I went with Pfadt Sport Sway Bars as well - see this thread for my post -

I noticed an immediate performance gain in cornering with the Sport Sway Bars installed - my 2LT Camaro held curves tighter, the front end was level and there was no understeer I could feel.
I appreciate the time Aaron Pfadt spent with me to understand sway bars / springs / coil overs - his explanations plus the references from so many camaro5 members made going with Pfadt products the clear choice. Next up is are the coil overs in the Spring/Summer once the summer Pirellis are back on...
