Has anyone used the Competition Engineering bolt-in subframe connectors P/N C3120? Can they be welded at a later date? Has anyone delt with a company called Pace Performance? They are an EBAY seller and they have the C E sfc for $50 cheaper than Summit. I am specifically looking for a bolt in sfc that can be welded later on. Thankyou in advance

If it can be bolted in, it can be welded in at a later date, just don't wait to long.

Note at CE site - installation may require some floor pan modifications

There are some CE SFC's that you have to cut a channel in the floor pan. Check on that B4 you buy.

I called CE and the floorpan mods they are referring to are the holes you need to drill to bolt the bars in. They make 2 different sets. The ones you refer to that require channeling the floor C3111, and the ones I am looking into C3120, which are designed to retain the factory style exhaust. I printed out the instructions which are very general. I was wondering if anyone had ANY PERSONAL EXPERIENCE with these with good pics. My search of the forum provided a couple of members with a few partial pics.
