87 CRX SI compared to 86 CRX HF Suspension?

[Ted the Honda Guy]

Hey guys I am trying to build an 86 CRX HF as a circle track car. I am just going to drop the motor in from my 87 Si and deal with the headache of installing another wiring Harness. My question is "Is there any difference in stock suspension comparing the two cars?" I know the DX and Si have the same suspension. But I am not sure if spring rates, torsion bar thickness, or sway bars are any different?

Thanks Guys
Ted
