before everyone jumps on me for not searching, ive searched pretty extensivly on here and world.net. i havnt found concrete answer.the question i have with this swap is on the f4i subframe, does it bolt directly to the f3 frame without problem?

 

The F3 frame is welded. There is nothing to bolt onto. It's also a steel frame, not aluminum.

 

so your saying the f3 subframe is welded onto the main frame? how do people do this swap then?

then the only question left is the one not answered.. how do you join aluminum to steel??? cause i'm not into trusting nuts and bolts to hold my fat @zz off the rear tire lololol
