What is the best or preferred order of events to do these mods in? 1.spring relocation 2.torque boxes 3.sub-frame connectors, the laser cut to fit the floor ones and 4. mini-tubbing I've read a lot of info on each mod individually, and have all the parts ready, it's just where to start once I get the undercoating off.

btt, is there a logical sequence or is it just do them and it doesn't matter?

I'm no chassis expert, but I believe you want to do spring relocation before minitub, as the first helps dictate the position of the second, and then do your subframe connectors and then your torque boxes last.

I have installed subframe connectors on two cars, both times on cars with exisisting torque boxes. One car by slotting the torque boxes installing the connectors and then welding up the slots, and the other car by peeling back part of the boxes installing the connectors and rewelding the boxes back in place.

In other words, Move your springs, install your minitubs, install your connectors and then put the torque boxes on last. I have never altered the spring location or installed minitubs though. I'm sure many guys have here though.

The slotted ones before final grinding, sealing with high-quality, paintable, black 50 year roof and gutter caulking and finish coating with Resto-Ricks undercoating...Notice how close the front spring mount and wheel house are to the parts. It's something to consider when determining your project sequence.

Thanks
