Hollow Vs. solid sway bars
What is the advantage of a hollow sway bar over a solid one or is a solid one better? The hollow 34mm was the best GM had, but why is spohns solid? Or could GM not affort to put solid bars in?

weight is the biggest issue with the sway bars. Which is the reason GM made them hollow. A 34mm hollow is weaker then a solid 34mm. I believe that the material that spohn uses is alot lighter (chromoly) then the stock material. (possibly steel? iron?)

FYI, GM made the so-called 1LE sway bar, which was a hollow 36 mm. These came on some 89-92 Camaros and some 86-92 Firebirds in conjunction with a solid 24 mm rear. These are available at bone yards and, I believe, can still be had from GM. The front is part # is 14094344, the rear 10035033. I can provide the part numbers for the bushings (a higher durometer rubber) should you need them. I suggest, however, going with the greaseables from Top-Down Solutions or Spohn. Check my sig.

Hollow bars have the advantage of being much lighter, and only being slightly weaker. If you look at the stresses and Polar Moment of Inertia of a torsional member, like a swaybar, you will see all of the loadis carried by the outer portion of the member. So the middle or inner part really does nothing but add weight!
