I first purchased the outer SFCs from Heidts, then a week later the inner SFCs (Alstons) also from Heidts. Both are bolt-on, and I had the intention of bolting them in and then next year possibly welding them. I got the car about 23" of the ground with redundant support: jack stands and cribbing. (All because a buddy died via a car dropping on him a few years back, and the incessant nagging by my older son and wife.)

I'll cut the post short and say that I decided that, instead of bolting them in and drilling into the floor board for the outers, I would just take them to a shop to get them welded. I did do a lot of the prep work under the car.

The ride is so much better, as everyone said it would be. Why didn't I do this 28 years ago when I bought the car?

Very nice! Did you have them stitch welded on the outters or just the main points?

Just the ends are fully welded. I took it to www.big3racing.net and they said that they highly recommend NOT stitch welding along the rocker seem, which I had ask them to do. They reworked the exhaust around the cat to make enough room for the inner on that side.

It's a world of improvement. Not something that I could just bolt in, and not in the "four hours" as each set's instructions indicated.

I'm guessing the outers stop before they get to the torque boxes in the front for the bolt on applications?
Welding to the rocker pinch weld is a good thing. May be harder with round tubing instead of the rectangle stuff.

The subframes are a huge improvement on these cars.

I have the round Global West SFC, and used seam sealer in-between and along the pinch welds so that water could not get in and start rust.
