Author Topic: Sub-frame connectors (Read 3795 times)

Are those frame connectors really nessesary? Are they a waste of money

or not? I'm not building a street rod and not planning on mashing out (ok

maybe once or twice), but only to educate rice rockets. Are the ones from

NPD good? Also, I do plan on lowering the stance(two or three inches).

Will the connectors get in the way?

The frame connectors all depend on how much horsepower and torque you are putting into the car and engine. Once you hit about the 450-500hp mark, then I would think about frame connectors.

to add to hitman, my motor builder is also tying my frame and he said the tubular ones from npd and classic industries are junk and he would never use them again, so he makes his own out of box steel and he's never had a problem with them.

I think if you want to improve the handling of your car these will also help take some of the flex out of the body.

Competion enginering makes a good pair of boxed steel bolt on connectors. I used these but also welded them.

theres an advertisement of some subframe connectors in of the magazines, and for an additional cost it will get you an x brace that connects opposite sides in between the rails, almost like a convertable frame.....really looks good....

Welded in SFCs are one of the most immediately noticeable changes you can make to an F-body from a handling perspective. If you're worried about bodyflex because of the torque of a monster motor, then as Brett said, you probably don't have much to worry about till you start making serious power... but purely from a handling perspective, SFCs tie the unibody and subframe together forming a much more rigid/less flexible unit. Highly recommended if you're trying to make a handler out of your car.
