    TUBULAR REAR STUB

    Do you think there is any call for a tubular rear stub frame? What you would do is cut the frame off behind the fire wall then weld a tubular fame back on that would have your mounts for your coilovers already on it.The frame whould also have the strech 3.5" or 5" etc. already built in. the only thing you would reuse is the engine cradle. this is the way I am doing my F-355 .please give me your thoughts on this.

    Here is the simplest way to build a +3 / 355 kit. Make all of your modifications on the cradle and use coil over shocks and anti-bump steer from Held Motor Sports. You add 3 inches to the front frame rails and build new rear mounts 3inches forward of the old position, bolt in place, your done!

    Works like a champ; you do not cut the Fiero frame causing misalignments and structural challenges.

    If you're not confused, you're not paying attention.

    Re:TUBULAR REAR STUB

    MAPICS is absolutely right. It's best to stay away from the rear sub-frame attachment you mentioned. The reason I would stay VERY clear of the rear sub-frame assembly is because these assemblies are NOTORIOUS for being very unstable when the car is at higher speeds. Vibration is the number one complaint about them. This is just my two cents, I agree with the method MAPICS has used... very clean and neat and did not have to cut through the existing structure to achieve it. I don't imagine the process took very long to do either.
