I'm planning on buying the Spohn SFC's. How should they welded? How hard is the job and how much should I expect to pay for a shop to do the whole job?

 

I had the ones on my fourth gen put on for $80. I had a local muffler shop put them on. Little did I know they were the most expencive place in town. O well.

Good luck

 

those SFC's could take anywhere 2 to 3 hours to put in, properly, so what ever their shop rate is.

Here's the LINK to Steve's page, showing how they should be installed.

Welded at the LCA area, every 6 - 8 inches all along the rocker, then at the trans mount area.

You may want to loosen the carpeting along some of that area just in case. Then I'd email Steve tech@spohn.net with any other questions/concerns
