When I did the longitudinal Chrysler swap on my 88 I had to remove the factory sway bar to make room for the transmission. It's been a couple years now and I think I'd like to put one back on again to get rid of some handling issues I believe are cause by the removal of said bar. Here are a few pics of the underside showing what I have to work around.









I've seen pics of the fiero store sway bar on the 87's, but I'm not sure about mounting one to the bottom of the cradle. I'd be worried about catching it on something. The other option would be to mount it in the area where the cradle raises up by the rear mount but as you can see the transmission pan is in the way so I'd need a bar with an offset. Either way I'd have to make a custom bracket on the suspension for the bar's arms to connect to.

Something like this:



I'm open to suggestions here as to shape, size, brand, and mounting options. IIRC, the stock 88 rear bar is 1" so I assume I should replace it with the same size. Is there a rule of thumb as to the relationship between bar diameter and arm length?

I have found that installing (anti) sway bars requires careful matching. On one Fiero I added the Fiero Store rear bar to an 87. That seemed to improve handling. On my current Fiero I tried adding the heavier Addco bar to the rear and got tons of over steer. Had to change to the Addco front bar as well. to correct things Point is that on the 88 Fiero GM did a pretty good job matching front and rear suspensions. If it were my car, I would keep the stock 88 sway bars

The problem is that I can't use the factory sway bar because the transmission now occupies the space that the factory sway bar used to run through. That is why I need to find one to go under or behind the tranny pan.
