I didn't mean the subframe inserts, I meant the actual subframe connectors. It is good to do the tunnel brace together with the subframe connectors because you are there and have to modify the stock tunnel if you decide to use it. Plus it is only $90 extra and and it helps tie everything together for extra rigidity over the stock tunnel brace.
