Looking at SFC

Not sure which ones to get, I don't want to spend a whole lot but I don't want to cheap out. I think I am going to get the weld-in ones because the car is damn old. I'm looking here

What do you suggest and which ones do you have? (If you have them).

I got SLP DD bolt on and had them welded as well. Really noticed a difference afterward. I highly recommend them.

I've got Jegster SFC's from Jegs. They are bolt on's that can be easily welded after bolting them up and because of the way they route, you can also install Spohn SFC's for an even more rigid undercarrage.

Interesting...the price difference between the SLP weld-ins and the UMI weld-ins is almost 100 bucks. Would it be worth 100 for the name of SLP or should the UMI one's do the exact same thing?
