I made my sfc's out of flat stock (1 3/4"x1/2" IIRC) and made the ears for the seat braket bolts. The steel cost 40 (enough to do two sets), then welded them in. I took my time with the welds and had no problem with the carpet getting hot. It took about an hour to fab the connecters, and about another 90 mins to install them. The reason I went with flatstock was for the clearance.
Food for thought I guess.

 

How do you like the result? And how long was the steel?

 

Yeah i do wish i knew how to weld but i would rather not learn on my car especialy when im near the fuel tank. I dont know yet but i should have the car tomarrow or friday and i wont know how they feel for a month or 2. I would just buy the powdercoated one because spray paint will faid after time and they will chip, just my.02.

 

whats better, welded on connectors or bolted on? and also how do you know the strenth of steel, is 14 gauge stronger than 20 gauge? (lower number=more strength?)

 

Yes the lower number will usually mean a stronger piece (the lower number, the thicker; the same goes for wire, 4 gauge wire is really thick, where most of your electrical stuff in your car is 12-16 gauge)
From everything I've ever read; the full length subframes are supposed to be better than the bolt ons. I can't tell you from experience, because I don't have any.

 

Love them. Great clearance like I said, and really improved the feel of the car.
I dont know the exact measurement, and my car isnt at my house now so I cant measure, but Im almost sure it was about 8ft.

 

Weld the sub connectors. I'd get the unpainted ones as you really are not going to be able to get a good weld thru paint.
Paint should be a good spray can primer and then what ever you want for color. I'd use 'Krylon' brand
Finally, the LOWER the number the HEAVIER the gauge of steel. This does not have ANYTHING to do with strenght of the steel as thats the alloy of the steel. When I make frame ties I use a 'mild' steel. SAE 1020,1030 is what this is.
I would think that some one who knows what they are doing should be able to put these on in a couple hours......
