jeromio Posted October 2, 2001 Share Posted October 2, 2001 Huh? I think you'll need to make your question more specific. Some cars have major components isolated from the rest of the frame, such as the rear susp. on a late 90s T-Bird. The whole rear suspension and diff are attached to a sub-frame that is then attached to the rest of the car with rubber isolator bushings. There are other cars that employ a subframe for the engine/trans and/or front suspension. This is primarily done to make assembly line manufacturing easier, although sometimes it is done to isolate road noises and vibration. As to a sub-frame on a ZCar - ??? Maybe you're thinking about back halfing, where you either fab or buy a complete 4 link, solid axle rear with it's own frame that you then weld to the car (after cutting out much of what used ot be the rear susp. and frame)?

Guest Anonymous Posted October 2, 2001 Share Posted October 2, 2001 I believe he may be refering to a sub-frame connector? That would tie the front and back rails together, nothing bolt on like some of the other unibody cars unfortunately (that I know of anyway...)

Guest Anonymous Posted October 3, 2001 Share Posted October 3, 2001 Okay, sorry. There are many mentions of subframe connectors in this forum. there is reference to a commercial site - http://www.swracecars.com/ where subframe connectors can be purchased. But what exactly are they, especially in the context of the z which has no real "sub-frames" to connect, being a unibody and all? Where do they connect on the Z(i.e. do they attatch to the lower control arm origins front and rear or the TC rod origin or what??)? Has everyone done this the same? What if I don't have to replace my floor, can I just add a box section channelfront to back? Interior or exterior? Thanks.
