In other words, should they be welded in at rear for my power level (521 hp/631 tq engine dyno). This will be on Mickey Thompson ET Street S/S, 235/60-15.

i have kind of the opposite of you, my PTFB connectors are welded at the rear frame rail & bolted to the front subframe, i did this in case i ever need to remove the front subframe. i will let others comment on the power level they are good to, but IMO subframe connectors arent really rated for power, they strengthen the car/frame no matter the power level... but at some point racers do weld them at the front & rear.
it comes down to how much of a race car you intend this to be, sounds like its mostly a street car & i dont think youd see any real benefit welding them at the rear too. plus it will be a hassle to ever remove the subframe for you or the next owner. with drag radials & limited track time its probably not worth it, they are doing their job as is but again all depends on how much you plan to race the car.
