why would you ever want to take them off?

Bolt in is not as strong as weld in. The only time you would want to get bolt in style sfcs are if you bolt them in, then drive to have someone weld them in.

If you are going to do it, do it right.

 

yea thats what i might consider is a couple of beads of weld down each subframe connector but i installed them and they look nice, it was easier than i thought, i just always take the hard route to doing things.
