It appears that the AFE is non-adjustable and 32mm. It is tubular also but with unknown wall thickness. One could assume it is similar to the OEM wall thickness; however, doesn't the OEM bar have a reduction in cross-section in the middle? That fubars the analysis a lot. You could at least calculate the increase in stiffness vs OEM by assuming the OEM bar is not necked down and ratio the diameters to the 4th power -- then you would know the actual increase is somewhat larger than that value since the AFE bar is a continuous cross-section. All of this of course assumes the moment arm is the same length, but that is easy to measure between the two. AFE sould be able to answer these questions.
The H&R bar is 30mm and solid? Not sure. At least it has two adjustment holes. It is priced at $417 though...
The other potential cheap option is to use the M3/4 comp package sway bar. I assume it's larger but just don't know the sizes to compare. The parts catalog no longer calls out sway bar diameters. It can
be had for $202 though, new.
All that said, it does appear the Dinan bar would be what's needed to tune the car, especially if trying 275/35-18 square versus 275/35-18F & 305/30-19 rear, etc.
Sounds like a fun time to be had nonetheless!
