inconsistencies in how the floor pans are made? I'm assuming they can be pretty much trimmed to fit however, since none of these cars is really the same.
