I'd say they would probably be best. They only sell weld in though because they say "Bolt-on connectors do not work because the bolts cannot be properly tightened due to the lack of structure in the car’s subframes." They're pretty cheap too, ranging from $79 to $149 for full length. See for yourself...
Maximum Motorsports is a great brand to get, I had mine welded in last year, and its unfortunate that I had a little accident in the garage and crushed my fuel lines and it is going to be extremely hard to change them with my SFCs welded in place!
If they are going to do the welding than buy some "square stock" and make them. Trust me. My welds are not the prettiest. But they get the job done. Just saving ya some extra $$$. or you can buy some. Steeda, Maximum motorsports, kenny brown are all good companies.
