Unless there'* something funky about the 2k'* I don't know about, you have a solid bar.
All 4 of my FE2 bars are solid.
Some early FE1 bars in 92 ONLY (some 91'* maybe) were hollow.

Well maybe we have discovered an anomoly.
My front is definitely positively hollow and 30 mm
My rear is solid and 19 mm.
My code written on the spare tire cover says FE2. :?

A solid bar will not be much stronger then a hollow bar of the same size. The strength comes from the material farthest from the center. A hollow bar is smarted because it has less weight then a solid bar of the same strength.

Mark Fahey has aftermarket swaybars on his SSEi, he got them from this company: http://www.sanerperffab.com

A solid bar has a higher torsional strength than a hollow one.
Compare the strength of twisting a hollow drinking straw and then compare to twisting a solid similarly sized solid plastic rod.
Big difference.
The strength of a sway bar increases by 4th power of it'* diameter.

The hollow bars are not equivlelent to a drink straw, they are much thicker walled.
The material in the center does nothing compared to the material on the outside. It'* basic engineering, that'* why they make things like I beams and C-channel. All of the strength is in the outside. Obvously a solid bar will be stronger, but not nearly as much as increasing the diameter a small bit.
The strength is determined by moment of intertia. Intertia is the pi times the diamter to the forth power divided by 64.
So a 2" solid bar would have a moment of .785, a 2" hollow bar with a .5" diamter hole through the center would have a moment of .785 - .003 = .782, barely a difference. Even a 1" hole would give you a .736 Moment.

That might be true for a thick walled bar but the hollow bars we have are very thin walled, as you can see in pics people have taken of broken and cracked ones.
The moment of Inertia of a thin walled bar = M(mass) x R(radius)squared
The moment of Inertia of a solid bar = 1/2 M x R squared
Stress = Torque x R / Inertia
So a solid bar of the same diameter is twice as strong in torsion as a thin walled bar.
I know these things because I am an Engineer.
