I would definitely get the weld in ones. What are you looking to do?...strengthen the chassis, right?. Welds > Bolts for strength, plain and simple.

I've got BMR boxed weld-in SFC's and first you bolt them down...then you weld them. I would think most of the other SFC's are the same way.

weld them in, also, its important when you weld them that the suspenstion has no load on it. i.e. take it to speed shop let them do it right the first time

Correct, the suspension should be under full normal load when installing them. Bolt 'em that way and then weld.

Hmmmm......guess I had better get mine checked out! I physically tested and found no movement, but I suppose this isn't a full-proof method of inspection. I am trying to diagnose some unwanted thudding on hard launches. Narrowed it down to the TA, bushings, still could be the Tranny mount but not likely, eroded jouncers causing the T/A to be off-degree'd, or the subframes. Just had the rear diff changed, and no issues, plus the u-joints physically tested.

GD suspension issues like finding a needle in a haystack.

Now when you say weld....you mean w/ stainless steel rods correct?
